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.
•
Minimum dust arrestance of 65%, per ASHRAE Standard 52.1-1992. OR
•
Minimum Efficiency Rating Value (MERV) of 2, per ANSI/ASHRAE Standard 52.2-2007.
CAUTION:
For Network Equipment Building Systems (NEBS) compliance, use NEBS approved filters.
Use fan air filters with reverse blue-banded air flow switches—PSUs and fans. You can replace the air filters individually on each fan within
the switch without powering down a PSU module or disrupting traffic.
The fan air filter media slides into the frame from the top. No tools are required.
1
