Power Supply Modules - Cisco Firepower 2120 Hardware Installation Manual

Overview

Power Supply Modules

The Firepower 2110 and 2120 have one fixed AC power supply. If the power supply fails, you must send
your Firepower 2110 or 2120 for RMA.
The Firepower 2130 and 2140 support two AC power supply modules so that dual power supply redundancy
protection is available. The Firepower 2130 ships with one AC power supply and the Firepower 2140 ships
with two AC power supplies. You can also install DC power supply modules rather than AC power on the
2130 and 2140. Facing the back of the chassis, the power supply modules are numbered left to right, for
example, PSU1 and PSU2.
You CANNOT mix AC and DC power supply modules in the chassis.
Note
Note The power supply module is hot swappable.
The system power requirements are lower than the power supply module capabilities. See the following
Note
table.
Make sure that one power supply module is always active.
Attention
AC Power Supply
The dual power supplies can supply up to 800W power across the input voltage range. The load is shared
when both power supply modules are plugged in and running at the same time.
The system does not consume more than the capacity of one power supply module, so it will always
Note
operate in full redundancy mode (2130 and 2140 only) when two power supply modules are installed.
