Handling the Module
Caution
The expansion module can easily be damaged by electrostatic discharge.
To prevent electrostatic damage, observe the following guidelines:
"
Wear an anti-static wristband connected to a suitable earth ground
whenever handling the module.
"
Do not remove the module from its packaging until you are ready to
install it.
"
Do not touch any of the module's pins, connectors or components.
"
Hold the module only by its edges or front panel.
"
Store or transport this module only in appropriate anti-static
packaging.
Installing the Module
To install the expansion module, perform the following procedure:
1.
Power off the switch by disconnecting the AC power cord from the switch.
If a redundant power unit (RPU) is present, disconnect its DC cable
connection to the switch.
Caution
The switch must be powered off before installing or replacing any
module. Installing a module with the switch powered on can damage the
module.
2.
Using a flathead screwdriver, remove the faceplate from either the lower
right (slot A) or the lower left (slot B) expansion slot, as shown in Figure 4.
Allied Telesyn recommends installing the module in the lower right
expansion slot (slot A) and reserving the lower left slot for the optional
AT-STACK1 Stacking Module.
Caution
Do not install the expansion module in the upper expansion slot (slot
MGMT). This slot is reserved for the optional AT-BMGMT Management
Module.
