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 will be
on solid), first do a PNC demand interchange via the reset pnc
interchange command. (The status pnc command can also be used 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), busyout the DS1 facility via the busyout ds1-facility command.
3. Replace the DS1 facility.
4. Release the DS1 facility via the release ds1-facility command.
Installing a DS1 Facility
Installing a DS1 facility is done in the following sequence:
1. Connect the facility.
2. Check the fiber link number via the list fibers command. Administer the
DS1 facility via the change fiber-link command. Change the Facility
Installed field from no to yes for the facility that is being installed.
3. Busyout the DS1 CONV circuit pack via the busyout board command.
4. Run the DS1 Facilities Connectivity test (#790) via the test board UUCSS
long command to make sure that the facilities are connected correctly.
5. Release the DS1 CONV circuit pack via the release board command.
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. Busyout the DS1 facility via the busyout ds1-facility command.
2. Check the fiber link number via the list fibers command. De-administer
the DS1 facility via the change fiber-link command. Change the
Facility Installed field from yes to no for the facility that is being
removed.
3. Disconnect the DS1 facility (or facilities in a critical-reliability system
configuration).
