NOTE: T he label for a discrete FIM is marked “Comm Active”. Current
labels for analog FIMs are marked “Comm A” and “Comm B”. Older
labels for analog FIMs were marked “Port A” and “Port B”.
NOTE: T he new FIM m ay be left in service in that socket; the failed F IM
should be removed immediately. The empty socket will provide for
another online replacement. Do not leave two F IMs plugged into an
online replacement style panel.
Multipoint I/O FIM Redundancy
Full FIM redundancy is provided when two FIMs are used. Two
communication lines are required, one for an odd numbered slot and
one for the next even numbered slot. The primary FIM is in the “F IM A”
socket and the r edundant FIM is in the “FIM B” socket. The redundancy
jumper(s) must be set at redundant to allow redundant operation. A
Redundant I/O Block (RIOB) must be configured to control operations.
Analog FIM redundancy requires that the jumpers at HD18 and HD19
on the Analog Termination Panel be set to the “R” position while
discrete FIM redundancy requires that the jumpers at HD2 on the
Discrete Termination Panel be removed.
The odd numbered slot address must be wired to FIM A, the “primary” FIM.
The even numbered slot must be wired to FIM B, the “secondary” FIM.
Primary (A) FIM Failure: If the primary F IM fails, the secondary FIM
takes over and assumes the duties of the primary. Normally the failed
FIM red LED goes ON and the green LED flashes. T he failed FIM
should be removed and replaced. As soon as the new F IM A powers
up, it assumes the duties of the primary F IM and F IM B returns to
secondary operation.
Secondary (B) F IM Failure: If the secondary F IM (B) fails, the primary
FIM (A) continues to operate. Normally, the failed F IM red LED goes ON
and the green LED flashes. The failed FIM B should be removed and
replaced. As soon as the new FIM B powers up, it resumes the duties of
secondary F IM.
