SNI Off-board Destructive Facility Test (#756)

This test is destructive.

122 FAIL The SNI circuit pack cannot communicate with its neighbor via the circuit path.

1. Fix any on-board errors (SNI-BD, EXP-INTF, and/or DS1C-BD) against the

components of this fiber link by using display errors and display alarms

and following the associated repair procedures. (Use the list fiber-link

command to find the fiber link associated with this SNI. The display

fiber-link command can then be used to find the endp oints of the fiber link

and the DS1C circuit pack locations if this fiber link has a DS1 Converter

Complex administered .)

2. Enter display errors and follow the associated repair procedures for any

FIBER-LK entries for the fiber this SNI is administered on. Check list

fiber-link to determine the administered fiber.

3. If this fiber link ha s a DS1 converter complex ad ministered, enter display

errors and display alarms and follow the associated repair procedures

for any off-board DS1C-BD or DS1-FAC entries for either of the DS1C

boards administered or for the DS1 facilities associated with either of the

DS1C boards administered.

4. Replace this SNI.

PASS The SNI passed the sni circuit path test.

0NO

BOARD No board was detected by the test.

1. Check that board is properly translated and inserted.

2. Run the test again. If it fails, reset the board. An SNI should be reset

instead of reseating the circuit pack. The reset board command should

almost never be used on an SNI. It may be necessary to use the reset

board command if the SNI circuit pack gets into a mode where it cannot

communicate with soft ware. If an SNI with active errors and alarms is reset,

the errors and alarms may take a while to come back, therefore the reset

board command can mask real problems.

3. Run the test again. If it fails, the ID chip on board may b e bad. Replace the

board and retest.
