The Cisco 10000 ESR is configured to your order and ready for installation when it arrives. After you install the system, you may have to perform specific maintenance procedures to ensure the router is operating properly. These procedures can include routine maintenance such as replacing the filter, upgrading system components, or replacing components with field replaceable units (FRUs). This chapter contains the information necessary to perform that maintenance for the Cisco 10000.
 |
Note Detailed, up-to-date instructions are also shipped with all FRUs and upgrade kits. |
System components fall into two categories: hot swappable components that do not require you to power off the system before replacing them, and those components that do require you to power off the system before you replace them. For example, all line cards are hot-swappable and can be replaced without powering off the system, but you must power off the system before replacing a single power entry module (PEM) or a single Performance Routing Engine (PRE).
|
Note To prevent alarms from activating, you must administratively shut down a line card before hot swapping it. |
Service providers usually draw on their own experience with similar equipment as they try to determine the number of spare parts of a given item to keep on hand. In developing a strategy for spare parts, the service providers must
Service providers may also subscribe to services that supply them with replacement parts, sometimes with turnaround times as short as 4 hours.
Service providers trying to decide on the level of redundancy appropriate for their operations must examine their business models. The service provider invests more heavily in high network reliability if the business model
In addition, the service provider discusses the situation with the supplier to identify those software and hardware features likely to experience the most stress and thus to have the shortest mean time between failures. The point is to determine, not just whether or not redundancy is to be used, but also the quantity to be used (1:1, 2:1, or greater).
Some service providers have redundant chassis, but not redundant routing engines. This approach gives them increased flexibility, so that they can provide reliable service and accommodate a growing number of customers. Customers requiring the highest levels of network reliability and availability often add redundancy by connecting to two different service providers.
The only tools required to perform the maintenance procedures described in this chapter are:
Although most components in the Cisco 10000 are hot-swappable, you may have to shut down the system under certain circumstances. Use the following procedure to shut down the system.
Step 2 Before you shut down the router, use the copy command to save any configuration changes to NVRAM, and also, if you wish, to a PCMCIA Flash card (see the Cisco 10000 ESR Software Configuration Guide for instructions about using the copy command).
Step 3 Power down the system by setting the power switch on all PEMs to the off (0) position (your system can be configured with one or two PEMs).
Cisco recommends that you create a duplicate PCMCIA card that contains the current boot software image and the current software configuration. You can use the backup card to quickly recover from a major system failure. You can also use a backup card to load a new PRE module and avoid the time-consuming reconfiguration process. For instructions to create a backup PCMCIA card, refer to the Cisco 10000 ESR Software Configuration Guide.
This section contains the procedures to remove and replace all of the field replaceable units (FRUs) for the Cisco 10000. Before beginning any FRU procedure, be sure you are familiar with the safety precautions outlined in "Preparing for Installation."
The Cisco 10000 is equipped with a plastic front cover that ensures proper air flow through the system and protects the cables and connectors from damage. The following procedures describe how to remove and replace the front cover.
Use the following procedure to remove the front cover from the chassis:
Repeat this procedure for all four bezel plugs, and then remove the plugs.
Step 2 Remove the cover by lifting it up slightly and then pulling it toward you (Figure 4-2).
Use the following procedure to replace the front cover on the chassis:
Step 2 Insert a bezel plug into each hole below the corner posts and press in the top of each bezel plug to secure the front cover to the chassis (Figure 4-4).
Use the following procedure to replace the air filter:
Step 2 Loosen the captive screws on the air filter tray (Figure 4-5).
Step 3 Pull the filter tray out enough to remove the air filter (Figure 4-6).
Step 4 Hold the new air filter so that you can see the directional arrows located on the metal frame and slide the filter into the chassis (see Figure 4-7).
Step 5 Tighten the captive screws to secure the filter to the chassis (Figure 4-7).
Step 6 Replace the front cover (see the "Replacing the Front Cover" section).
Use the following procedure to replace a blower module. The blower module supports hot-swapping (for up to 2 minutes) and can be replaced without interruption to system operation.
 |
Caution To prevent the possibility of the system overheating, be sure that the replacement blower module is out of its box and packaging, so it is ready to install as soon as the defective module is removed. |
Step 2 Move any interface cables from the cable brackets on the blower so they are out of your work area, and then remove the cable brackets from the blower (Figure 4-8).
