To view the receive and transmit activity on a group of segments, press the
GROUP SELECT button
(Groups 1 through 3 on the 7G4202‐60, or Groups 1 through 5 on the 7G4282‐41).
Each time the GROUP SELECT button is pressed, a 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

must be used.
Verify that the device at the other end of the twisted pair segment is on and
properly connected to the segment.
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 Figure
Figure 3‐7 for four‐wire RJ45 connections. Refer to Figure 3‐8 and Figure
eight‐wire RJ45 connections.
