1-64 Maintenance overview
The system skips and tests the drawer on later passes of the BRT if
Single-drawer test The single-drawer test is for retest purposes if a
failure occurs during the system test. This test runs from the LCM MAP
level and is part of the TST DRWR command string. The RELAY option
allows the BRT to run without running the main DRWR test. The BRT does
not run unless you specify the RELAY option.
You ManB the drawer before the system runs the test. The system prompts
you if the drawer is InSv, ISTb, or SysB. The manual BRT cannot run on a
drawer where the LCM node is ManB, SysB, C-side busy (CBsy), or OffL.
The system displays a message that indicates that the request is invalid and
gives the current state of the node.
The single-drawer test displays a PM181 log with the results of the test. The
system also displays a response at the MAP terminal and, if necessary, a card
list that indicates the failed drawer.
If the system cannot run a single drawer test, the system does not set the
drawer ISTb. You can return the drawer to service to the previous state.
