Fan module installation
The fan modules in the Z9100–ON are eld replaceable. Module slot 1 is on the left side of the chassis; module slot 5 is on the right side of
the chassis.
CAUTION: DO NOT mix airow directions. All reverse or normal fans must use the same airow direction. If you mix the airow
direction, the switch detects the discrepancy, issues an alarm, and may auto-shutdown to avoid heat damage to the components.
If an auto-shutdown occurs, correct the mixed airow direction.

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 aect 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 Eciency 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 blue-banded air ow systems—PSUs and fans. You can replace the air lters individually on each fan within
the system without powering down a PSU module or disrupting trac.
