Verifying the SWAN Concentrator Hardware

The OSM Service Connection or TSM Service Application provide the following test

actions for a SWAN communications line interface processor (CLIP):

How to Run a Test Action

The OSM Service Connection is similar to the TSM Service Application, in that you can

locate and select the CLIP you want to test and launch the appropriate action from the

Actions dialog box. An enhanced feature in OSM is the Multi-Resource Actions dialog

box. It enables you to select any or all resources of the same type (such as SWAN

CLIPs) and perform an action on them simultaneously. For more information, see the

OSM Service Connection online help.

Test Action Description

Test Primary Path Access Tests two-way access to the primary path to a selected

CLIP. If you suspect a problem in the primary path to a

CLIP, use this test action.

Test Backup Path Access Tests two-way access to the backup path to a selected

CLIP. If you suspect a problem with the backup path to

the CLIP, use this test action.

Test Full Path Access Tests two-way access to a selected CLIP using both the

primary and backup paths (equivalent to running both

the Test Primary Path Access and Test Backup Path

Access test actions). If you suspect a problem in both

paths to CLIP, or if you do not know which path might

have a problem, use this test action. If this test action

fails, use the Test Basic Online test action.

Test Basic Online Runs an online test to determine if a selected CLIP is

functional and tests two-way access to both the primary

and backup paths to a selected CLIP (equivalent to the

Test Full Path Access test action but also tests the

hardware registers). If this test action fails, use the Test

Verify test action.

Test Verify Runs the power-on self-test (POST) for a selected CLIP.

During POST, status light-emitting diodes (LEDs) light.

These status LEDs and their functions are described in

Table 4-1

on page 4-16 and Table 4-2 on page 4-17.

You must stop the CLIP you are testing and shut down

any active communications lines using the CLIP before

executing the Test Verify test action. For more

information, see Preparing a SWAN CLIP for the OSM

or TSM Test Verify Test Action or Firmware Update on

page 4-19.
