Power Supply Modules
The Firepower 4100 security appliance 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, PSU-1 and PSU-2.
Note The system power requirements are lower than the power supply module capabilities. See
Specifications, on page 34
Make sure that one power supply module is always active.
