Connection Procedure
To attach a lobe cable segment to a MicroMMAC-T lobe port, insert the
RJ45 connector on the cable into an RJ45 lobe port on the
MicroMMAC-T, as shown in
Figure 4-4 .
The associated Port Status LED lights:
• Green when the port is enabled and the station is inserted into the ring.
•
Red when the port is disabled and the station is inserted into port.
•
Red and blinks when the port is disabled due to a ring speed error
(station tried to insert into the ring at the wrong ring speed).
Figure 4-4 Connecting To A Lobe Port
If the associated Port Status LED lights red or does not light, perform the
following steps to resolve the problem:
1.
Check that the device at the other end of the twisted pair segment has
power, and that the network interface driver is initialized.
2. Verify the RJ45 connector pinouts on the twisted pair segment.
3.
Verify that you are using the correct cable type.
4.
Check Local Management to ensure that the port is enabled.
