You must remove only one fan module at a time for replacement from the rear panel of
the chassis. The switch continues to operate for a limited period of time (30 seconds)
during the replacement of the fan module without thermal shutdown.
NOTE: Both the fan modules must be installed for optimal functioning of
the switch.
For EX4300 switches except EX4300-48MP and EX4300-48MP-S switches, the fan
modules are available in two models that have different airflow directions—back-to-front
(air enters through the back of the switch), indicated by label
front-to-back (air exhausts through the back of the switch), indicated by label
(AFO) . For EX4300-48MP and EX4300-48MP-S switches, the fan module is available
in one model that has front-to-back (air exhausts through the back of the switch),
indicated by label
