RLC description
LED indicators
Four faceplate LED indicators monitor the basic health, transmit activity,
receive activity, and Ethernet collisions on the RLC. The illustration on page 7
shows the 16- and 32-port RLC faceplates with the function of each LED
labeled.
Maintenance
The red Maintenance LED on the faceplate indicates the basic health of the
RLC, as with all other IPE line cards. Under normal conditions, the Maintenance
LED lights under firmware control at power up and blinks three times after a
successful self-test. This LED remains lit until the host PBX enables the RLC,
then it goes out. If the host PBX disables the RLC, the Maintenance LED comes
on and stays on.
Other characteristics of the Maintenance LED include:
If the Maintenance LED comes back on after the RLC passes its self-test,
ensure that the card is enabled. (Refer to the host PBX documentation for
the correct procedure.) If the RLC is enabled and the Maintenance LED
remains on, there is a problem at the host PBX.
If the Maintenance LED blinks repeatedly at one-second intervals, reseat
the card at the host PBX by lifting the ejector tabs outward and pulling the
RLC toward yourself. This action breaks the connection between the RLC
and the backplane.
After breaking this connection, re-insert the card completely into its slot. If
the RLC still does not complete a successful self-test, it must be replaced.
Ethernet Transmit
The green Ethernet Transmit LED indicates the transmission of Ethernet packets
by the RLC.
Ethernet Receive
The green Ethernet Receive LED indicates the reception of Ethernet packets by
the RLC.
