If the Extended POST has completed successfully:
Ÿ
The green LEDs for the system (OK) and for any port with wrap plugs
will be on.
Ÿ
The port amber LEDs will be off (or blinking if no wrap plug is installed).
For the 12x models, the system (OK) green LED blinking with the system
amber LED on indicates that the service port external wrap test has failed.

To run the extended POST again, press the reset button after 2 minutes.
6
To end extended POST, power off the IBM 2210 by unplugging the power
cord from the power outlet.

Be sure to remove any wrap plugs from the IBM 2210 before applying power
to reload the router. Do not leave wrap plugs on unused ports.
| Above references to wrap plugs do not apply if an internal wrap is performed during
| extended POST. An internal wrap is performed if the following levels of boot code
| are installed:
|
Ÿ
IBM 2210 12x models if you have the boot code level 1.62 or higher.
|
Ÿ
IBM 2210 models 1S4, 1S8, 1U4, and 1U8 if you have the boot code level 1.32
| or higher.
|
Ÿ
IBM 2210 x4x models if you have the boot code level 2.40 or higher.
Operational Diagnostics
To run the menu-driven operational diagnostics, attach an ASCII terminal to the
IBM 2210. If no terminal is available, run the Extended POST, as described in
“Extended POST” on page 3-1.
If an ASCII terminal is already attached to the IBM 2210, continue with “Running
the Diagnostics.” Otherwise, go to Appendix A, “Access Methods and Attaching an
ASCII Terminal” on page A-1 for instructions.
Note: Because running the diagnostics requires complete control of the IBM 2210,
be sure to notify the customer’s system administrator before shutdown.
Running the Diagnostics
You can execute the diagnostics:
Ÿ
Immediately after attaching an ASCII terminal
Ÿ
When an ASCII terminal is already attached and the router user interface is in
operation.
Immediately After Attaching an ASCII Terminal.: To start the diagnostics imme-
diately after attaching a terminal:
1
If the IBM 2210 is not already unplugged, unplug it from the power outlet.
2
To start the diagnostics, plug the power cord into the outlet and, when the
green system LED is on and the amber system LED is blinking, or both
green and amber system LEDs are blinking, press Ctnl-c.
