Power Supply Modules
The Firepower 9300 supports two AC, two DC, or two high-voltage DC (HVDC) power supply modules so
that dual power supply redundancy protection is available. Facing the front of the chassis, the power supply
modules are numbered left to right, for example, PSU-1 and PSU-2.
Make sure that one power supply module is always active.
Attention
AC Power Supply Modules
The 220-V power supply modules run at 2500 W for 200 to 240 V AC. The load is shared when both
power supply modules are plugged in and running at the same time. The power supply modules support
hot swapping. The power supply entry module is not removable. This is the module that you plug the
power cords into.
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.
