Cabling Devices
Media Requirements
Incorrect cabling is often the cause of network configuration problems.
Read the next two pages if you’re unsure of your requirements.
100Base-TX
The 100Base-TX Fast Ethernet specification requires that you use
CAT 5 UTP cabling to operate at 100Mbps. If you use lower grade cabling
(CAT 3 or CAT 4), you may get a connection, but will soon experience data
loss or slow performance. You’re limited to 100 meters between any two
devices.
10Base-T
The 10Base-T Ethernet specification allows you to use CAT 3, CAT 4, or
CAT 5 UTP cabling. You’re limited to 100 meters between any two devices.
100Base-FX
The optional Fiber Module lets you connect to a switch, bridge, or router up
to 160 meters away at half-duplex or up to 2 km at full-duplex. Use 62.5/
125µ multimode fiber optic cable with an SC-type fiber optic connector.
Straight-through vs. crossover cables
Hub ports are wired MDI-X, so use a straight-through cable when
connecting to a workstation or server (network adapter cards are wired
MDI). For direct connection to another MDI-X port, use a crossover cable.
Here are the pin arrangements for the hub’s ethernet jack and the typical
RJ-45 connector.
