Replacing Cisco ASR 9000 Series Router Components

The router is equipped as ordered and is ready for installation and startup when it is shipped. As network requirements change, you may need to upgrade the system by adding or changing components. This chapter describes how to maintain router components.

Prerequisites and Preparation

Before you perform any of the procedures in this chapter, be sure that you:

Have access to the safety and compliance document during the installation, see:

Regulatory Compliance and Safety Information for the Cisco ASR 9000 Aggregation Services Router

Field Replaceable Units

In the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router the following components are field replaceable units (FRU):

  • All line cards
  • RSP cards
  • Power modules
  • Power trays (version 2 power trays only). Note that the router must be powered down before power tray removal.
  • Fan trays
  • Air filters
  • Line card and RSP blank fillers
  • Compact flash disk
  • Gigabit Ethernet small form-factor pluggable (SFP) transceiver modules
  • 10-Gigabit Ethernet small form-factor pluggable (SFP+) transceiver modules
  • 10-Gigabit Ethernet small form-factor pluggable (XFP) transceiver modules
  • Optional card cage doors (Cisco ASR 9010 Router only)

Note The backplane and version 1 power trays are not field-replaceable.


In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the following components are FRUs:

  • All line cards
  • RP cards
  • FC cards
  • Power modules
  • Power trays

The Cisco ASR 9904 Router, Cisco ASR 9922 Router and Cisco ASR 9912 Router use only version 2 power trays.

The Cisco ASR 9000 Series Routers must be powered down before power tray removal.

  • Fan trays and covers
  • Air filters and foam media
  • Blank line card fillers
  • Gigabit Ethernet small form-factor pluggable (SFP) transceiver modules
  • 10-Gigabit Ethernet small form-factor pluggable (SFP+) transceiver modules
  • 100-Gigabit Ethernet small form-factor pluggable (CFP) transceiver modules
  • Optional card cage doors

Note The backplanes and BPID cards are not FRUs but are field serviceable.


Online Insertion and Removal

Most Cisco ASR 9000 Series Routers FRUs can be removed and replaced with the power on and the system operating. This is known as online insertion and removal (OIR). Power modules, fan trays, Route Switch Processor (RSP) cards, Route Processor (RP) cards, Fabric Controller (FC) cards, line cards, shared port adapter (SPA), and SPA interface processor (SIP) cards all support OIR. Unless otherwise noted, the maintenance tasks described in this chapter can be performed while the router remains powered on.


Caution Never unplug all the fan trays at the same time.


Note Although the power trays are not a true FRU because they do not support OIR, a procedure for replacing the power trays in Cisco ASR 9000 Series Routers is included in this chapter if a replacement becomes necessary.


OIR Monitoring

The BPID board monitors OIR by counting the number of card insertions for each slot and saving that information in non-volatile memory. OIR monitoring is done for all fan trays, RSP, RP, FC, and line cards. A card insertion is determined by the CAN Bus Controller (CBC) of the inserted card booting up and sending a CBC message which is intercepted by the BPID board. Note that a CBC reset or power cycle on a card will also be interpreted as a card insertion.


Note A card with an OIR count that exceeds 175 will generate a minor alarm against that slot. If the card OIR count exceeds 200, a major alarm is generated against that slot. Fan tray insertion counts are not checked against a threshold. See the Release Notes for Cisco ASR 9000 Series Aggregation Services Routers for Cisco IOS XR Software Release 3.9.1 for information about CLI commands for obtaining and resetting card insertion data.


Powering Off the Router


Caution Do not turn off the switch on the power tray to remove individual power modules. Power modules support OIR, so they can be removed and replaced with the power on and the system operating.

If it becomes necessary to turn all power off to the router, follow these steps:


Step 1 Set the power switch on each power tray to the off (0) position.

Step 2 Power off all circuit breakers for the source power lines connected to the power trays.

Step 3 Verify that the Pwr OK indicator on each power module is off.

Step 4 Verify that the OK indicator on the fan tray is off.


 

Replacing the Chassis Air Filter

The Cisco ASR 9000 Series Routers are equipped with user-replaceable air filters that help prevent dust from being drawn into the router. One time per month (or more often in dusty environments), examine the air filters for damage and cleanliness.


Note In the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9904 Router, the chassis air filter is not serviceable. We recommend that you replace the filter at regular maintenance intervals. The interval may vary between 3 and 12 months depending on the environment.



Note In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the three air filters (left, center, and right) contain foam media which filters the air going into the chassis. The three air filters can be removed from the chassis so that the foam media (Cisco PIDs 9922-CEN-FLTRMED= and 9922-LR-FLTRMED=) can be replaced on a regular maintenance interval. The interval may vary between 3 and 12 months depending on the environment.



Caution Damage to the air filter can restrict the airflow, cause overheating in the router, and degrade electromagnetic interference (EMI) compliance. Be careful when cleaning and replacing the filter.

Table 5-1 describes the air filter locations for the Cisco ASR 9000 Series Routers.

