Extreme heat, cold, or humidity

After removing screws, make sure to store them in a safe place and to identify them with thecorresponding parts.

1.2.1 Assembly Reminders

While assembling the controller, remember the following general points:

Make a note, while disassembling the controller, of the locations and connections of the variouscomponents, cards, and cables. This will make assembly easier.

Take your time, making sure to follow the instructions closely. Many problems can occur fromhurried assembly.

Make sure all cables and connectors are securely fastened.

Make sure cable connectors are properly attached to sockets. Attaching a connector backwardscould cause improper card or component operation.

Before securing components, make sure cables will not be pinched by screws or the componentitself.

When replacing side panels, make sure cables are tucked inside the controllers chassis to avoiddamaging the cables.

Make sure all latches are securely closed.

When assembling the controller, make sure to use the correct screws to secure the variouscomponents, and make sure all screws are securely fastened. Loose screws can cause shortcircuits, resulting in heat, smoke, and fire.

Make sure the correct screws are used to secure all controller parts. Using the incorrect screwscould damage the threads or the head of the screws, resulting in improper seating of the screw.

1.2.2 Protecting the System from Electrostatic Discharge (ESD)

Electrostatic discharges can cause serious damage to controller components and circuitry. Static

electricity can be generated in many, seemingly innocent, ways such as walking across a vinyl flooror rubbing your hand on a carpeted area. With this in mind, it is important to protect the controller

from the dangers of static electricity while you perform the removal and installation procedures in this

manual. The following information addresses effective grounding techniques and protecting

components and drives from ESD.

3.1.6 Assembly Reminders

While assembling the controller, remember the following general points:

Make a note, while disassembling the controller, of the locations and connections of the variouscomponents, cards, and cables. This will make assembly easier.

Take your time, making sure to follow the instructions closely. Many problems can occur fromhurried assembly.

Make sure all cables and connectors are securely fastened.

Make sure cable connectors are properly attached to sockets.

Before securing an FRU or other components, make sure cables will not be pinched by screws orthe FRU.

When replacing bracket cover, make sure cables are tucked inside the controllers chassis to avoiddamaging the cables.

Make sure all latches are securely closed.

When assembling the controller, make sure to use the correct screws to secure the variouscomponents, and make sure all screws are securely fastened. Loose screws can cause short

circuits, resulting in heat, smoke, and fire.

Make sure the correct screws are used to secure all FRUs and other controller parts. Using theincorrect screws could damage the threads or the head of the screws, resulting in improper seating

of the screw. Refer Table 3-1 for a listing of screw sizes and quantities for each FRU and

component.
