Maintaining the Cisco 6400
Backing Up the PCMCIA Card
Backing Up the PCMCIA Card
We recommend that you create a duplicate PCMCIA card that contains the current boot software image
and the current software configuration. You can use the duplicate to recover from a major system failure
with less disruption. If you have a backup PCMCIA card, you can use that card to load a new node switch
processor (NSP) module and avoid a time-consuming reconfiguration process. For instructions on
creating a backup PCMCIA card, refer to Cisco 6400 Software Setup Guide.
Maintaining the Air Filter
The Cisco 6400 automatically powers down if the system overheats. If the blower module’s air filters are
too dirty or clogged, the system might have insufficient air flow and might overheat.
You should replace the Cisco 6400 air filters every six months. In certain environments, you might have
to replace the air filter more frequently.
Removing the Air Filter
The Cisco 6400 ships with either a screw-type or tab-type air filter.
To remove a tab-type air filter, press the release tabs on each side of the chassis to release the air filter
and slide it out of the chassis. (See
.)
Figure 5-6
Tab-type Air Filter Release Tabs
To remove a screw-type air filter, refer to
and perform the following steps.
Step 1
Locate the filter tray at the bottom front of the chassis, below the plug-in modules. Use a number 2
Phillips screwdriver to unlock the filter tray.
Step 2
Gently pull the filter toward you to remove it from the chassis.
Step 3
If you are replacing the filter, discard the old filter and go to the section "
