Daisy Chain Cable
1
The RCIM IV uses a fiber optic serial synchronization cable with SFP (small form-factor
pluggable) connectors (part no. HS002-3CBL-xx) to connect RCIM IVs in an RCIM
chain. The serial data on the cable includes parity and framing information which allow
cable problems to be detected. Polling is done continuously and messages that report the
status of the RCIM IV daisy chain cables are output when an error condition is detected.
Messages indicating problems will appear on the systems directly connected by a failing
link.
The serial cables are point to point connections. The “input” cable refers to the cable going
upstream towards the master RCIM. The “output” cable is the downstream connection
away from the master.
RCIM: Input cable disconnected.
RCIM: Input cable connected.
RCIM: Input cable connected but not synchronized.
RCIM: Input cable unsynchronized.
RCIM: Input cable O.K.
RCIM: Output cable disconnected.
RCIM: Output cable connected.
RCIM: Output cable connected but not synchronized.
RCIM: Output cable unsynchronized.
RCIM: Output cable O.K.
RCIM: Cable error on input cable.
RCIM: Cable error on output cable.
The “disconnected” and “connected” messages will only occur based on whether an SFP
is installed in the appropriate cage of the RCIM IV.
They will not occur when the optical cable is inserted or removed. They should not occur
during normal operation unless the SFP is not installed correctly or it is malfunctioning.
The “not synchronized” and “unsynchronized” messages indicate that the cable is not
answering attempts to communicate. These messages will occur when the optical cable is
installed or removed. They will also occur when a connected system is powered off.
