Troubleshooting

This chapter provides information and instructions for using the system command line interface (CLI) for

troubleshooting any issues that may arise during system operation.

Refer to the ASR 5000 Installation Guide for comprehensive descriptions of the hardware components

addressed by these troubleshooting procedures.

Detecting Faulty Hardware

When power is applied to the chassis, power is sequentially applied to management cards, application cards

and line cards.

Each PFU, application and line card installed in the system incorporates light emitting diodes (LEDs) that

indicate its operating status. This section describes how to use these status LEDs to verify that all of the

installed components are functioning properly.

As the system progresses through its boot process, some cards will not exhibit immediate LED activity.

Allow several minutes to elapse after a reboot is initiates before checking the LEDs on the various cards

to verify that the boot process has successfully completed.

Using the CLI to View Status LEDs

The status of application and line card LEDs can be viewed through the CLI by entering the show leds all

command in Exec mode.

[local]host_name#show leds all

The following displays a sample of this command's output.

Slot 01: Run/Fail: Green | Active: Off | Standby: Green

Slot 08: Run/Fail: Green | Active: Green | Standby: Off

Status: Green | Service: Off |

Slot 09: Run/Fail: Green | Active: Off | Standby: Green

Status: Green | Service: Off |

Slot 12: Run/Fail: Green | Active: Green | Standby: Off

Slot 14: Run/Fail: Green | Active: Green | Standby: Off

Slot 17: Run/Fail: Green | Active: Green | Standby: Off

Slot 24: Run/Fail: Green | Active: Green | Standby: Off

Slot 25: Run/Fail: Green | Active: Off | Standby: Green

Slot 30: Run/Fail: Green | Active: Green | Standby: Off

Slot 33: Run/Fail: Green | Active: Off | Standby: Off

Slot 40: Run/Fail: Green | Active: Green | Standby: Off

The status of the two Power Filter Units (PFUs) can be viewed by entering the show power chassis command

in the Exec mode.

Checking the LED on the PFU

Each PFU has a single status LED labeled POWER.

This LED should be green for normal operating conditions.

Figure 1: PFU LED Location

The possible states for this LED are described in the following table. If the LED is not green, use the

troubleshooting information below to diagnose the problem.

are set to ON.

If a PDP is installed between the PDF and the chassis, check the cables

from the PDP to the chassis for continuity.

If all of the above suggestions have been verified, then it is likely that

the PFU is not functional. Please contact your service representative.

Packet Processing Card Active LED States

The Active LED on a packet processing card indicates that the software is loaded on the card and that the card

is ready for operation. When the system first boots up, all installed packet processing cards are booted into

standby mode. The system must then be configured as to which packet processing cards should serve as

redundant components (remain in standby mode) and which should function as active components.

The possible states for this LED are described in the following table. If the LED is not green, use the

troubleshooting information in the table to diagnose the problem.

The first time power is applied to the system, all of the packet processing cards

should be booted into the standby mode. Therefore, this LED should be off.
