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.

Replacing Cisco ASR 9000 Series Router Components

Field Replaceable Units

The backplane, midplane (only for Cisco ASR 9906 Router and Cisco ASR 9910 Router), PEM, and BPID

cards are not FRUs but are field serviceable.

Note

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 (LCs), 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.

Never unplug all the fan trays at the same time.

Caution

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.

Note

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 cards, RP cards, FCs, and

LCs. 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.

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.

Note

Powering Off the Router

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.

Caution

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

Replacing Cisco ASR 9000 Series Router Components

Online Insertion and Removal

Procedure

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.

In the Cisco ASR 9006 Router, Cisco ASR 9010 Router, Cisco ASR 9904 Router, Cisco ASR 9906 Router,

and Cisco ASR 9910 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.

Note

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.

Caution

This table describes the air filter locations for the Cisco ASR 9000 Series Routers.

Follow these steps to replace an air filter:

Procedure

Step 1 For the Cisco ASR 9006 Router, Cisco ASR 9010 Router, Cisco ASR 9904 Router, Cisco ASR 9906 Router,

and Cisco ASR 9910 Router, choose the procedure for your router:

• For the Cisco ASR 9010 Router, Cisco ASR 9906 Router, and Cisco ASR 9910 Router, remove the air

filter by simply sliding it out of the chassis.

If the accessory grill has been installed on the front of the Cisco ASR 9010 Router, remove it

from the front of the chassis by simply pulling on the grill until it comes loose. See the Installing

Base Chassis Accessories on the Cisco ASR 9010 Router, and Figure 2 for information about

the accessory grill.

• For the Cisco ASR 9006 Router and Cisco ASR 9904 Router, loosen the thumb screw that secures the

filter to the chassis, and then slide the air filter out of the chassis.

Step 2 For the Cisco ASR 9922 Router and Cisco ASR 9912 Router, remove the three air filters by pulling them off

the front of the chassis (Cisco ASR 9922 Router Chassis Air Filters) and (Cisco ASR 9912 Router Chassis

Air Filter ). Then, for each filter, loosen the thumb screws, rotate the inner frame out, and replace the foam

media (Removing the Cisco ASR 9922 Router Chassis Center Air Filter—Version 1 and Removing the Cisco

ASR 9922 Router Chassis Side Air Filter —Versions 1 and 2).

In the Cisco ASR 9922 Router (version 2 air filter) the center air filter, shown in Cisco ASR 9922

Router Chassis Center Air Filter—Version 2, does not contain replaceable foam media. The left

and right air filters are the same as version 1 and contain replaceable foam media.

Step 3 Visually check the condition of the air filter and/or its foam media to determine whether to install a new

replacement filter or foam media.

Step 4 Install the new air filter.

• For the Cisco ASR 9010 Router, Cisco ASR 9906 Router, and Cisco ASR 9910 Router, slide the new

air filter into the air filter door (honeycomb side up).

Replacing Cisco ASR 9000 Series Router Components

Replacing the Chassis Air Filter

• For the Cisco ASR 9006 Router and Cisco ASR 9904 Router, tighten the thumb screw to secure the filter

to the chassis.

• For the Cisco ASR 9922 Router (version 1 air filter) and Cisco ASR 9912 Router, tighten the thumb

screws that attach the inner frame to the air filter and re-attach the three air filters to the front of the

chassis. For the Cisco ASR 9922 Router (version 2 air filter) tighten the thumb screws that attach the

inner frame to the left and right air filters only. Attach the new center air filter, with arrows pointing

upwards, and re-attach both side filters to the front of the chassis.

For the version 2 air filter on the Cisco ASR 9922 Router, the center does not have thumb screws

because it does not have replaceable foam media.

Note

Align and seat the door carefully to avoid damaging the EMI-preventive gaskets on the door. The

air filter door must be closed and secured at all times to maintain correct EMI performance.

Caution

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 9906 Router, 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)

Removing a Fan Tray

Follow these steps to remove and replace the fan trays:

Never unplug all the fan trays at the same time.

Caution

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.
