Connect the twisted pair segment to the switch by inserting the RJ45 connector on the
twisted pair segment into the desired RJ45 port (for example, Port 8).

Verify that a link exists by checking that the Link/Activity LED is ON (solid green or
blinking green). If the Link/Activity LED is OFF, perform the following steps until it is
on:
a.
Verify that the cabling being used is Category 5 or better with an impedance
between 85 and 111 ohms with a maximum length of 100 meters (328 feet).
b. Verify that the device at the other end of the twisted pair segment is on and
properly connected to the segment.
c.
Verify that the RJ45 connectors on the twisted pair segment have the proper
pinouts and check the cable for continuity. Typically, a crossover cable is used
between hub devices. A straight‐through cable is used to connect between
switches or hub devices and an end user (computer). Refer to
and
for four‐wire RJ45 connections. Refer to
for eight‐wire RJ45 connections.
d. Ensure that the twisted pair connection meets the dB loss and cable specifications
outlined in the Cabling Guide. Refer to “
” on page xvi for
information on obtaining this document.
4.
If a link is not established, contact Enterasys Networks. Refer to “
page 1‐8 for details.
Repeat all steps above until all connections have been made.
