This chapter describes upgrade and maintenance procedures for the Cisco 6260 system.
We recommend that you maintain, on a TFTP server, current copies of three files for each Cisco 6260 system:
If you keep copies of these files on a TFTP server, you can easily recover from a fault in an NI-2 card: simply replace the NI-2 card, and download the software image and configuration file from the TFTP server. Remember to update your backup files whenever you change your configuration or upgrade your Cisco IOS software.
Complete the following steps to copy the Cisco IOS software image and configuration file to a TFTP server:
Step 1 Log in to the Cisco 6260 node whose software you wish to back up.
Step 2 Enter the dir command to display the names of the files:
6260# dir
Step 3 Enter a copy command to copy the IOS software file to the node TFTP server:
6260# copy bootflash:<image-name> tftp
Step 4 Enter a second copy command to copy the configuration file to the node TFTP server:
6260# copy running-config tftp
The following sections describe the preventive maintenance procedures for the fan tray:
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.
To clean the air filters, you need one of the following:
New air filters are the only parts you need if you decide that the old filters need replacing.
This procedure tells you how to remove an air filter from the Cisco 6260 chassis. Perform this procedure for each of the two air filters in each chassis.
Step 1 Connect a grounding strap to the ESD grounding jack that is located on the top right of the Cisco 6260 card cage.
Step 2 Using a Phillips-head screwdriver, loosen the screw and remove the metal bezel that covers the air filters. (See Figure 6-1.)
Step 3 The air filter slides out from the top of the fan tray. Gently pull the filter toward you to remove it from the tray.
Step 4 If you are replacing the air filter, discard it and go to the "Replacing the Air Filter" section.
Step 5 If you wish to clean the air filter, go to the "Cleaning the Air Filter" section.
This section tells you how to clean a Cisco 6260 air filter. Go to the "Replacing the Air Filter" section if you are replacing an old filter with a new one.
Use one of the following methods to clean the air filter:
Use these steps to replace the air filter:
Step 1 Hold the air filter so that
Step 2 Slide the filter into its slot above the fan tray.
Step 3 Replace the bezel that covers the fan tray and tighten the screw using a Phillips-head screwdriver to secure the bezel.
If the fans are running too slowly or are no longer operational, the system management software generates an alarm. You will need to replace the nonoperational fan tray. While you are replacing the nonoperational fan tray, the operational fan tray continues to run. You can order a replacement fan tray through Cisco.
The compartments for the two fan trays are located side by side near the bottom of the chassis, just above the PEMs. A narrow bezel fits across the chassis to hold the air filters and fan trays in place (see Figure 6-2).
You need a Number 2 Phillips-head screwdriver to remove and replace the bezel and to tighten the screws that secure the fan tray to the chassis.
 |
Note You need not turn off the power before removing a fan tray. However, if you must remove a fan tray from an operating Cisco 6260, replace it within 5 minutes. If that is not possible, shut the system down and turn off the power to avoid thermal damage. |
 |
Warning If you do not have a replacement fan tray available, pull all of the line cards away from the backplane connection and power off the system until a replacement fan tray is available. |
 |
Caution The cooling fans in both fan trays must run while the system is powered up. The system could suffer thermal damage if the fans in either tray stop for more than 5 minutes. |
Complete these steps to remove and replace a fan tray in the Cisco 6260:
Step 1 Connect a grounding strap to the ESD grounding jack located on the top right of the Cisco 6260 card cage.
Step 2 Use a Phillips-head screwdriver to loosen the screw to remove the bezel that partially covers the fan trays.
Step 3 Use a Phillips-head screwdriver to loosen the two screws on the fan tray.
Step 4 Grasp the fan tray by the handle and pull it from the chassis. If the fans are running, you will hear them slow down as the tray disengages from its power connector.
|
Warning The fans continue to turn at high speed for several seconds after the fan tray is removed from the chassis. To avoid injury to your hands, touch the fan tray only by its handle until the fans have stopped. |
|
Note If there is a second fan tray in the chassis, you will hear it speed up when you remove the first fan tray. |
Step 5 Insert the replacement fan tray into the chassis. Make sure that the pins in the lower lip of the fan tray front panel engage with the holes in the PEM below.
Step 6 Press the fan tray firmly into its slot to ensure that the power connectors mate. If the power is on, you will hear the fans start to turn. The fault light for the fan tray you are installing will stay on until the fans reach full speed, which takes several seconds. (Fan fault LEDs are Fan Tray 1 and Fan Tray 2 on the PEM.)
|
Note When you insert a fan tray, you might hear the fans in the other fan tray slow down; this is normal. |
Step 7 Use the Phillips-head screwdriver to tighten the two fasteners on the fan tray.
Step 8 Use the Phillips-head screwdriver to replace the bezel.
The following sections detail the installation and removal procedures for the following field replaceable unit (FRU) hardware components:
|

Step 3 Remove the fuses from the fuse and alarm panel.
Step 4 Disconnect the wires coming from the fuse and alarm panel to the PEM.
Step 5 Disconnect the grounding wire from the PEM.
Step 6 If a fan tray is present directly above the PEM you wish to remove, use the following steps to remove the fan tray first:
a. Use a Phillips-head screwdriver to remove the bezel that partially covers the fan trays.
b. Use a Phillips-head screwdriver to loosen the screws that hold the fan tray in place.
c. Grasp the fan tray by the handle and pull it away from the chassis. If the fans are running, you will hear them slow down as the tray disengages from its power connector. Wait for the fans to stop before completely removing the tray.
Step 7 Use a Phillips-head screwdriver to unscrew the two screws and prepare to disconnect the PEM from the Cisco 6260 chassis.
Step 8 Hold the extraction handle on the front of the module and carefully slide the module out of the slot.
