Chapter 6 Upgrading and Maintaining the Cisco 6260 System
Fan Tray Maintenance
6.2 Fan Tray Maintenance
The following sections describe the preventive maintenance procedures for the fan tray:
• Replacing or Cleaning the Air Filter
• Removing and Replacing the Fan Tray
6.2.1 Replacing or Cleaning the Air Filter
You must periodically clean or replace the two air filters in the Cisco 6260.
Once a month (or more often in dusty environments), examine the air filters and clean or replace them
if they are dirty. Keep a log recording the date of each filter cleaning and filter replacement.
You can clean or replace the air filters while the Cisco 6260 remains powered up and fully operational. You
can order a replacement air filter through Cisco.
The remainder of this section explains how to remove, clean, and replace the filters.
6.2.1.1 Required Tools and Equipment
To clean the air filters, you need one of the following:
• Vacuum cleaner (preferred)
• Clean water
• Mild detergent, if the filter is very dirty
New air filters are the only parts you need if you decide that the old filters need replacing.