Removing and Replacing the Fan Trays

Prerequisites

For the Cisco ASR 9010 Router, remove the accessory grill before removing and replacing the fan trays. For the Cisco ASR 9922 Router and Cisco ASR 9912 Router, remove the fan tray cover before removing the fan trays for replacement.

Required Tools and Equipment

  • 6-inch long number 2 Phillips screwdriver (torque 10 in-lb)

Steps

Follow these steps to remove and replace the fan trays:


Caution Never unplug all the fan trays at the same time.


Warning Be sure that the fans have stopped running before removing the fan tray. The fans can take from 3 to 5 seconds to completely stop running after disengaging the fan tray latch. Handling the fan tray before the fans have stopped running could cause fingertip injury.



Note Due to air leakage, the chassis should not be operated with any of the fan trays completely missing. Replace any missing fan tray within five minutes. Any fan tray replacement should be performed when the chassis is back to room temperature.



Note If the accessory grill has been installed on the front of the Cisco ASR 9010 Router, you must remove it before you can remove the lower fan tray. You can remove the accessory grill by simply pulling on the grill until it comes loose. See the “Installing Base Chassis Accessories on the Cisco ASR 9010 Router” section, and Figure 2-52 for information about the accessory grill.



Note If the fan tray cover has been installed on the front of the Cisco ASR 9922 Router or Cisco ASR 9912 Router, you must remove it before you can remove the fan tray. Remove the fan tray cover by simply pulling on the cover until it comes loose.


To remove a fan tray from the chassis (see Figure 2-14, Figure 2-15, Figure 2-16, or Figure 2-17):


Step 1 Use the 6-inch long number 2 Phillips screwdriver to a torque of 10 +/–1 in-lb to loosen the captive screw(s) that secure the fan tray.

Step 2 Use the handle on the fan tray front panel to pull the fan tray halfway out of the module bay.

Step 3 Slide out the fan tray completely from the chassis while supporting it with your other hand.


Warning Use two hands when handling the fan tray. Each Cisco ASR 9010 Router version 1 fan tray weighs about 16 pounds (7.27 kg). Each Cisco ASR 9922 Router fan tray or Cisco ASR 9010 Router version 2 fan tray weighs about 18 pounds (8.18 kg).



 

To install a fan tray into the chassis:


Step 1 Lift the fan tray (with two hands) and slide it halfway into the module bay.

Step 2 Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the module bay.


Caution To prevent damage to the connectors, do not use excessive force when inserting the fan tray into the chassis.

Step 3 Tighten the captive screw(s) on the fan tray using the 6-inch long number 2 Phillips screwdriver to a torque of 10 +/–1 in-lb to secure it to the chassis.

Step 4 Verify that the (green) OK status indicator on the front of the fan tray goes on. If the OK indicator does not light, see the “Troubleshooting the Cooling Subsystem” section.


 

Removing and Replacing Power System Components

The Cisco ASR 9000 Series Routers support OIR of power modules. If you are replacing a redundant power module, you can remove and install the power module while the system remains powered on without causing an electrical hazard or damage to the system. This feature enables you to replace a power module while the system maintains all routing information and ensures session preservation.

However, to maintain operational redundancy and proper cooling, and to meet EMI compliance standards, you must have at least one working power module installed (more than one for a fully configured system). When you remove a failed power module with the router in operation, perform the replacement as quickly as possible. Make sure you have the replacement power module ready before beginning the removal and installation procedure.


Note For the RSP/RP to communicate properly to a power module in a power tray, input power to at least one of the three power modules in the power tray should be present.


This section contains procedures on how to remove and install AC and DC power modules used in the Cisco ASR 9000 Series Routers.


Caution Do not turn off the switch on the power tray to remove individual power modules. Power modules support OIR, so they can be removed and replaced with the power on and the system operating.

Changing Between Version 1, Version 2, AC, and DC Power Modules

Follow these steps when changing between version 1, version 2, AC, and DC power modules:


Step 1 Before making any physical changes, check the software configuration to ensure no ROMMON variable CHASSIS_TYPE (such as CHASSIS_TYPE=10_SLOT) is set to override the chassis type.

Step 5 Install and tighten two screws through the power tray mounting ears on each side into the screw holes in the chassis mounting ears to secure the tray to the chassis.


 

Removing and Replacing Cards from the Chassis

This section describes the procedures for removing and installing an RSP, RP, FC, or line card.

See the Cisco ASR 9000 Series Aggregation Services Router SIP and SPA Hardware Installation Guide for information about removing and installing SIP and SPA cards.


Caution Handle all cards by the metal card carrier edges only; avoid touching the board or any connector pins. After removing a card, carefully place it in an antistatic bag or similar environment to protect it from ESD and dust in the optic ports (fiber-optic line cards).


Caution Be careful to avoid damaging the EMI gasket that runs along the full height of the card front panel edges. Damage to the EMI gasket can affect the ability of your system to meet EMI requirements.


Caution To avoid damaging card mechanical components, never carry an RSP, RP, FC, or line card by the captive installation screws or ejector levers. Doing so can damage these components and cause card insertion problems.


