4.3.2 Removing and Replacing the AT Bus Expansion Kit
The 2T-VC220-IP AT bus expansion kit consists of the transmit module installed in the
AlphaServer 1000A, the receive module installed in the ISA bus expansion chassis, and a 2-
meter cable that connects the two modules.
Perform the following procedure to remove the receive module from the ISA bus expansion
chassis:
1. Remove power from the ISA bus expansion chassis by pressing the On/Off switch on the
front of the ISA bus expansion chassis.
2. Remove the screws that secure the ISA bus expansion chassis to the front rails and extend
the ISA bus expansion chassis on the slides.
3. Remove the screws that secure the top cover and remove the top cover from the ISA bus
expansion chassis.
4. Disconnect the cable from the receive module.
5. Remove the hold-down bar from across the top of the modules in the ISA bus expansion
chassis.
6. Remove the screw that secures the receive module to the rear bulkhead of the ISA bus
expansion chassis.
7. Remove the receive module from the ISA bus expansion chassis.
To replace the receive module in the ISA bus expansion chassis, reverse steps 1 through 7 of
the removal procedure. Ensure that the jumpers on the new receive module are set to match
the jumpers on the receive module being replaced.
