Fan module installation
The fan modules in the S6000–ON are eld 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 airow directions. Both fans must use the same airow direction—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.
Fan module replacement
CAUTION: Complete steps 1 and 2 within one minute or the system powers down.
1  Use the grab handle to slide the fan module out of the bay.
2  Use the grab handle on the replacement module to slide it into the bay.
Fan air lter replacement
Environmental factors can decrease the amount of time required between air lter replacements. Check the environmental factors regularly. 
An increase in temperature and/or particulate matter in the air might aect performance.
CAUTION
: Check the fan air lters at six-month intervals and replace them as necessary. To accurately determine air lter 
replacement intervals, regularly monitor the speeds of the cooling fans. An increase in overall fan speed may indicate a clogged 
lter.
You must replace the fan air lters with new lters; you cannot clean and reuse the old fan air lters. Replacement lter media must meet 
the requirements found in GR-63-CORE.
• Minimum dust arrestance of 65%, per ASHRAE Standard 52.1-1992. OR
• Minimum Eciency Rating Value (MERV) of 2, per ANSI/ASHRAE Standard 52.2-2007.
CAUTION
: For Network Equipment Building Systems (NEBS) compliance, use NEBS approved 
lters.
Use fan air lters with reverse air ow systems (blue banded PSUs and fans). You can replace the air lters individually on each fan within 
the system without powering down a PSU module or disrupting trac.
The fan air lter media slides into the frame from the top. No tools are required.
1  Determine which lters to replace.
2  Unlatch and remove the rst module that needs the lter replaced.
3  Slide the existing lter upwards to remove it from the module.
4  Replace the lter with a new lter of the same size.
5  Repeat for the remaining modules that need the lter replaced.
