If the target bay is protected bya blank power filler plate, remove the blank.2.Insert the power supply module into the selected power‐supply bay and gently push it into the slotuntil it latches. Each power supply module has a mechanical guide key to prevent you from inserting themodule incorrectly.3.Connect the power cord to the power supply module and to an appropriate universal grounded ACpower source.4.Make sure that the power supply module’s OK and AC LEDs are green.Removing and Replacing a Fan ModuleThe rear panel of the G8264 has four bays for hot‐swap fan modules. Four active fanmodules are required for redundancy.With active fan modules in all fan bays, if one fan fails, the switch will send an errormessage and continue operation. You can then replace the failed fan withoutpowering off the switch or disrupting switch functions. If a second fan fails, theswitch will send another error message, write a log message to flash memory, andshut down to prevent overheating.For proper airflow when operating the switch with one empty fan bay (anon‐redundant configuration), the empty fan bay must be closed with a blank fanfiller plate.Engage Latch
