Installing the Switch

Installing an Expansion Module

This section contains the instructions for installing an optional

expansion module in a switch. For information on cabling

specifications for the expansion modules, refer to the section

Expansion Modules on page 2-33.

To install an expansion module, perform the following steps:

1. Disconnect the switch’s power cord, if attached.

Caution

Be sure to disconnect the power cord to the switch before installing

an expansion module. If the switch is connected to a redundant

power supply (RPS) unit, disconnect the switch from the RPS unit as

well. Installing the expansion module with the switch powered ON

can damage the module.

2. Remove a blank faceplate from one of the expansion slots on the

front of the switch by unscrewing the faceplates two captive

screws. Refer to Figure 3-15. Do not remove the blank faceplate if

you are not installing an expansion module in the slot.

Figure 3-15 Removing the Blank Panel

If you are installing only one expansion module in the switch,

install the module in slot A. While the module will work in slot

B with slot A empty, the port numbering assignments will

change if you later install a module in slot A. This could affect

VLAN memberships on the switch, and this could require you

to adjust your VLAN configurations.
