Maintaining the
Cooling
Components
The Net-Net 6300 Air Filter removes airborne particles before they are drawn into
the Net-Net 6300. To prevent system malfunction and prolong the life of the
system’s cooling components:
• Clean or replace the Fan Filter every three months
•
Clean the air inlets once a week.
Cooling maintenance encompasses cleaning the fan module and cleaning the air
inlets on the front of the Net-Net 6300. Cleaning the fan module requires that you
remove the module itself. If you are not shutting down the Net-Net 6300 this
procedure must be performed quickly or else the system may overheat and cause
packet processing to stop.
This maintenance should be performed alongside of other preventative maintenance
to take place within a planned maintenance or downtime window, during off-peak
hours.
Cleaning the Cooling
Components To clean the Fan module:
1. Refer to the instructions detailed in this chapter’s Fan and Filter Maintenance
section to remove the Fan from the chassis.
2. Spray compressed air into the Fan to dislodge and blow away any contaminants
and clean out the 15 fans.
3. Refer to the instruction detailed in this chapter’s Fan and Filter Maintenance
section to replace the fan module.
To clean the perforated air inlets:
1. Remove the Fan Bezel from the chassis.
2. Gently wipe the front Fan Bezel that contains the perforated air inlets with a
clean, dry cloth. You can alternatively remove the Fan Bezel from the system and
use compressed air to clean out the perforated air inlets.
Note: Only the removable fan bezel has vent holes that require
cleaning.
Caution To prevent damage to the painted finish, do not use any
solvents or liquids to clean the perforated air inlets on the
front of the chassis.
NIU Removal and Replacement
When possible, remove system power before removing and replacing an NIU.
However, without powering down the Net-Net 6300 you can exchange an NIU (for
the same type of card) by removing and replacing it. Upon NIU removal, the Net-
Net 6300 enters an Out-of-Service state. After you reinsert the NIU and connect to
the ACLI, you must reboot the system to return to service. This causes a soft-reboot
rather than a system power cycle.