Step 3 Loosen the captive screws on each side of the blower module and slide the module out of the chassis (Figure 4-9).
Step 4 Slide the new blower module into the chassis being sure it makes a secure connection to the backplane (Figure 4-10).
The FANS OK LED should light (green).
If a FAN FAILURE LED lights (yellow):
Step 5 Tighten the captive screws on each side of the blower module (see Figure 4-10).
Step 6 Rerun all interface cables through the cable management brackets.
Step 7 Replace the front cover (see the "Replacing the Front Cover" section).
This section contains the procedures to install or replace AC or DC PEMs.
|
Note If you are adding a second PEM for redundancy, or if you have redundant PEMs, it is not necessary to shut down the system before replacing a PEM. |
Use the following procedure to install a second DC PEM in the bottom power bay for redundancy.
|
Caution Do not power off the primary DC PEM or all data traffic will halt. |
Step 2 Loosen the captive screws to remove the blank cover from the bottom power bay (Figure 4-12).
Step 3 Install the new DC PEM all the way into the power bay to ensure a secure connection to the backplane, and tighten the captive screws (Figure 4-13).
Step 4 Loosen the captive screw on the rear safety cover and tilt back the cover (Figure 4-14).
Step 5 Remove the safety cover by lifting it up and out from the chassis (Figure 4-15).
Step 6 Connect the DC PEM power leads:
Step 7 Secure the power cabling to the chassis by feeding a tie wrap through the slot on the side of the chassis and binding the cables (Figure 4-17).
Step 8 Replace the rear safety cover, making sure that the power cables exit through the holes on the side of the cover (Figure 4-17).
Step 9 Set the power switch to the on (|) position (Figure 4-18).
Step 10 Replace the front cover (see the "Replacing the Front Cover" section).
Use the following procedure to replace a DC PEM:
Step 2 Set the power switch to the off (0) position. If you have redundant PEMs, set only the power switch of the PEM you are replacing to the off (0) position (the example in Figure 4-19 shows the top PEM in the off position).
|
Caution Do not power off both of the DC PEMs in a redundant system, or the system shuts and down all data traffic stops. Only power off the DC PEM you are replacing. |
Step 3 Loosen the captive screws on the DC PEM you are removing and pull the PEM from the chassis using the handle on the faceplate (Figure 4-20).
Step 4 Install the new DC PEM all the way into the power bay to ensure a secure connection to the backplane, and tighten the captive screws (Figure 4-21).
Step 5 Set the power switch to the on (|) position (Figure 4-22).
Step 6 Replace the front cover (see the "Replacing the Front Cover" section).
Use the following procedure to install a second AC PEM in the bottom power bay for redundancy:
Step 2 Loosen the captive screws to remove the blank cover from the bottom power bay (Figure 4-23).
Step 3 Install the new AC PEM all the way into the power bay to ensure a secure connection to the backplane and tighten the captive screws (Figure 4-24).
Step 4 Connect the power cord from the PEM to your power cord that connects to the facility VAC input.
Step 5 Set the AC power cord connectors in a canoe to prevent them from accidently disconnecting (Figure 4-25).
Step 6 Plug the facility AC input power cord into a power receptacle.
Step 7 Set the power switch to the on (|) position (Figure 4-26).

Step 8 Replace the front cover (see the "Replacing the Front Cover" section).
Use the following procedure to replace an AC PEM:
Step 2 If your system is configured with redundant PEMs, set only the power switch of the PEM you are replacing to the off (0) position (the example in Figure 4-27 shows the top PEM in the off position).
|
Caution Do not power off both AC PEMs in a redundant system, or the system shuts down and all data traffic stops. Only power off the AC PEM you are replacing. |
Step 3 Remove the PEM power cable from its canoe and disconnect it from the AC input power cable.
Step 4 Loosen the captive screws on the PEM you are removing and pull the PEM from the chassis using the handle on the faceplate (Figure 4-28).
Step 5 Install the new AC PEM all the way into the power bay to ensure a secure connection to the backplane and tighten the captive screws on the PEM (Figure 4-29).
Step 6 Connect the power cord from the PEM to the power cord that connects to the facility VAC input.
