Upgrading and Maintaining the Cisco 6160 System
This chapter describes upgrade and maintenance procedures for the Cisco 6160 system. The chapter includes the following sections:
•
Backing Up Software
• Removing and Installing Hardware
• Air Filter Maintenance
6.1 Backing Up Software
We recommend that you maintain, on a TFTP server, current copies of three files for each Cisco 6160 system.
•The Cisco IOS software image
•The bootflash file
•The configuration file (running-config)
If you keep copies of these files on a TFTP server, you can easily recover from a fault in an NI-2 card. You can simply replace the NI-2 card, then download the software image, bootflash and configuration file from the TFTP server. Remember to update your backup files whenever you change your configuration or upgrade your Cisco IOS software.
Note For more information about copying Cisco IOS software images and examples of the procedure, refer to the Configuration Guide for Cisco DSLAMs with NI-2.
To copy the Cisco IOS software image, the bootflash, and configuration file to a TFTP server, complete the following steps in privileged EXEC mode:
Step 1 Enter the dir command to display the names of the files:
6160# dir
Step 2 Enter a copy command to copy the IOS software file to the node TFTP server:
6160# copy flash:<image-name> tftp
Step 3 Enter a copy command to copy the bootflash file to the node TFTP server:
6160# copy bootflash:<image-name> tftp
Step 4 Enter a second copy command to copy the configuration file to the node TFTP server:
6160# copy running-config tftp

Caution Proper ESD protection is required whenever you handle Cisco equipment. Installation and maintenance personnel should be properly grounded by means of grounding straps to eliminate the risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever it is removed from the chassis.
6.2.1 xTU-C Line Card
The following sections describe how to remove and install an xTU-C line card in the Cisco 6160 chassis.
6.2.1.1 Removing an xTU-C Line Card
Complete the following steps to remove an xTU-C line card from the chassis:
Caution When a line card is removed from the chassis, service is interrupted for the subscribers served by that line card.
Step 1 Connect a grounding strap to the ESD grounding jack on the chassis. See the "Preventing Electrostatic Discharge Damage" section for the ESD grounding jack location on the Cisco 6160.
Step 2 Use a flat-head screwdriver to move the locking tab from the locked to the unlocked position. Be sure to turn the locking tab so that it does not overlap the ejector lever as shown in Figure 6-1.
Figure 6-1 Positioning the Locking Tab for Line Card Removal and Installation
Step 3 Lift the ejector lever to disconnect the line card from the backplane.
Step 4 Carefully slide the line card out of the slot.
Either replace the line card that you remove, or insert a blank faceplate in the empty slot. For line card installation instructions, see the "Installing an xTU-C Line Card" section. For blank faceplate installation instructions, see the "Installing a Blank Faceplate" section.
Note Blank faceplates should occupy any empty line card slots in the chassis.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
6.2.1.2 Installing an xTU-C Line Card
Complete the following steps to install an xTU-C line card in the chassis:
Note All cards must be fully seated in the chassis. Push on the faceplate of each card to be sure that the card is fully seated.
Step 1 Connect a grounding strap to the ESD grounding jack on the chassis. See the "Preventing Electrostatic Discharge Damage" section for the ESD grounding jack location on the Cisco 6160.

6.3 Air Filter Maintenance
You must periodically clean or replace the air filter in the Cisco 6160 chassis.
Once a month (or more often in dusty environments), examine the air filter and clean or replace it if it is dirty. Keep a log recording the date that the filter was cleaned or replaced.
Note You can clean or replace the air filter while the Cisco 6160 remains powered up and fully operational.
The remainder of this section explains how to remove, clean, and replace the filter.
6.3.1 Required Tools and Equipment
To clean the air filter, you need one of the following:
•Vacuum cleaner (preferred)
•Clean water
•Mild detergent, if the filter is very dirty
•Phillips-head screwdriver
A new air filter (product number 6160-AF-01= for a 5-pack) is the only part you need if you decide that the old filter needs replacing.
6.3.2 Removing an Air Filter
Complete the following steps to remove an air filter from the Cisco 6160 chassis:
Step 1 Use a Phillips-head screwdriver to unscrew the two captive screws located on the perforated metal bezel that covers the air filter. (See Figure 6-15.)
Step 2 Remove the metal bezel.
Step 3 Remove the filter from the chassis.

6.3.3 Cleaning or Replacing the Air Filter
This section describes how to clean or replace a Cisco 6160 air filter.
Step 1 Use one of the following methods to clean the air filter:
•Vacuum the filter until it is clean and free of dust. This method is preferred because you need not dry the filter afterwards.
•Wash the filter by holding it under a stream of plain water. Supporting the filter with your fingers, hold the filter under the water with the metal grill facing up and let the water flow down through the filter. (This orientation causes the water to flow through the filter in the direction opposite from the usual air flow, so you dislodge rather than embed matter trapped in the filter.) Allow the filter to dry thoroughly before reinstalling it.
•If the filter is extremely dirty, immerse the filter in a solution of hot water and mild detergent. Rinse the filter thoroughly in clear water and allow it to dry completely before reinstalling it.
Step 2 To replace the clean filter or to install a new one, hold the filter so that the side with the metal grill is facing the chassis.
Step 3 Insert the filter into its slot at the bottom of the chassis.
Step 4 Replace the bezel that covers the air filter and use a screwdriver to tighten the captive screws to secure the bezel.
