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