PreparationBeforeinstallingtheMiniGBIC,proceedasfollows:

1. BeforeremovingtheMiniGBICfromtheantistaticpackaging,itisrecommendedthatyouuseanantistaticwriststrap(notsupplied)topreventdamagefromstatic

use

the

refer

to

the

instructions

provided

with

your

antistaticwriststrap.

2. RemovetheMiniGBICfromitspackaging.

3. IfthereisaprotectivedustcoverintheMiniGBICconnector,donotremoveitatthistime.

Warning: Fiber-optic Mini-GBICs use Class 1 lasers. Do not use optical instruments toview the laser output. The use of optical instruments to view laser output increases eyehazard. When viewing the output optical port, power must be removed from the networkadapter.

Advertencia: Los Mini-GBICS de fibra optica usan lasers de clase 1. No se debe usarinstrumentos opticos para ver la potencia laser. El uso de los instrumentos opticos paraver la potencia laser incrementa el riesgo a los ojos. Cuando vean el puerto de la potenciaoptica, la corriente debe ser removida del adaptador de la red.

Warnhinweis:Mini-GBICs mit Fiber-Optik Technologie benutzen Laser der Klasse 1.Benutzen sie keinesfalls optische Hilfsmittel, um die Funktion des Lasers zu berprfen.Solche Hilfsmittel erhhen die Gefahr von Sehschden. Wenn sie den optischen Portberprfen mchten stellen Sie sicher, dass die Komponente von derSpannungsversorgung getrennt ist.

Caution: Carefully follow the instructions in this manual to avoid damaging theMini-GBIC and the device.

The Mini-GBIC and the device are sensitive to static discharges. Use an antistatic wriststrap and observe all static precautions during this procedure. Failure to do so could resultin damage to the Mini-GBIC or the switch. Always leave the Mini-GBIC in the antistatic bagor an equivalent antistatic container when not installed.

Precaucin: Siga las instrucciones del manual para no daar el Mini-GBIC ni del aparato,puesto que son muy sensible a las descargas de electricidad esttica. Utilice la pulsera

antiesttica y tome todas las precauciones necesarias durante este procedimiento. Si nolo hace, podra daar el Mini-GBIC o del aparato. Mientras no est instalado, mantenga elMini-GBIC en su bolsa antiesttica o en cualquier otro recipiente antiesttico.

Caution: Do NOT remove a Mini-GBIC from a slot without releasing the locking tablocated under the front bottom end of the Mini-GBIC. This can damage the Mini-GBIC.

The Mini-GBIC and its host switch are sensitive to static discharges. Use an antistaticwrist strap and observe all static precautions during this procedure. Failure to do so couldresult in damaging the Mini-GBIC or host switch. Always leave the Mini-GBIC in theantistatic bag or an equivalent antistatic container when not installed.

2. (Optional)Ifdesired,changethemanagementswitchusingthesetswitchmovemanagementcommandasdescribedintheSecureStackA2ConfigurationGuide.

ImportantThe following procedures assume that all switches have a clean configuration from manufacturing.When adding a new switch to an already running stack, it is also assumed that the new switch isusing the same firmware image version as other switches in the stack.

Note: Once switch IDs are assigned, they are persistent and will be retained during apower cycle to any or all of the switches.

Important Considerations About Using Clear Config in a Stack

When using the clear configcommand (as described in the SecureStack A2 Configuration Guide)to clear configuration parameters in a stack, it is important to remember the following:

Use clear configto clear config parameters without clearing stack switch IDs. This commandWILL NOT clear stack parameters and avoids the process of re-numbering the stack.

Use clear config allwhen it is necessary to clear all config parameters, including stack switchIDs and switch priority values.

Considerations About Using Clear Config on a Standalone A2 withthe Uplink Ports Configured as Standard Gigabit Ethernet Ports.

When using the clear configcommand (as described in the SecureStack A2 Configuration Guide)to clear configuration parameters on a standalone A2 switch with the uplink ports configured asstandard Ethernet ports (Ethernet mode), it is important to remember the following:

The clear configcommand WILL NOT set the front panel uplink ports back to stack ports.

The clear config allcommand WILL set the front panel uplink ports back to stack ports.

ToconnectaswitchtotheACpowersource,refertoFigure 39andproceedasfollows:

1. PlugthepowercordintotheswitchACpowerconnector.

2. PlugtheotherendofthepowercordintoadedicatedgroundedACoutlet(notshown).Thetypeofpoweroutletandpowercordarecountrydependent.

Note: The power supply in the switch has automatic voltage sensing that allowsconnection to power sources ranging from 100 to 240 VAC.

Note: If you plan to connect all the switches quickly to allow automatic Manager selection,wait until all switches are fully operational before proceeding to the next step.

If you plan to power up each switch and allow it to become fully operational beforeapplying power to the next switch, proceed to the next step.

Caution: To prevent damaging the switch, DO NOT connect a Power overEthernet-compliant Redundant Power System (C2RPS-POE) to the redundant powersupply connector. The switch is only compatible with the SecureStack C2RPS-SYSredundant power supply system.

Precaucin: No conecte una fuente de poder redundante (RPS) SecureStack PoE(C2RPS-POE) al cable de corriente. De lo contrario, el dispositivo puede daarse.
