CALIX 244X SERIES GPON ONT HARDWARE INSTALLATION MANUAL4 - INSTALLING THE 244X ONT

4 Installing the 244x ONT In this Chapter:- 4.1 Preparing for Installation- 4.2 Installing the UPS- 4.3 Mounting the 244x Enclosure- 4.4 Grounding the 244x ONT- 4.5 Connecting the Fiber Optic Cable- 4.6 Mounting the Electronics Panel to the ONT- 4.7 Inserting the Fiber Optic Cable into the Laser- 4.8 Connecting the Power Cable- 4.9 Securing the Electronics Panel- 4.10 Connecting the Ethernet Cables- 4.11 Connecting the Voice Ports- 4.12 Connecting the HPNA Cable to the 244x ONT- 4.13 Completing the ONT Installation

4.1 Preparing for InstallationThis section contains the following subsections:- 4.1.1 ONT and UPS Site Guidelines- 4.1.2 Preventing Electrostatic Discharge (ESD) Damage- 4.1.3 Weatherproofing the ONT- 4.1.4 Unpacking the ONT



4.1.1 ONT and UPS Site Guidelines

4.1.1.1 244x ONTThe Calix 244x Series GPON ONT uses a robust housing to protect the enclosed networking electronics. The product design accommo-dates a wide range of environmental extremes, including harsh winters, hot summers and associated snow and rain (refer to Weather-proofing the ONT for information about protecting the ONT from corrosion in coastal regions). However, as with all electronic equipment, there are operational limitations. Specifically, when in use, temperatures inside the ONT enclosure must remain between -40C to +55C (-13F to 131F), and relative humidity must be between 10% and 90% without condensation.Before the ONT is installed at a residence or business, consideration of an appropriate physical location is important: • The ONT must be mounted in an area with access to existing customer wiring and grounding. It must be located within 25 feet (or

100 feet with optional cable) of the indoor UPS.• Ideally, the ONT should be mounted on the side of the structure in a location where it is shaded from direct summer sunlight which

in some locations could raise the internal temperatures beyond the upper range of operating parameters. • Avoid locating the ONT on dark colored walls with southern exposures where thermal loads in direct summer sunlight can easily

exceed 150F. • If the ONT must be mounted on a dark colored wall, allow a gap of at least half an inch between the ONT and the wall, allowing air

to flow behind the ONT and cool the unit. A screen should be placed around the gap in such a way as to prevent bees, wasps and hornets from building a nest behind the ONT that would obstruct air flow.

• The ONT should be located in an area where it is out of direct water spray from irrigation or sprinkler system.

4.1.1.2 UPS The UPS must be indoors and within six feet of an AC outlet. The UPS must also be located within 25 feet (or 100 feet with optional cable) of the NID. This distance also includes the cable management.



4.1.2 Preventing Electrostatic Discharge (ESD) Damage

To prevent ESD damage to the ONT, observe the following guidelines:• Always wear an ESD-preventive wrist strap when handling the ONT and blades, ensuring that the strap makes ample contact with

your skin.

Remember that the wrist strap only protects the ONT from ESD voltages present on the body. ESD voltages can also be present on clothing and can cause ESD damage to the ONT.• Ground yourself by touching the metal part of the chassis if you do not have a wrist strap available.

4.1.3 Weatherproofing the ONTWhen required, apply Dow Corning® High-Vacuum Grease to the RJ -45 connectors used by the Ethernet cables and the RJ-11 connec-tors used to connect the station wire to the voice ports. This grease keeps all moisture out of the RJ-45 and RJ-11 connectors and pre-vents the connections from being shorted out by conductive corrosive solutions. Dow Corning® High-Vacuum Grease can be purchased from Calix.For grease application instructions refer to Connecting the Ethernet Cables and Connecting the Voice Ports.

If the ONT is touched or handled improperly ESD damage to the ONT can occur. Static voltages as low as 30 volts can dam-age circuitry. Make sure to observe all standard anti-static procedures when handling electronic equipment and components.

