Led Matrix Display - Cisco ASR 9901 Hardware Installation Manual

Troubleshooting the Installation

LED Matrix Display

The LED matrix displays one row of four characters. The matrix becomes active when the CPU powers on
and displays the stages of the boot process, as well as displaying runtime information during normal operation.
If there are CAN Bus Controller problems, error messages are displayed.
LED Matrix Boot Stage and Runtime Display
The following tables describe the boot process and runtime display information for the RSP.
Not all of these messages are seen during a successful boot up process because the screen is updated too
quickly for the message to be visible. A failure detected during the boot up process results in the message
remaining visible indicating the stage where the boot up process stopped. When possible, the RSP logs the
failure information and reboots.
