Warning
Do not touch the power supply when the power cord is connected. For systems with a
power switch, line voltages are present within the power supply even when the power switch is off
and the power cord is connected. For systems without a power switch, line voltages are present
within the power supply when the power cord is connected.
Take these steps:
Step 1
Power OFF the access server.
Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units.
Warning
Before opening the chassis, disconnect the telephone-network cables to avoid contact
with telephone-network voltages.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning
activity.
Step 2
Remove all cables from the rear panel of the access server.
Step 3
Place the access server so that the front panel is facing you.
Step 4
Remove the three screws located on the top cover of the chassis.
