Fan module installation
The fan modules in the S6010–ON are field replaceable.
Module slot 0 is on the left side of the chassis; module slot 1 is on the right side of the chassis.
CAUTION:
DO NOT mix airflow directions. Both fans must use the same airflow direction—either reverse or normal.
1
Take the fan module out of the shipping box.
2
Use the grab handle to slide the module into the bay until the latch securely snaps into place.
Fan module replacement
CAUTION:
Complete steps 2 and 3 within one minute or the system powers down.
1
Loosen the securing screws on the sides of the fan module.
2
Use the grab handle to slide the fan module out of the bay.
3
Use the grab handle to slide the module into the bay until the latch securely snaps into place.
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 air flow systems—blue banded PSUs and fans. You can replace the air filters individually on each fan within
the system without powering down a PSU module or disrupting traffic.
