Connecting A Twisted Pair Segment To The Nac Controller Pep - Enterasys 2S4082-25-SYS Hardware Installation Manual

Connecting to the Network
Figure 4‐5 shows connecting a twisted pair segment to the 2S4082‐25 module. It is assumed that
the chassis power is turned on to provide power to the module. Refer to Figure
follows:
1. Ensure that the device connected to the other end of the segment is powered ON.
2. Connect the twisted pair segment to the module by inserting the RJ45 connector on the
twisted pair segment into the appropriate RJ45 port connector.

3. Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing amber,
blinking green, or solid green). If the RX LED is OFF and the TX (Transmit) LED is not
blinking amber, perform the following steps until it is on:
a.
b. Verify that the cabling being used is Category 5 UTP with an impedance between 85 and
c.
d. Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts and

To view the receive and transmit activity on a group of segments, press the GROUP
SELECT button (see Figure
time the GROUP SELECT button is pressed, the GROUP LED lights up in sequence,
indicating which Group is selected. The receive and transmit activity for that group of
segments is then indicated by the RX and TX LEDs for each segment.
111 ohms. For the port to operate at 100 or 1000 Mbps, Category 5 cabling must be used
and installed properly.
Verify that the device at the other end of the twisted pair segment is on and properly
connected to the segment.
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 Figure 4‐6 and Figure
to Figure 4‐8 and Figure
4‐5) to step to the group of interest (Groups 1 and 2). Each
