grounded bare rack.
Installing the Power Supply Module in the Switch
Step 1
We recommend that power be off at the AC or DC circuits. Locate the circuit breakers, turn them OFF,
and tape them in the OFF position.
Note
If the power is not off at the AC or DC circuit breaker, do not touch the power-input terminal.
Step 2
Use a Phillips screwdriver to loosen the two captive screws of the blank power supply module and gently
pull it out. See
Figure 3-6
and
Figure 3-7
.
