CONNECTING TWISTED PAIR SEGMENTS TO
RJ-45 PORTS
To connect a workstation or other device to the MR9:
1.
Use a twisted pair segment with RJ-45 connectors at each end.
Connect one end of the cable to any RJ-45 port on the MR9.
Connect the other end of the segment to a 10BASE-T device.
Note: If the polarity of the twisted pair segment is reversed, the MR9
senses the mismatch and automatically reconfigures internal
operation to allow the repeater to operate. This automatic detection
and correction feature is a standard feature of Cabletron Systems’
10BASE-T products.
2.
Verify that the LNK LED for the applicable repeater port is lit. If
the LED is not lit, perform each of the following steps:
a.
Check that the 10BASE-T device at the other end of the
twisted pair segment is turned on.
b.
Disconnect the RJ-45 connector from the repeater.
c.
Check the pin configuration of the segment RJ-45
connector.
Note: If using port 9, check the configuration switch to ensure that it
is in the proper position for the connector you are using. For normal
installations, select the cross-over (X) configuration.
d.
Check the segment for continuity.
e.
Reconnect the RJ-45 jack to the RJ-45 port of the MR9.
