Installing or replacing a fan module
The RackSwitch G8264CS contains up to four hot-swap fan modules. Three fan
modules are required for normal operation.
The switch continues to operate when there is one failed fan module. If one fan
fails, the switch sends an error message. If a second fan fails, the switch sends an
error message, writes a failure log to flash memory, and shuts down.
Each fan module has a green LED that is visible from the rear panel. The LED
shows the status of the fan module, as follows:
v LED is lit: Fans are operational.
v LED is off: Switch unit has no power.
v LED flashes: Fan speed has failed. Replace the fan module.
