9-850FIBER-LK (Fiber Link)
9
Notes:
a. The fiber is in frame, but no communication exists to the neighbor.
b. This is the normal state for an active EPN EI circuit pack that is also the
bus master (expansion archangel) in the EPN.
c. This is the normal state for an active EI circuit pack that is not the bus
master (expansion archangel) for an EPN. This applies only in the direct
connect configuration where the EI circuit pack in an EPN connects via a
fiber link to an EI circuit pack in the other EPN. This state also applies for
an active EI circuit pack located in the PPN.
d. This is the normal state for a standby expansion Interface circuit pack in
both the PPN and EPNs.
For more details about how the Expansion Interface circuit pack error codes
relate to the LED states, see the EXP-INTF section.
Notes:
a. A Fiber is out of frame or a fiber loss of signal condition exists.
b. DS1 CONV/fiber endpoint communication is down.
