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:

To view the receive and transmit activity on a group of segments, press the GROUP
SELECT button (see Figure
7G4202‐72, or Groups 1 through 5 on the 7G4282‐49). 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 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 3‐5 and Figure
