Attaching a Twisted Pair Segment to the TPRMIM-20/22
The TPRMIM-20 has nine RJ45 unshielded twisted pair ports (UTP) and the
TPRMIM-22 has twenty-one RJ45 UTP ports. The TPRMIM-20 and
TPRMIM-22 have a Polarity Correction and Detection feature which allows
packets to pass even if the polarity of the twisted pairs segment’s receive link is
reversed. A flashing LNK LED indicates reverse polarity.
To attach twisted pair segments to the network ports:
1.
Insert the RJ45 connector from each twisted pair segment into the desired
network port on the RMIM as shown in Figure 3-8.
Figure 3-8. TPRMIM-20/22 Network Ports
2.
At the device end of a segment, attach the segment to a 10BASE-T compliant
Ethernet device.
3.
Check that the Link light on the 10BASE-T Ethernet device and the LNK
LED on the TPRMIM are on. If the LEDs are not on, perform each of the
following steps until the LEDs are on:
a.
Check that the 10BASE-T device and the MMAC have power.
b.
Verify the cabling between the TPRMIM and the device.
c.
Check the cable for continuity.
If a link has not been established, contact Cabletron Systems Technical Support.
