Installing The Module - Allied Telesyn AT-BSTACK1 Guía De Instalación Rápida

Installing the Module

To install the module, perform the following procedure:
1. Power off the switch by disconnecting the AC power cord from the switch.
If the switch is connected to a redundant power unit (RPU), disconnect the
DC cable connection to the switch.
Caution
The switch must be powered off before installing or replacing the
module. Installing the module with the switch powered on can damage
the module.
2. Using a flathead screwdriver, remove the faceplate from the lower left
expansion slot (slot B) on the rear panel of the switch, as shown in Figure 1.
Caution
The AT-BSTACK1 Stacking Module must be installed in the lower left
expansion slot (slot B). Installing the module in any other expansion slot
can damage the module.
Note
Keep the original faceplate for future use. If you should remove the
module, replace the faceplate to prevent dust and debris from entering
the unit and to maintain proper air flow.
Caution
Be sure to wear an anti-static wristband before performing the next
step. This is to prevent damaging the AT-BSTACK1 module.
