Incorrect cabling is often the cause of network configuration problems.
Read the next two pages if you’re unsure of your requirements.

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.

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.

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 the daisy-chain
port or a crossover cable. Here are the pin arrangements for the hub’s
Ethernet jack and the typical RJ-45 connector.

A quick way to check a cable’s link integrity is to plug one end into the
daisy-chain port, the other end of into port 2, and check the Activity LEDs
for ports 1 and 2. If the LEDs are on, you have a functioning straight-
through cable.

If the LEDs are off, remove the cable from the daisy-chain port and
reinsert it in port 1. If the Activity LEDs for ports 1 and 2 are on, you
have a functioning crossover cable.
