This chapter describes upgrade and maintenance procedures for the Cisco 6100 with NI-2 system.
We recommend that you maintain, on a TFTP server, current copies of two files for each Cisco 6100 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 image 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 IOS software file to the node TFTP server:
Step 4 Enter a second copy command to copy the configuration file to the node TFTP server:
The following sections describe the preventive maintenance procedures for the fan tray:
The air filter is located directly below the three fan modules in the fan tray. When this filter becomes dirty, replace it. 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, use these steps:
Step 2 Locate and unscrew the three thumbscrews shown in Figure 5-1.
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 5-2). 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. (See Figure 5-3.)
Step 6 Slide the filter into its slot at the bottom of the fan tray. (See Figure 5-3.)
Step 7 Place the air filter door back on the fan tray and tighten the three thumbscrews. (See Figure 5-3.)
Step 8 Discard the used air filter.
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, use these 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 5-4.)
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 5-5.)
 |
Caution It is important that the Cisco 6100/6130 cooling fans run continuously. The system could suffer thermal damage if the fans stop running for more than 30 minutes. |
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.
The following sections detail the installation and removal procedures for the following field replaceable unit (FRU) hardware components:
 |
Note See the "Installation and Replacement Suggestions" section for examples of recommended card installation and replacement practices. |
|
Caution Proper ESD protection is required whenever you handle Cisco digital subscriber line access multiplexer (DSLAM) equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage whenever they are removed from the chassis. |
The following sections describe how to remove and replace or install a 4xflexi.

Step 7 Press down on the ejector tab to secure the line card and connect it to the backplane.
Step 8 Use a flat-head screwdriver to turn the locking tab so that it overlaps the 4xflexi to prevent inadvertent dislodging. Figure 5-7 shows how to position the locking tab.
Step 9 Verify that the STATUS LED is solid green after the brief self-test. If the STATUS LED is not green after the self-test, see "Troubleshooting" for troubleshooting procedures.
|
Note If you are installing the line card for the first time, refer to the provisioning procedures in the appropriate software guide for your chassis. |
Complete the following steps to remove a 4xflexi from the chassis:
Step 2 Open the front cover on the chassis, as necessary.
Step 3 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 4xflexi as shown in Figure 5-7.
Step 4 Lift up on the ejector tab. This action disconnects the line card from the backplane.
Step 5 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. See the "Installing a 4xflexi" section for 4xflexi installation instructions. For blank faceplate installation instructions, see the "Install Blank Faceplates" section.
The following sections describe how to remove and replace or install a DS3/2DS3 NI-2 card.
|
Warning The ports labeled "ENET," "CNSL," and "AUX" are SELV circuits. SELV circuits should be connected only to other SELV circuits. Because the DSL circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the TNV circuits. |
 |
TimeSaver Cisco recommends that you label each data cable at both ends to identify its destination. |
|
Caution Service is interrupted for the entire system when the NI-2 card is removed. |
|
Caution Proper ESD protection is required each time you handle Cisco DSLAM equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage each time they are removed from the chassis. |
|
Caution Installing the cards in the chassis with the power leads reversed can damage the cards. |
|
Warning The power supply circuitry for the Cisco DSLAM equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches).