Note: Periodically check to make sure that the resistance value of the antistatic wrist strap is between 1 and 10 megohms.



4.1.4 Unpacking the ONT

Unpack the ONT using the following steps:

1. Inspect all packing containers. If any damage or other signs of mishandling is evident, immediately inform both the carrier and Occam Networks before proceeding.

2. Carefully remove the ONT from the container.

3. Examine the ONT and cables for signs of damage or other mishandling.

4. Check the packing list to verify receipt of all components. Contact Calix immediately to report any discrepancies.

4.2 Installing the UPSFollow the installation instructions that came with the UPS.

The distance between the UPS and the ONT is limited to 50 feet if the wire gauge used for the 12 V DC battery is 18 AWG or 100 feet if the power leads are 16 AWG. Install the loose cable with the colors in the same order from left to right based on the color codes of the wire used. Use the lower gauge (thicker wire) for the first two (left most terminals called out Red/Black below) terminals since these carry the power.

Static voltages as low as 30 volts can damage circuitry. Make sure to observe all standard anti-static procedures when han-dling electronic equipment and components.

Note: A pre-terminated power cable is available from Calix. You may also use an appropriate loose wire that is able to tolerate the exposure to external environment (for example, one that is UV resistant). A power connector is available from Calix as well, either individually or in lots of 100.



4.3 Mounting the 244x EnclosureUse the following steps to mount the 244x enclosure:

1. Remove the 244x ONT Enclosure from its shipping container and packaging.

2. Remove the outer door.

3. Using two screws of sufficient length, securely fasten the enclosure to the side of the building as shown in Figure 4-1. The screw holes are 9 inches apart. The holes on the 244x enclosure allow horizontal adjustment at the top and vertical adjustment at the bot-tom.

Figure 4-1: Mounting the 244x ONT Enclosure on a Wall



4.4 Grounding the 244x ONT

Calix recommends that you ground the ONT with an 8 AWG solid ground wire to the best earth ground available at the site according to standard telecommunications grounding practices with the goal of obtaining a ground resistance of 5 Ohms or less. You can ground the ONT directly to the home electrical ground, properly grounded metallic water pipe or to a solid copper ground rod at least six feet long in close proximity to the ONT.If you use a separate ONT grounding rod, the home must have a separate earth ground. Resistance between the home earth ground and ONT ground rod must be less than 25 Ohms.Use the following steps to ground the 244x ONT:

1. Assure power is disconnected from the chassis.

2. Locate the grounding lug, as shown in Figure 4-2.

Figure 4-2: Grounding Lug

For proper operation and equipment protection, the 244x ONT must be properly grounded according to NEC 830.100(D). If you are using shielded fiber optic subscriber drop cable, refer to section 4.5.1 Grounding a Shielded Fiber Optic Cable for information about how to ground the shield.



3. Connect an 8 AWG solid ground wire. Route the ground wire through the second access port from the left, as shown in Figure 4-3.

Figure 4-3: 244x ONT Chassis Grounded

4. According to local practice, connect other end of ground cable with a screw, washer and lock washer to ensure a reliable ground connection.

5. Dress the ground cable run with cable ties or clamps and verify tight connection on screws, nuts and connectors.



4.4.1 Ferrite ClampA ferrite clamp is shipped with some versions of the 244x Series GPON ONTs, tie wrapped to the ONT plastic inner enclosure. Remove this clamp from the tie wraps and attach it around the ground wire, inside the ONT enclosure and next to where the ground wire attaches to the ground connection inside the enclosure as shown in Figure 4-4. This clamp is only required when it is shipped with a 2400 Series GPON ONT.The purpose of this clamp is to maintain Class B emission levels and is not required on most 244x Series GPON ONTs.

