Detecting Faulty Hardware

When power is applied to the chassis, power is sequentially applied to the Management I/O (MIO) cards, Management
I/O Universal (UMIO) cards, Data Processing Cards (DPCs), Data Processing Universal Cards (UDPCs), 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.

Important:

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.

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, UMIO and UDPC License Requirements in the ASR 5500 Installation Guide for additional
information on the effect licenses and card types have on the boot process.

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.

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