Step 7 Set the AC power cord connectors in a cord strain relief (canoe) to prevent them from accidently disconnecting (Figure 4-30).
Step 8 Plug the facility AC input power cord into a power receptacle.
Step 9 Set the power switch to the on (|) position (Figure 4-31).

Step 10 Replace the front cover (see the "Replacing the Front Cover" section).
The Cisco 10000 provides relay contacts for optional (customer-supplied) audible or visual alarm indicators. Relay contacts are provided for three levels of severity:
Use the following procedure to connect an alarm indicator to the system:
Step 2 Loosen the captive screw on the rear safety cover and tilt the cover back (Figure 4-32).
Step 3 Remove the safety cover by lifting it up and out from the chassis (Figure 4-33).
Step 4 Strip not more than 0.4 inches (10 mm) of insulation off of the ends of the alarm indicator wire (Figure 4-34).
Step 5 Connect one set of alarm indicator wires to the alarm terminal block as follows:
a. Connect one lead to the common (COM) terminal (Figure 4-35).
b. Connect the other lead to the normally closed (NC) or normally open (NO) terminal.
Step 6 Repeat steps 1 and 2 for any remaining alarm indicators.
Step 7 Secure the power cabling to the chassis by feeding a tie wrap through the slot on the side of the chassis and binding the cables (see blowout in Figure 4-36).
Step 8 Replace the rear safety cover, making sure that the alarm indicator wires exit through the holes on the side of the cover (Figure 4-36).
Use the following procedure to remove and replace the following line cards from the chassis:
|
Note The illustrations in this procedure use a 6-port T3 line card as an example. |
Step 2 Attach an antistatic wrist strap to your wrist and to the ESD connection socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 4-37).
Step 3 Disconnect any interface cables from the line card if necessary.
Step 4 Unscrew the top and bottom captive screws on the line card (Figure 4-38).
Step 5 Simultaneously pivot both ejector levers away from each other to disengage the line card from the backplane (Figure 4-39).
Step 6 Slide the line card out of the slot and place it on an antistatic surface, or in an antistatic bag (Figure 4-40).
Step 7 Grasp the faceplate of the new line card with one hand and place your other hand under the card carrier (to support the weight of the card) and position the card in front of the card cage slot.
Step 8 Carefully align the upper and lower edges of the line card with the upper and lower guides in the chassis, and slide the line card into the slot until you can feel it begin to seat in the backplane connectors (Figure 4-41).
Step 9 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane (Figure 4-42).
Step 10 Secure the line card in the chassis by tightening the top and bottom captive screws (Figure 4-43).
|
Caution To ensure that there is adequate space for additional line cards, always tighten the captive screws on each newly installed line card before you insert any additional line cards. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding. |
Step 11 Reconnect any interface cables to the line card if necessary.
Step 12 Replace the front cover (see the "Replacing the Front Cover" section).
Step 13 Configure the line card if necessary (see the "Formatting Flash Memory Cards and Disks" section, or the Cisco 10000 ESR Software Configuration Guide, for information about configuring the line card).
|
Note It is not necessary to configure the line card if this is a replacement installation. The system automatically downloads the necessary configuration information from the PRE. |
Use the following procedure to install or to remove and replace a PRE module:
Step 2 Attach an antistatic wrist strap to your wrist and to the ESD socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 4-44).
Step 3 Disconnect any interface cables from the PRE if necessary.
Step 4 Remove the PCMCIA card from the PRE (see the "Removing and Installing a PCMCIA Flash Memory Card" section).
Step 5 Unscrew the top and bottom captive screws on the PRE (Figure 4-45).
Step 6 Simultaneously pivot both ejector levers away from each other to disengage the PRE from the backplane (Figure 4-46).
Step 7 Slide the PRE out of the slot and place it on an antistatic surface, or in an antistatic bag (Figure 4-47).
Step 8 Grasp the faceplate of the new PRE with one hand and place your other hand under the card carrier (to support the weight of the module) and position the card in front of the card cage slot.
Step 9 Carefully align the upper and lower edges of the PRE with the upper and lower guides in the chassis, and slide the module into the slot until you can feel it begin to seat in the backplane connectors (Figure 4-48).
