Connection Guidelines

General
• The 470T switch is capable of auto-negotiating port duplex. It can
operate at half- or full-duplex at 100Mbps, and full duplex at
1000Mbps. The switch matches the highest possible speed of an
attached device.
• The 470F operates at full-duplex and at 1000Mbps.
Cabling
• Use Category 5 unshielded twisted-pair (CAT 5 UTP) cable when
connecting 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. 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.
