Rack-Mount the Firepower 4100
This procedure describes how to install the Firepower 4100 in a rack using the rack kit from the accessory kit
that shipped with the chassis.
Before You Begin
You need the following to install the Firepower 4100 in a rack (4-post EIA-310-D rack):
• #1 Phillips Head screwdriver
• Firepower 4100 accessory kit that contains the slide rails, mounting ears, and screws

Rack-Mount the Firepower 4100
Slide rail assemblies work with four-post racks and cabinets with square slots, round 7.1mm holes and 10-32
threaded holes on the rack post front. The slide rail works with front to back spacing of rack posts from 24 to
36 inches.
Step 1
Attach a rack mount bracket to each side of the chassis using six 8-32 x .375" countersink Phillip head screws provided
in the accessory kit.

Attach the inner rails to the sides of the chassis:
a) Remove the inner rails from the slide rail assemblies.
b) Align an inner rail with one side of the chassis so that the three keyed slots in the rail align with the three pegs on
the side of the chassis.
c) Set the keyed slots over the pegs, and then slide the rail toward the front to lock it in place on the pegs. The rear key
slot has a metal clip that locks over the peg.
d) Secure the inner rail to the side of the chassis using one M3X6mm screw.

Open the front securing plate on both slide-rail assemblies. The front end of the slide-rail assembly has a spring-loaded
securing plate that must be open before you can insert the mounting pegs into the rack-post holes.
On the outside of the assembly, push the green arrow button toward the rear to open the securing plate.

Install the slide rails into the rack:
a) Align one slide-rail assembly front end with the front rack-post holes that you want to use.
The slide rail front-end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes
from the outside-front.
The rack post must be between the mounting pegs and the open securing
plate.
b) Push the mounting pegs into the rack-post holes from the outside-front.
c) Press the securing plate release button marked 'PUSH.' The spring-loaded securing plate closes to lock the pegs in
place.
d) Adjust the slide-rail length, and then push the rear mounting pegs into the corresponding rear rack-post holes. The
slide rail must be level front-to-rear.
The rear mounting pegs enter the rear rack-post holes from the inside of the rack post.
Note
e) Attach the second slide-rail assembly to the opposite side of the rack. Make sure that the two slide-rail assemblies
are at the same height with each other and are level front-to-back.
f) Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stops and lock in place.
Step 5
Insert the chassis into the slide rails.
a) Align the rear of the inner rails that are attached to the chassis sides with the front ends of the empty slide rails on
the rack.
b) Push the inner rails into the slide rails on the rack until they stop at the internal stops.

c) Slide the release clip toward the rear on both inner rails, and then continue pushing the chassis into the rack until the
mounting brackets meet the front of the slide rail.

Statement 1046—Installing or Replacing the Unit
When installing or replacing the unit, the ground connection must always be made first and disconnected
last.

Step 7
Grounding the chassis is required, even if the rack is already grounded. A grounding pad with two threaded
M4 holes is provided on the chassis for attaching a grounding lug. The ground lug must be NRTL-listed.
In addition, a copper conductor (wires) must be used and the copper conductor must comply with NEC
code for ampacity.
Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding
cable.
Insert the stripped end of the grounding cable into the open end of the grounding lug.
Use the crimping tool to secure the grounding cable in the grounding lug.
Remove the adhesive label from the grounding pad on the chassis.
Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4
screws with washers through the holes in the grounding lug and into the grounding pad.
Make sure that the lug and cable do not interfere with other equipment.
Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure
adequate earth ground.
Connect Cables, Turn on Power, and Verify Connectivity
After rack mounting the Firepower 4100 series security appliance, follow these steps to connect cables, turn
on power, and verify connectivity.
Step 1
Connect the console port.
Using a serial console cable, connect a computer or terminal server to the RJ-45 serial console port (baud rate is 9600)
so that you can use the CLI to initially set up the Firepower 4100.
Step 2
Connect the management interface.
Install the 1 Gigabit Ethernet transceiver that was provided in the Firepower 4100 accessory kit in the Management port,
and then using an Ethernet cable, connect a management computer directly to the transceiver.

Flip the SFP+ over to connect in the upper
ports.
Step 3
Install the SFP/SFP+ transceivers.
Install SFP/SFP+/ transceivers in the Ethernet network interfaces in the fixed ports or in the network modules you have
installed taking care not to touch the contacts in the rear.
Flip the SFP+ over to connect in the upper ports. The SFP+ connects in the normal way in the lower ports.
The sockets on the upper row face up and the sockets on the lower row face down.
Use appropriate electrostatic discharge (ESD) procedures when inserting the transceiver. Avoid touching the
contacts at the rear, and keep the contacts and ports free of dust and dirt. Store unused SPFs in their ESD
packaging.
Warning
Do not force an SFP transceiver into a socket. This can jam the transceiver and can cause permanent damage
to the transceiver, the chassis, or both.
Connect the Ethernet interfaces.
Use the proper cable to connect the SFP/SFP+ transceivers in the fixed ports or in the network modules you have installed.
