When you issue the Technician Interface diags command to test and reboot a
specific module, the test and reboot process may take anywhere from 2 1/2
minutes to 10 minutes to complete, depending on the memory configuration of the
board. For example, when you issue the
diags command for a FRE-2 processor
module with 8 MB of DRAM, the process takes approximately 3 minutes to
complete. When you issue the
diags command for a FRE-2 processor module
with 32 MB of DRAM, the process takes approximately 10 minutes to complete.
Enabling and Disabling Diagnostics During the Power-Up Sequence
You can turn on and off the diagnostics for the AN/ANH or ARN platforms for
subsequent power cycles.
AN and ANH Power-Up Diagnostic Option
You can use the
set command on AN and ANH routers to disable or reenable the
power-up diagnostics.
set [ -P0 | P1 ]
Examples:
Pressing the Reset button on the back panel of the AN for more than 5 seconds
initiates a cold boot; power-up diagnostics execute even when disabled by the
set -P0 command.
ARN Diagnostics On/Off Option
For ARN platforms only, the Technician Interface
diags command supports an
option to enable or disable diagnostics, effective the next time you cycle power on
the router. Disabling the diagnostics results in a faster boot time, but leaves the
hardware components unverified.
The syntax for this option is as follows:
diags [- <on|off> ] [ <slot_id> ]
set -P0
The router skips power-up diagnostics at subsequent restarts.
set -P1
The router executes all power-up diagnostics at subsequent
restarts.
