Procedure 8.24: ISLU FAN ALARM TESTS
OVERVIEW
CAUTION:
Any equipment that is taken out of service by these fuse/alarm tests must be allowed to recover before
proceeding with this procedure.
This procedure verifies that the major alarm condition caused by an inoperative fan in an ISLU drawer can be
detected and that the proper indications are given.
The following tests should be performed on
each
fan of each ISLU drawer. Testing each alarm in this procedure will
verify the hardware retire (reset button) and the software retire (input message).
Only one fan can be tested in the ISLU at a time. Each ISLU drawer contains three (3) fans (A, B, and C) and each
fan shares a fuse with one of the Line Groups (LG) in the drawer.
Table 8.24-1 indicates the ISLU Line Group fuse relationship. When you select an ISLU Line Group fuse, a fan in
the base of the drawer is also selected.
