Upgrading and Maintaining the Cisco 6130 System

This chapter describes upgrade and maintenance procedures for the Cisco 6130 with NI-2 system, which includes

Backing Up Software

Cisco recommends that you maintain, on a TFTP server, current copies of three files for each Cisco 6130 with NI-2 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 images and configuration file to a TFTP server:

Step 2   Enter the dir command to display the names of the files:

Step 3   Enter a copy command to copy the Cisco IOS software file to the node TFTP server:

Step 4   Enter a second copy command to copy the Cisco IOS boot image file to the node TFTP server:

Step 5   Enter a third copy command to copy the configuration file to the node TFTP server:

Fan Tray Maintenance

The following sections describe the preventive maintenance procedures for the fan tray:

Replacing the Air Filter in the Fan Tray

The air filter is located directly below the three fan modules in the fan tray. Replace the air filter every 60 days. If you notice a significant accumulation of dust in the filter prior to 60 days, replace the filter at that time. Record the date each time you replace the filter.

You can order a replacement air filter (part number 6100-AF-01=) through Cisco.

To replace the air filter, complete the following steps:

Step 2   Locate and unscrew the three thumbscrews shown in Figure 6-1.

Step 3   Carefully remove the air filter door.

Step 4   Slide the air filter out from the bottom of the fan tray. Gently pull the used air filter toward you to remove it from the fan tray (see Figure 6-2). The fan tray remains operational while you replace the air filter.

Step 5   Hold the replacement air filter so that the air flow arrows on the end of the air filter face upward, as shown in Figure 6-3.

Step 6   Slide the filter into its slot at the bottom of the fan tray. (See Figure 6-3.)

Step 7   Place the air filter door back on the fan tray and tighten the three thumbscrews. (See Figure 6-3.)

Step 8   Discard the used air filter.

Replacing Fans in the Fan Tray

If a fan module is running too slowly or is no longer operational, an alarm is generated in the system management software. You will need to replace the nonoperational fan module. While you are replacing the nonoperational fan module, the operational fan modules continue to run. You can order a replacement fan module (part number 6100-FU-01=) through Cisco.

Warning If you do not have a replacement fan available, pull all of the line cards away from the backplane connection and power off the system until a replacement fan module is available.

To replace a fan module in the fan tray, complete the following steps:

Step 2   Locate the fan module and unscrew the thumbscrew (the screw at the top of the fan module) that holds the fan module in place. (See Figure 6-4.)

Step 3   Carefully remove the fan module by pulling it toward you. The fan module is located on slide rails for easy removal and installation. (See Figure 6-5.)

Caution   It is important that the chassis cooling fans run continuously while the system is powered.

Step 4   Align the new fan module with the fan tray slide rails inside the fan tray.

Step 5   Slide the replacement fan module into the fan tray.

Step 6   Tighten the thumbscrew above the replacement fan module.

Step 7   Discard the used fan module.
