Fan module installation
The fan modules are field replaceable. Module slot 1 is on the left side of the switch; module slot 5 is on the right side of the
switch.
CAUTION:
DO NOT mix airflow directions. All reverse or normal fans must use the same airflow direction. If you
mix the airflow direction, the switch detects the discrepancy, issues an alarm, and may autoshutdown to avoid
heat damage to the components. If an autoshutdown occurs, correct the mixed airflow direction.
1.
Take the fan module out of the shipping box.
2.
Slide the module into the bay.

Fan module replacement
1.
Slide the fan module out of the bay.
2.
Slide the replacement module into the bay.
Fan air filter replacement
Environmental factors can decrease the amount of time required between air filter replacements. Check the environmental
factors regularly. An increase in temperature and/or particulate matter in the air might affect performance.
CAUTION:
Check the fan air filters at six-month intervals and replace them as necessary. To accurately
determine air filter replacement intervals, regularly monitor the speeds of the cooling fans. An increase in
overall fan speed may indicate a clogged filter.
You must replace the fan air filters with new filters; you cannot clean and reuse the old fan air filters. Replacement filter media
must meet the requirements found in GR-63-CORE.
