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 Critical Reliability System
configuration).
DS1 Interface Options
The following DS1 Interface options must be set with fiber link administration. To
set the values, check the number of the fiber link via the
list fibers
command.
Execute the
change fiber-link
command and set the following fields:
Facility Installed
This field determines if the DS1 facility is installed. The field is set to
yes
if the
facility is installed.
For TN574 DS1 CONV boards, facility A must be installed before the others.
Facilities B, C and D can then be installed in any order desired since the primary
facility can reside on any of the four facilities.
For TN1654 DS1 CONV boards, facility A must be installed first, then B, then C or
D. This is required since the primary facility can only reside on facilities A or B.
