Installing the Switch

3. Problem 3:

The MDI/MDI-X slide switch for TX is on the wrong setting.

❑

Solution 3:

— Verify that you are using a known good cable, reposition the MDI/

MDI-X switch, and check that the Link LED is lit.

4. Problem 4:

There is signal loss between the switch and one of the attached network

nodes.

❑

Solution 4:

— Make sure the distance between the switch and the connected

network device does not exceed 100 meters (328 feet). (UTP is half-

or full-duplex.)

— 412 meters (1,351 feet) for multi-mode fiber cable (half-duplex FX

operation/2 kilometers (1.2 miles) for full-duplex FX operation) See

Table 8, “Technical Specifications,” on page 23 for correct distances

for 10Base-T, 100Base-TX and 100Base-FX cable lengths.

Make sure you are using Category 5 cable when operating at 100 Mbps.