Figure 4-4: Ferrite Clamp Attached to Ground Wire



4.5 Connecting the Fiber Optic Cable

Use the following steps to connect the fiber optic cable:

1. Route the drop fiber through the first access port from the left as shown in Figure 4-5.

2. Prepare the fiber, leaving 60 inches of buffer tube.

3. Secure the fiber to the ONT with the strength members (yarn-like material beneath the outermost jacket).

Figure 4-5: Routing Drop Fiber into the Chassis

When using shielded fiber optic subscriber drop cable, it is necessary to properly ground the shield as it comes out of the cable sheathing in the ONT. Since the metallic shielding provides an opportunity for lightning ingress, proper grounding is especially critical for both the safety of the 244x ONT's electrical components and of the personnel maintaining it. Refer to section 4.5.1 Grounding a Shielded Fiber Optic Cable.

To avoid damage to your fiber optic cables, do not bend the cables to a radius smaller than 1.5 inches (38 mm). Bending the cable farther than its minimum bend radius may result in increased attenuation or broken fibers.



4. Secure the fiber and the ground wire to the ONT with cable ties as shown in Figure 4-6.

Figure 4-6: Securing the Fiber to the Chassis with Cable Ties

5. Mark the buffer tube where it enters the fiber tray as shown in Figure 4-7.

Figure 4-7: Marking the Buffer Tube



6. Place a mark 14” from the connector end on a 1 meter long 3 mm jacketed fiber jumper as shown in Figure 4-8.

Figure 4-8: Marking 3 mm Jacketed Fiber Jumper

7. Strip the remaining jacket as shown in Figure 4-9.

Figure 4-9: Stripping Jacketed Fiber Jumper



8. Remove the fiber tray from the rear of the ONT chassis, as shown in Figure 4-10, and secure the drop fiber and pigtail to the fiber tray with cable ties.

Figure 4-10: Removing Fiber Tray from the Chassis



9. Reinstall the fiber tray and remove 24” of the buffer tube from the drop fiber. Wrap the buffer tube in the fiber tray so that the end is at in center at the bottom as shown in Figure 4-11. Store spare drop fibers in the fiber tray.

Figure 4-11: Wrapping Buffer Tube in the Fiber Tray. Splice the fiber as shown in Figure 4-12.

Figure 4-12: Splicing the Fiber



10. Place the sleeve in the tray as shown in Figure 4-13.

Figure 4-13: Placing the Sleeve in the Fiber Tray

Dress the remaining fiber in the tray as shown in Figure 4-14. If the customer port has been enabled, check the light level.

Figure 4-14: Dressing the Remaining Fiber in Fiber Tray



4.5.1 Grounding a Shielded Fiber Optic CableUse the following steps to ground a shielded fiber optic cable:

1. Slip the inner clamp under the composite cable’s metal sheath, as shown in Figure 4-15.

2. Slide the spike over the stud that protrudes from the inner clamp.

3. Secure the spike to the inner clamp with a nut.

Figure 4-15: Clamp on Shielded Fiber Optic Cable

4. Secure the clamp to the fiber optic cable with electrical tape, taking care not to cover the clamp stud and nut.



5. Attach the clamp to the ground stud so that the clamp stud faces to the front of the chassis. Loosen the ground bracket so you have enough clearance to place the clamp stud behind the bracket. Make sure that you tighten the ground bracket again when you are done and that it is in the correct position, using the lines on the ONT chassis as a guide.

6. Attach the clamp stud to the grounding bracket with a nut. Continue to install the fiber cable, as described in Connecting the Fiber Optic Cable. If the clamp stud protrudes out very far, it may prevent the ONT electronics panel from closing securely. You may need to attach the grounding lug to the end of the clamp stud with two nuts.

4.6 Mounting the Electronics Panel to the ONTMount the electronics panel to the ONT as shown in Figure 4-16.

Figure 4-16: Mounting the Electronics Panel to the ONT



4.7 Inserting the Fiber Optic Cable into the LaserUse the following steps to insert the fiber optic cable into the laser:

1. Insert the fiber optic cable into the laser and route it through the chassis’ fiber management brackets as shown in Figure 4-17.

Figure 4-17: Route Fiber through Management Brackets

Note: Keep the lasers and fiber optic cables clean and dust-free to prevent damage and maintain high signal accuracy.



