IPMEDPRO (TN2602AP IP Media Resource 320)
Issue 1 June 2005 1401
1FAIL
The board is reporting that it is running half duplex with auto-negotiate (y).
Communication Manager is trying to negotiate the settings on the circuit
pack to match the administered settings and, under the above condition, it
is logging a fault. It could be argued that this is a false alarm, especially if
the link is operating correctly with no observable degradation of service.
Note: Do not immediately replace the board for this fault. There is a
mismatch between what is programmed in the board and administration on
Communication Manager.
CAT-3 wiring does not support 100Mbps data rates. Wiring between the
backplane and router must be CAT-5
Follow these steps to attempt to resolve the problem.
1. Change the ethernet options. Set the speed to 100Mbps with full
duplex. Set Auto (negotiate) to n. This should match the settings of the
connected router. If the router does not have the same capabilities, you
may have to adjust accordingly. The important thing is to make the
media processor (TN2302) and the connected router match.
Command steps to accomplish changes to Communication Manager
administration.
a) Enter get ethernet-options location to determine current
settings, both administered and actual.
b) Enter change ip-interface location (Enable Ethernet Port
field to n) to turn off the interface. Submit the command to disable the
interface.
c) Enter change ip-interface location change the Ethernet
Options fields as required. Submit the form.
d) Enter change ip-interface location (Enable Ethernet
Port field to y) to turn on the interface. Submit the command. to enable
the interface.
e) Enter get ethernet-options location to verify that Ethernet
options are the same in administration and on the board.
1. If service is normal and the alarm is causing concern, disable the test
and escalate the problem.
