7. Press the UPD/INIT pushbutton on the SYSCTL circuit pack.
Activated telemetry points: None.
8. Disconnect the optical fiber cable from the OLIU IN jack on one of the
OLIUs. The FAULT LED on the OLIU will flash.

should extinguish within several seconds.
All telemetry points should clear.
End-To-End Procedure
1. At the RT, provide a closure between miscellaneous (environmental) input
#1 and input common.
2. At the CO, verify that a closure is observed between miscellaneous (envi-
ronmental) output #1 and output common.
3. At the RT, remove the closure between miscellaneous (environmental)
input #1 and input common.
4. At the CO, verify that the closure is removed.
5. Repeat for each miscellaneous (environmental) input.
6. At the RT, turn off the AC power.
7. At the RT, verify that the AC power fail alarm appears in the alarm and sta-
tus report with the rtrv-alm
command.
8. At the RT, turn on the AC power.
9. At the RT, remove the fan fuses or fail the fan.
10. At all the RTs downstream, verify that the fan fail alarm appears in the
alarm and status report with the rtrv-alm command.
11. At the RT, replace the fan fuses or reset the fan.
12. At the RT, set the MN alarm closure (this is usually set by a failure of
non-DDM equipment, like removing a fuse from the fuse unit).
13. Also verify that the minor alarm appears in the alarm and status report with
the rtrv-alm command.
14. At the RT, remove the minor alarm failure.
15. At the CO, provide a closure between miscellaneous (environmental) input
#1 and input common.
16. At the RT, verify a closure is observed between miscellaneous (environ-
mental) output #1 and output common.
