Power Supply Modules
The Firepower 2110 and 2120 have one fixed AC power supply that is not field-replaceable. 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 instead of 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.
The power supply module is hot-swappable.
See Product ID Numbers, on page 30 for a list of the PIDs associated with the 2100 series power supply
modules.
You cannot mix AC and DC power supply modules in the chassis.
Note
After removing power from the chassis by unplugging the power cord, wait at least 10 seconds before turning
power back ON.
Note
Make sure that one power supply module is always active.
Attention
The system power requirements are lower than the power supply module capabilities. See the following table.
Note
AC Power Supply
The dual power supplies can supply up to 800-W power across the input voltage range. The load is shared
when both power supply modules are plugged in and running at the same time.
