G8264 Installation Guide
To replace a hot‐swap power supply module, complete the following steps:
The rear panel of the G8264 has four bays for hot‐swap fan modules. Four active fan
modules are required for redundancy.
With active fan modules in all fan bays, if one fan fails, the switch will send an error
message and continue operation. You can then replace the failed fan without
powering off the switch or disrupting switch functions. If a second fan fails, the
switch will send another error message, write a log message to flash memory, and
shut down to prevent overheating.
For proper airflow when operating the switch with one empty fan bay (a
non‐redundant configuration), the empty fan bay must be closed with a blank fan
filler plate.
