Power Supply Modules

The Firepower 4100 supports two AC or DC power supply modules so that dual power supply redundancy
protection is available. Facing the back of the chassis, the power supply modules are numbered left to right,
for example, PSU1 and PSU2.
Note
Do not mix AC and DC power supply modules in one chassis.
Note
After removing power from the chassis either by moving the power switch to OFF or unplugging the power
cord, wait at least 10 seconds before turning power back ON.
Attention
Make sure that one power supply module is always active.
See Remove and Replace the Power Supply Module, on page 61
the power supply module.
AC Power Supply
The power supplies can supply up to 1100-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. The power supply modules are
hot-swappable.
