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 5500 Installation Guide for comprehensive descriptions of the hardware components addressed

by these troubleshooting procedures.

•Detecting Faulty Hardware, on page 1

•Taking Corrective Action, on page 20

•Verifying Network Connectivity, on page 23

•Using the System Diagnostic Utilities, on page 26

•Generating an SSD, on page 29

Detecting Faulty Hardware

When power is applied to the chassis, power is sequentially applied to the Management I/O (MIO/UMIO/MIO2)

cards, Data Processing Cards (DPC/UDPC/DPC2/UDPC2s), Fabric and Storage Cards (FSCs), and System

Status Cards (SSCs).

Each PFU and 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.

Important

Licensing Issues

The system boot process is governed by StarOS licenses. During the startup process, each card performs a

series of Power-On Self Tests (POSTs) to ensure that the hardware is operational. These tests also verify that

the card meets all license requirements to operate in this chassis.

Refer to Chassis Universal License Requirements in the ASR 5500 Installation Guide for additional information

on the effect licenses and card types have on the boot process.

Troubleshooting

Using the CLI to View Status LEDs

Status LEDs for all cards can be viewed via the CLI by entering the Exec mode show leds all command.

[local]host_name#show leds all

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

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

Slot 02: Run/Fail: Green | Active: Off | Redundant: Green

Slot 03: Run/Fail: Green | Active: Off | Redundant: Green

Slot 05: Run/Fail: Green | Active: Green | Redundant: Green Master: Green

Slot 06: Run/Fail: Green | Active: Off | Redundant: Green Master:Off

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

Slot 11: Run/Fail: Green | Active: Green | Redundant: Green Status: Green |

Slot 15: Run/Fail: Green | Active: Green | Redundant: Green

Slot 16: Run/Fail: Green | Active: Green | Redundant: Green

Slot 17: Run/Fail: Green | Active: Green | Redundant: Green

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

command.

Checking the LEDs on the PFU

Each PFU has four LEDs along the top edge of its front panel. You must unsnap the top front cover from the

chassis to view these LEDs. Each LED is associated with one of the four -48 VDC power feeds connected to

the PFU.

Each LED on the PFU should illuminate blue for normal operating conditions.

Figure 1: PFU LEDs

The possible states for these LEDs are described in the following table. If the LED is not blue, use the

troubleshooting information below to diagnose the problem.

Verify that each circuit breaker is in the ON

position.

of its power planes.

None

Verify that the RTN and -48VDC lugs are

attached properly to the posts on the upper

rear of the chassis.

Verify that the ground lug is attached

properly.

Use a voltmeter to verify that the power

distribution panel is supplying the correct

voltage and sufficient current to the

terminals at the rear of the PFU.

Check the cables from the power source to

the rack for continuity.

If a power distribution panel (PDP) is

installed between the power distribution

frame (PDF) and the chassis, verify that its

circuit breakers 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.

Checking the LEDs on the MIO Card

Each MIO/UMIO/MIO2 is equipped with the following LEDs:

• Run/Fail

DPC Active LED States

The Active LED on the DDPC/UDPCPC or /DPC2/UDPC2 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 DPC/UDPCs or

/DPC2/UDPC2s are booted into standby mode. The system must then be configured as to which DPC/UDPCs

or /DPC2/UDPC2s should serve as redundant components (remain in standby mode) and which should function

as active components.