Note The BPID board monitors OIR by counting the number of card insertions for each slot and saving that information in non-volatile memory. OIR monitoring is done for all line cards, the RSP, the RP, and the fan trays. See the “OIR Monitoring” section for more information.


Removing Cards from the Chassis

Follow these steps to remove and replace an RSP, RP, FC, or line card from the card cage:


Step 1 Disconnect any cables from the card.

a. Identify the type of line card and its slot number. Write this information down before you disconnect the cables. You’ll need this information when you reinstall the line cards.

b. Identify the line card cable and its port connection. Label the cable with this information.

c. Starting with the port of the line card farthest from the cable management bracket, disconnect the interface cable connectors from each of the line card ports.

d. Carefully remove the cables from the cable-management bracket attached to the front panel of the line card.

e. (Optional) Use the 6-inch long number 2 Phillips screwdriver to a torque of 10 +/–1 in-lb to loosen the captive screw that secures the cable-management bracket to the line card and remove the cable-management bracket from the line card.

f. Carefully remove the cables from the horizontal cable management tray at the top of the chassis or side cable management brackets (Cisco ASR 9006 Router) and carefully place the cable bundle out of the way.

Step 2 Remove the card (see Figure 2-24, Figure 2-25, Figure 2-31, or Figure 2-32):

a. Use the 6-inch long number 2 Phillips screwdriver to loosen the captive screws at each end of the card front panel.

b. On the FC card (see Figure 2-29), push in both ejector lever release buttons.

c. Pivot the ejector levers to unseat the card from the backplane connector.

d. Slide the card out of the slot and place it directly into an antistatic bag or other ESD-preventive container.

Step 3 Repeat Step 1 and Step 2 for each card.


 

Replacing Cards in the Chassis

Follow these steps to replace a previously removed RSP, RP, FC, or line card from the card cage:


Step 1 Install the card (see Figure 2-24, Figure 2-25, Figure 2-31, or Figure 2-32):

a. Slide the card into the slot, being sure to install the card in the same slot you recorded when you removed the card.

b. Use the 6-inch long number 2 Phillips screwdriver to a torque of 10 +/–1 in-lb to tighten the captive screws at each end of the card front panel.

c. Pivot the ejector levers to seat the card into the backplane connector.

Step 2 Reconnect cables to the card:

a. If you previously disconnected the card cable management bracket, reattach it to the card and use the 6-inch long number 2 Phillips screwdriver to a torque of 10 +/–1 in-lb to tighten the captive screw on the bracket to secure it to the card front panel.

b. Carefully reroute the cables through the horizontal cable management tray at the top of the chassis (the Cisco ASR 9922 Router has an additional tray at the bottom of the chassis) or side cable management brackets (Cisco ASR 9006 Router and Cisco ASR 9904 Router).

c. Carefully reroute cables through the card cable-management bracket.

d. Starting with the port of the card closest to the cable management bracket, reconnect the interface cable connectors to each of the card ports using the cable and port connection information you recorded when removing the cables.

Step 3 Repeat Step 1 and Step 2 for each card.


 

Removing a Chassis from the Equipment Rack

Follow these steps to remove the chassis and its components from the equipment rack:


Warning You must use two people to remove the chassis from the equipment rack safely. An empty chassis can weigh up to approximately 300 pounds (136 kg).



Step 1 Power off the router (see the “Powering Off the Router” section).

Step 2 Power off the circuit breakers to the power supplies.

Step 3 Disconnect the power from the power modules on the rear of the chassis:

Step 4 Disconnect the supplemental bonding and grounding connection from the chassis (see the Supplemental Bonding and Grounding Connections, page 53 ).

Step 5 Remove the fan tray (see the “Removing and Replacing the Fan Trays” section).

Step 6 Disconnect RSP/RP cables connected to the console port, auxiliary port, or either of the management Ethernet ports. Be sure to label each of the RSP/RP cables before you disconnect the cables.

Step 7 Disconnect any cables connected to the external alarm port on the alarm display.

Label each of the alarm display cables before you disconnect the cables.

Step 8 Disconnect the line card interface cables.

Step 9 Remove RSP, RP, FC, and line cards from the chassis (see the “Removing and Replacing Cards from the Chassis” section).

Step 10 Remove the chassis air filter (see the “Replacing the Chassis Air Filter” section).

Step 11 Remove the chassis from the rack.

a. Using the side handles to support the weight of the chassis, remove the screws that attach the chassis rack mount flanges and the side rack mount brackets to the rack posts.

b. Carefully lift the chassis out of the rack and set it aside.

c. Use the rear handle on the Cisco ASR 9922 Router to push the chassis out of the rack and onto an adjacent pallet jack for transport.


 

Installing a Replacement Chassis in the Equipment Rack

Follow these steps to install the replacement chassis and components in the equipment rack:


Step 1 Install the new chassis in the rack (see the “Rack-Mounting the Router Chassis” section).

Step 2 Install the power modules (see the “Removing and Replacing Power System Components” section).
