DS1-FAC (DS1 Facility)
For a critical-reliability system (PNC duplication):
This procedure is nondestructive.
1. If the DS1 facility to be replaced is on the active PNC (its amber LED is on solid), use
reset pnc interchange to do a PNC demand interchange. Use status pnc to
determine the active PNC.
2. When the DS1 facility to be replaced is on the standby PNC (if the DS1 facility was originally
on the standby PNC or after the PNC interchange has finished), use busyout
ds1-facility to busyout the DS1 facility.
3. Replace the DS1 facility.
4. Use release ds1-facility to release the DS1 facility.
Installing a DS1 Facility
To install a DS1 facility:
1. Connect the facility.
2. Use list fiber-link to check the fiber link number.
3. Use change fiber-link to administer the DS1 facility via the command. Set the
Facility Installed field to y for the facility that is being installed.
4. Use busyout board to busyout the DS1 converter circuit pack.
5. Use test board location long to run the DS1 Facilities Connectivity Test (#790), to
ensure that the facilities are connected correctly.
6. Use release board to release the DS1 converter circuit pack.
Removing a DS1 Facility
Removing a DS1 facility is service disrupting in any system configuration, because the DS1
facility administration is similar on both sides of the PNC on critical-reliability systems.
This procedure is destructive.
1. Use busyout ds1-facility to busyout the DS1 facility.
2. Use list fiber-link to check the fiber link number.
3. Use change fiber-link to administer the DS1 facility. Set the Facility Installed
field to n for the facility that is being removed.
4. Disconnect the DS1 facility (or facilities in a critical-reliability system configuration).