2. Close the electronics panel, confirming that the fiber optic cable does not bind (Figure 4-18). Secure the inside panel on the 244x ONT chassis with tamper proof screwdriver.

Figure 4-18: Closed Electronics Panel



4.8 Connecting the Power CableThe power cable is an 18 AWG 8 wire cable terminated in a connector for the 244x ONT. It is blunt cut for ease of installation through the wall to the UPS Power System.Use the following steps to connect the UPS power cable:

1. Locate the power cable and insert the connector on the end of the power cable to the power connector. It will only fit in one direc-tion.

Figure 4-19: Power Connector on 244x ONT

2. Secure the power cable to the brackets on the electronics panel with cable ties.

Note: The power cable is routed through the second access port from the left, the same as the ground wire earlier.

Do NOT plug the power connector into the UPS power supply at this time.



4.9 Securing the Electronics PanelSecure the electronics panel on the 244x ONT chassis with tamper proof screwdriver.

4.10 Connecting the Ethernet CablesConnect the Ethernet cables to the RJ-45 connectors on the ONT board. These Ethernet cables, which have probably been pulled through a hole in the house wall, must be rated CAT5e and terminate in RJ-45s with the proper color code.Use the following steps to connect the Ethernet cables:

1. Locate the four RJ-45 connectors for Ethernet interfaces as shown in Figure 4-20.

Figure 4-20: Ethernet LAN Interfaces

2. Insert the Ethernet cables through the first access hole from the right and connect them to the RJ-45 connectors.If you are applying Dow Corning® High-Vacuum Grease to weatherproof the ONT, as described in Weatherproofing the ONT, inject a small amount of about 1/4 inch diameter into each connector receptacle. Slowly insert an Ethernet cable, allowing the grease to well up and fill all the space in the RJ-45 connector and around the Ethernet cable. Make sure to remove any excess grease on the top panel.



4.11 Connecting the Voice PortsYou can terminate the internal wiring in a modular jack or use the enclosed RJ-11 jumpers by stripping the internal phone wire and plac-ing it under a screw terminal.

4.11.1 Inserting the RJ-11 JumpersUse the following steps to insert the RJ-11 jumpers:

1. Locate the two RJ-11 jumpers, as shown in Figure 4-21.

Figure 4-21: RJ-11

2. Insert the RJ-11 jumpers on to the front inside panel of the 244x ONT.

3. Insert the station cable through the second access port from the right. Strip the cables and place the appropriate wires under the screw terminals to the RJ-11 jumpers.

4. If you are applying Dow Corning® High-Vacuum Grease to weatherproof the ONT, as described in section 4.1.3 Weatherproofing the ONT, inject a small amount of about 1/4 inch diameter into each connector receptacle.

5.1 ONT Safety and Compliance Information

5.1.1 ONT Safety Warnings and CautionsThe following information provides safety precautions to follow when installing and operating this equipment. This equipment is to be installed and maintained by qualified service personnel only.

This equipment must be provided with an additional means of disconnecting the electrical supply to ensure the proper overcurrent protection of the equipment, and the safety of the persons servicing and operating this equip-ment. For AC-powered equipment, the customer must provide a 20 Ampere listed circuit breaker on the branch cir-cuit. As an alternative in case of emergency, the plug to the receptacles for the electric main can be used to shut off the power; the receptacles for the power main must be located so that they are visible and easily reached. Ensure that all power cords are disconnected before performing service on this equipment. For DC-powered equipment, a listed circuit breaker or other appropriate disconnect device must be provided as part of the building installation.

To reduce the risk of fire, replace fuses with the same type and rating as those originally installed. There are no user-replaceable fuses on Calix Optical Network Terminals.



Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.

The subscriber interfaces for the network terminals are not to be connected to a telecommunications network volt-age (TNV) circuit. External service connections must be made through Listed telecommunications network equip-ment collocated in the same building.