Step 10 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the PRE in the backplane (Figure 4-49).
Step 11 Secure the PRE in the chassis by tightening the top and bottom captive screws (Figure 4-50).
|
Caution Always tighten the captive screws on each newly installed PRE. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding. |
Step 12 Reconnect any interface cables to the PRE if necessary.
Step 13 Install the PCMCIA card in the PRE if necessary (see the "Removing and Installing a PCMCIA Flash Memory Card" section).
Step 14 Refer to the Cisco 10000 ESR Software Configuration Guide, for information about configuring the PRE if necessary.
|
Note It is not necessary to configure the PRE if this is a second PRE installation for redundancy. The system automatically downloads the necessary configuration information from the primary PRE. |
Step 15 Replace the front cover (see the "Replacing the Front Cover" section).
Use the following procedure to remove and install a PCMCIA flash memory card:
|
Note For information about formatting Flash memory cards and disks, see the "Formatting Flash Memory Cards and Disks" section. |
Step 2 Loosen the captive screw on the PCMCIA flash card cover on the PRE (Figure 4-51).
Step 3 Lift the cover and pull the flash card up and out of its slot (Figure 4-52).
Step 4 Insert the new PCMCIA flash card into one of the card slots on the PRE (Figure 4-53).
Step 5 Close the cover and tighten the captive screw (Figure 4-54).
Step 6 Replace the front cover (see the "Replacing the Front Cover" section).
You can increase the amount of SDRAM in your system configuration by replacing the two dual in-line memory modules (DIMMs) with higher capacity SDRAM. The default SDRAM configuration is 128 MB, and can be upgraded to either 256 MB or 512 MB to meet your needs (Table 4-1).
|
Note We recommend that you upgrade the SDRAM in both the primary and the secondary PRE in a redundant chassis configuration. The DIMMs that you remove may be used in other compatible equipment and should be stored in an antistatic bag. |
| SDRAM Upgrade Options | Cisco Part Number |
|---|---|
256 MB SDRAM | ESR-PRE-MEM-256M= |
512 MB SDRAM | ESR-PRE-MEM-512M= |
|
Caution To prevent (electrostatic discharge) ESD damage, always wear an ESD-preventive wrist or ankle strap, and handle DIMMs by the edges only. Avoid touching the memory pins or traces (the metal "fingers" along the connector edge of the DIMM). |
The Cisco 10000 system is hot-swappable which means you can remove and replace a PRE while the system is operating---if your configuration includes a secondary (redundant) PRE installed in the chassis. The hot-swapping feature allows you to remove or replace a PRE while the system maintains all routing information and ensures session preservation. See the "Replacing the Performance Routing Engine Module" section to remove the PRE from the chassis.
To remove and replace DIMMs in the PRE module:
|
Caution To upgrade SDRAM, you must install identical DIMMs in both DIMM sockets. Do not mix different types of DIMMs. |
Place the PRE on an antistatic mat or pad so that the DIMMs are facing up (Figure 4-55).
Step 2 Remove each DIMM from its slot by pushing its ejector tabs out to the side and lifting the DIMM straight up (Figure 4-56).
Step 3 Remove a new DIMM from its antistatic bag (Figure 4-57).
|
Caution To prevent (electrostatic discharge) ESD damage, always wear an ESD-preventive wrist or ankle strap, and handle DIMMs by the edges only. Avoid touching the memory pins or traces (the metal "fingers" along the connector edge of the DIMM). |
Step 4 Install each new DIMM by aligning the keys on the DIMM connector over the DIMM slot, and gently pushing the DIMM into the slot until the ejector tabs snap over each end of the DIMM (Figure 4-58).
|
Caution The DIMMs are keyed and can only be inserted one way. When you insert DIMMs, use firm but not excessive pressure. If you damage a DIMM slot, you must return the PRE to Cisco for repair. |
Step 5 Reinstall the PRE in the chassis after both DIMMs are installed.
If the system fails to boot properly, or if the console terminal displays a checksum error after you install the new DIMMs, check the following:
If the system fails to boot properly after you perform these corrective actions, contact the Cisco Technical Assistance Center (TAC) for additional help. Before you contact TAC, make a note of any error messages, unusual LED states, or any other indications that might help the service representative to identify the problem.
