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:

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

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.
For the RSP/RP to communicate properly to a power module in a power tray, input power to at least one of
the power modules in the power tray should be present.
Note
This section contains procedures on how to remove and install AC and DC power modules used in the Cisco
ASR 9000 Series Routers.
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

Step 4 Repeat Step 1 through Step 3 for the other power tray, if installed.
It is not necessary to disconnect all power from the router to replace components, including power
modules. See Removing and Replacing Power System Components, on page 12.
Caution
Disconnecting DC Power
If it becomes necessary to disconnect all DC power from the router, follow these steps (Figure 2 for version
1 DC power, Figure 3 for version 2 DC power, or Figure 3 for version 3 DC power):
Procedure
Step 1 Set the power tray switch to the STANDBY (0) position.
Step 2 Power OFF (0) the circuit breaker assigned to the DC power source you are disconnecting.
To ensure that power remains off while you are performing this procedure, lock-out/tag-out the
circuit breaker switch in the OFF (0) position until you are ready to turn it on.
Caution
Step 3 Remove the clear plastic safety covers that fit over the DC power connection terminal studs.
To prevent injury and damage to the equipment, always remove the source DC power cables and
ground from the power tray terminals in the following order : (1) negative (–), (2) positive (+), (3)
ground.

Disconnecting DC Power

Step 4 Disconnect the DC power cables from their terminals in the following order and note the color of each cable
(Figure 2 for version 1 DC power, Figure 3 for version 2 DC power, or Figure 3 for version 3 DC power):
a) Negative (PWR) cables first.
b) Positive (RTN) cables next.
c) Ground cable last.
Step 5 Repeat Step 1 through Step 4 for the other power tray, if installed.
This procedure describes how to disconnect DC power from all power modules in a single DC
power tray. The procedure is the same for each DC power tray, if more than one is installed.
Note
If only one power tray is installed, performing the following procedure turns off all power to the
router.
Caution
Reconnecting DC Power
Follow these steps to reconnect DC power to a DC power tray:
Procedure
Step 1 Set the power switch to the OFF (0) position.
Step 2 Check that the circuit breaker assigned to the DC power source you are reconnecting is powered OFF (0).
Step 3 Reconnect the DC power cables in the following order:
a) Ground cables first.
b) Positive (RTN) cables next.
c) Negative (PWR) cable last.
d) Repeat Step 1 through Step 3 for the other power tray (Cisco ASR 9010 Router only)
To prevent injury and damage to the equipment, always attach the ground and source DC power
cable lugs to the power tray terminals in the following order: (1) ground to ground, (2) positive
(+) to positive (+), (3) negative (–) to negative (–).
Caution
Do not overtighten the nuts that secure the DC power cables to the power tray terminals. The
nuts should be tightened using the 7/16 hex socket and torque wrench to a torque of 45 to 50
in-lb.
Caution
Step 4 Replace the clear plastic safety covers over the DC power connection terminal studs and tighten the screws.
Step 5 Set the DC power source circuit breaker to ON (1).
Step 6 Set the power tray switch to ON (1).
Use this procedure only when reconnecting power to all power modules in a system that is powered
down completely.
