Figure 10: Replace the Plastic Cover
Step 10 Set the DC disconnect switch in the circuit to ON. In a system with multiple power supplies, connect each power supply
to a separate DC power source. In the event of a power source failure, if the second source is still available, it can
maintain system operation.
Step 11 Verify power supply operation by checking the power supply LED on the front of the chassis. See Front Panel LEDs
for a description of the LEDs.

Tie Wrap and Clamp
To secure the power supply module against accidental removal and thus prevent disrupting system
performance, use the tie wrap and clamp provided in the accessories kit that ships with your Firepower
4100. There are two different tie wrap and clamp combinations to be used with either the Flextronics or
Artesyn power supply module.
To verify which power supply module you have, look at the vendor name on the top of the power supply
module. If you cannot remove the power supply module, you can count the number of full hexagonal
vent holes on the front of the power supply module in the row directly next to the word 'FAIL.' Flextronics
has five holes and Artesyn has four holes.
