Power Supply Modules, On - Cisco Firepower 9300 Hardware Installation Manual

Overview
Power present
DC Power Supply Module
The power switch controls the DC power output. The system input power is +12 V. If the power switch
is off (standby) when input DC (-48 V) is present, the main power is turned off and only +3.3 V standby
is available for the system. If the power switch position is on (active) when input DC (-48 V) is present,
the main power is turned on as well as +3.3 V standby, and the system is running.
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.
The following table describes the DC power supply LEDs.

HVDC Power Supply Module
The HVDC power supply modules run at 2500 W for +240 to +380 V DC. 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. The power supply entry module is not removable. This is the module that you plug the
power cords into.
