Step 9
Replace the terminal block plastic cover. The plastic cover is slotted and keyed to fit correctly over the terminal block.
This cover should always be in place when power is applied to the terminals.

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,
on page 7
for a description of the the LEDs.
Secure the Power Cord on the AC Power Supply Module
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.
The black tie wrap is used with the Flextronics power supply module and the off-white tie wrap is used with
the Artesyn power supply module. The black clamp works with both. See the figures below.
