Troubleshooting
1. Remove any transformer in position T4.
2. Install the transformer into position T4A.
Note: Channel 2 is set at the factory to operate with Ethernet or IEEE 803.2
10BASE5.
Setting Channel 2 for Thin Ethernet Operation:
1. Remove any transformer in position T2A.
2. Install the transformer into position T2.
Setting Channel 2 for Ethernet or IEEE 802.3 10BASE5 Operation:
(Channel 2 Factory Setting)
1. Remove any transformer in position T2.
2. Install the transformer in position T2A.
When the power is first applied, the green PWR and red DIAG LEDs will
be lit. Each of the four green network activity LEDs will be OFF.
The CentreCOM MAC Layer Bridge executes a comprehensive set of
diagnostics when the power is first applied. The red DIAG LED will flash
ON for each test that is executed. After successfully executing the
diagnostic tests, the DIAG LED will be turned OFF. If any tests fail, the
DIAG LED will remain ON. In the latter case, the bridge should be
resumed for service.
Under normal operation, the four green activity LEDs will reflect the
reception and transmission of data packets on each channel. The activity
LEDs have the following meaning (Table 4):
Name
TX1 Channel 1 is forwarding a packet
RX1 Channel 1 is receiving a packet
TX2 Channel 2 is forwarding a packet
RX2 Channel 2 is receiving a packet
The CentreCOM MAC Layer Bridge contains software that allows two or
more bridges to interconnect the same two networks. This feature allows
the use of backup bridges that take over when a bridge or its network
connection fails. The bridges communicate with each other to implement
this feature. Because of this, the activity LEDs will always blink about
once every few seconds, even if there is no other network activity.
The next thing to check is that both network connections are firmly made
to the bridge and to the network.
