Removing and Replacing a Fan Module
The rear panel of the NE1064TO has five bays for hot-swap fan modules. Five 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.
Removing the Fan Module
To remove a hot-swap fan module, complete the following steps:
1.
Loosen the retainer screw.
2.
Grasp the extractor handle and gently pull the fan module from the slot.
Attention:
If the inlet air temperature is above 35°C (95°F) while the switch is in
operation, replace the fan module within five minutes to avoid overheating the
switch.
Note:
The fan module illustration is used as an example. The actual fan module
differs depending on the switch model.
To return the component to customer service for replacement, see
“Getting Help and Technical Assistance“

information that is necessary to return a component. After you remove the
