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.

and replacing the power supply module.
• See Connect the DC Power Supply Module, on page 72 for the procedure for connecting the DC
power supply module.

HVDC power supply module.

Fan Modules
The Firepower 9300 requires four fan modules, which are hot-swappable. They are installed in the rear of the
chassis. When you remove a fan module, make sure you replace it quickly to avoid overheating the system.
The fan modules are numbered left to right, for example, FAN-1, FAN-2, FAN-3, and FAN-4.
The fan modules have the following LEDs:
• Amber, flashing—Fan failure.
• Green—Fan running normally.
For More Information
See Remove and Replace the Fan Module, on page 75 for the procedure for removing and replacing fan
modules.
Supported SFP/SFP+ and QSFP Transceivers
The SFP/SFP+ and QSFP transceivers are bidirectional devices with a transmitter and receiver in the same
physical package. They are a hot-swappable optical or electrical (copper) interface that plugs into the
SFP/SFP+/QSFP ports on the fixed ports and the network module ports, and provides Ethernet connectivity.
