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.

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.
