Connection Guidelines
General
• The 470T switch is can auto-negotiate port duplex. It can operate at
half-duplex or full-duplex at 100Mbps, and full-duplex at 1000Mbps.
The switch matches the highest possible speed (up to 1000Mbps) of an
attached device.
• The 470F operates at full-duplex and at 1000Mbps.
Cabling
• Use Category 5 unshielded, twisted-pair (CAT 5 UTP) cable to connect
1000Mbps or 100Mbps devices to the switch.
• Limit the cable length between devices to 100 meters (330 feet) for
copper wire.
• Use a straight-through cable to connect the switch to a server or
workstation.
• To connect to another switch or hub, use a crossover cable.
Straight-through vs. Crossover Cables
Switch ports are wired MDI-X, so use a straight-through cable to connect to
a workstation or server (network adapter cards are wired MDI). To connect
to another MDI-X port, use a crossover cable. The following pin
arrangements are for the switch’s Ethernet port and the typical RJ-45
connector. The wiring diagrams illustrate how to wire a straight-through and
crossover cable for 100Mbps and 1000Mbps devices.
Straight-Through UTP cable (100Mbps)
Switch (MDI-X) Adapter (MDI)
NOTE
Use certified Category 5 cables to
connect 1000Mbps devices to the
switch.