Protection of the Telecommunications Network during a Lightning event or Overvoltage event from power line crosses relies on the protective earthing of this product. The protective earthing terminal located in the outer enclo-sure MUST be permanently connected to a reliable ground. Use 8 to 10 AWG Cu grounding wire. The module's tamper resistant grounding screw shall be tightened down prior to applying power

This product has components that are sensitive to damage from electrostatic discharge (ESD). ESD occurs when electronic printed circuit cards are handled improperly and can result in intermittent or complete failures. Refer to Preventing Electrostatic Discharge Damage for ESD handling procedures.

ONTs are acceptable for connection to IT systems. A single ground lug is incorporated in the shelf unit to perma-nently ground this equipment at the installation site. Use 8 to 10 AWG Cu grounding wire.

This equipment must be provided with adequate ventilation for proper cooling. Do not block ventilation and cool-ing ports with other equipment. The GPON Optical Network Terminal (ONT) modules, 244x ONT product family, should be operated in a maximum ambient temperature of +65°C (+149° F) as measured 0.5" from front center of module.



5.1.2 FCC Notice (GPON ONT)This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installa-tion. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equip-ment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:• Reorient or relocate the receiving antenna.• Increase the separation between the equipment and receiver.• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.• Consult the dealer or an experienced radio/TV technician for help.

5.1.2.1 Adding the Ferrite-to-Earth GroundA ferrite clamp is shipped with some versions of the 2400 Series GPON ONTs, tie wrapped to the ONT inner enclosure. Remove this clamp from and attach it around the ground wire, inside the ONT enclosure next to where the ground wire attaches to the ground con-nection inside the enclosure. This is shown in Figure 5-25. This clamp is only required if it is shipped with a 2400 series GPON ONT.The purpose of this clamp is to maintain Class B emission levels and is not required on most 244x series GPON ONTs.

5.2 Optical Warnings and CautionsCalix lasers are certified to be Class 1 laser-safe, as defined by the U.S. Department of Health and Human Services, 21 CFR 1040.10 and the International Electrotechnical Commission, IEC 60825. Calix blades that employ laser components have their laser emission continuously monitored and adjusted by internal electro-optical circuits. There are no user adjustments or controls, and maintenance is not needed.

Laser Safety Notice:

Performance or procedures other than those specified herein may result in hazardous radiation exposure. Do not use optical instruments to view the laser output: this will increase the risk of eye damage.

To reduce the risk of optical system failure, know and follow optical inspection and cleaning procedures. Always clean and inspect optical connectors before making connections. Always keep protective caps on connector fer-rules and protective plugs on bulkhead connectors.



5.3 Preventing Electrostatic Discharge DamageMany B6 and ONT components are sensitive to damage from electrostatic discharge (ESD). ESD occurs when electronic printed circuit cards are handled improperly and can result in intermittent or complete failures.

• Ensure that the B6 and ONT chassis are electrically connected to earth ground.• To safely channel unwanted ESD voltages to ground, wear an ESD-preventive wrist strap and ensure that it makes good skin contact.

Connect the clip to an unpainted surface at the rear of the chassis frame or if the rear of the chassis frame is not accessible, then remove the front bezel and attach the ESD strap to either of the ball studs used to secure the bezel in place. To properly guard against ESD damage and shocks, the cord and wrist strap must operate effectively.

• Always wear an ESD-preventive wrist strap when handling the B6 chassis and blades, ensuring that the strap makes ample contact with your skin. A non-insulated grounding banana jack is located on the upper right of the B6 chassis.

• If no wrist strap is available, ground yourself by touching an unpainted metal part of the chassis.

5.4 CE Mark QualificationThe Calix 244x Series GPON ONT has been tested to EN300386 as part of CE Mark qualification for Europe. The GPON ONT can be installed in Europe with CE Mark as long as a dedicated CE Certified Power supply or UPS provides the DC Power to the ONT. Further information on the CE testing or GPON ONT installation can be provided with request to Calix Customer Support.

Always follow ESD prevention procedures when handling the B6 and ONT.

For both equipment protection and user safety, periodically check the resistance value of the antistatic strap. The measurement should range from 1 to 10 Megaohm (Mohm).
