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

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.

Warning

Use appropriate ESD procedures when inserting the transceiver. Avoid touching the contacts at the rear, and

keep the contacts and ports free of dust and dirt. Keep unused transceivers in the ESD packing that they were

shipped in. The following figure shows a sample SFP transceiver.
