Cisco Firepower 4110 Hardware Installation Guide

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 9 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.
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.
Safety Warnings
Take note of the following warnings:
Statement 1030—Equipment Installation
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning
Statement 1073—No User-Serviceable Parts
There are no serviceable parts inside. To avoid risk of electric shock, do not open.
Warning
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.
