Cabling Devices
Media Requirements
Incorrect cabling is often the cause of network performance problems. The
next two pages discuss the requirements.
100Base-TX
The 100Base-TX Fast Ethernet specification requires that you use
CAT 5 UTP cabling to operate at 100Mbps. You’re limited to 100 meters
between any two devices. 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.
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 of cable between any two
devices.
100Base-FX
The fiber ports of the 535T switch let you connect to a switch up to 400
meters (hubs up to 160m) away at half-duplex or up to 2 km at full-duplex.
Use 62.5/125µm multimode fiber optic cable with an SC-type or MTRJ
fiber optic connector.
Straight-through vs. Crossover Cables
Switch ports are wired MDI-X, so use a straight-through cable when
ccvonnecting to a workstation or server. (Network adapter cards are wired
MDI, not MDI-X.) For direct connection to another MDI-X port, use a
crossover cable. Here are the pin arrangements for the switch’s Ethernet port
and the typical RJ-45 connector.
