7 Log and fault reports

XSM maintenance interface

There are several logs associated with Intelligent Peripheral Equipment (IPE).
Some example fault reports are listed and described in this section, following
an overview of the Extended System Monitor (XSM) maintenance interface as
it pertains to log and fault reports.

XSM unsolicited fault reports

When a master XSM detects a fault in the IPE column (IPEC) that it monitors,
or receives a fault message from one of its slaves during polling, a fault
message is sent to the SL-100 Centeral Controller (CC). The XSM SLLNK
interface receives the message from the Multi-Protocol Controller RS-232C
port and routes the message to CC Peripheral Module (PM) maintenance for
processing.
If the message is reporting a failure for one IPE within an IPEC (the source of
the problem is identified in the message), that IPE is queried using
conventional CC-PM messaging. If the IPE responds to the query message, a
PM log is generated and the state of the IPE is changed to in-service troubled
(ISTb).
For example, the following ISTb conditions can be displayed using the
QUERYPM FLT command at the IPE level of the MAP display when ISTb is
posted.

If, on the other hand, the IPE fails to responds, the IPE is marked system busy
(SYSb) and PM logs are generated reporting the failure. If the message from
the XSM is reporting a failure for all IPEs in an IPEC (such as circuit breaker
activated), each IPE is queued for its status and each IPE is handled as if the
failure occurred for each IPE individually.

XSM "fault cleared" reports

When a master or slave XSM detects that a previously reported fault condition
has been cleared, a corresponding status change report is sent to the MSL-100
