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. To view the receive and transmit activity on a group of segments (Groups 1 through 4),

press the GROUP SELECT button

➂ to step to the group of interest. Each 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.

b. Verify that the cabling being used is Category 5 UTP with an impedance between 85 and

111 ohms. If the port is to operate at 100 Mbps, category 5 cabling must be used.

c. Verify that the device at the other end of the twisted pair segment is on and properly

connected to the segment.
