Step 6 Repeat these steps for the remaining DC input power source wire as applicable.
Step 7 Use a tie wrap so secure the wires to the rack, so that the wires are not pulled from the terminal block.
Step 8 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 9 Verify power supply operation by checking the power supply LED on the front of the chassis. See Front Panel LEDs, on
page 10 for the LED values.
Secure the Power Cord on the 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 2100 security
appliance.

Step 1 Attach the clamp to the tie wrap by holding the clamp with the loop side on the bottom and sliding the tie wrap through
the box-shaped channel above the clamp (see the following figure).
One side of the tie wrap has evenly spaced ridges and the other is smooth. Be sure the ridged side is face up and that you
slide it through the open side of the channel. You will hear a click as the tie slides through—it moves in one direction
only. To remove the tie wrap from the clamp, push the lever on the closed side of the box-shaped channel and slide out
the tie wrap.
