Connecting to Devices

Connection Guidelines

General

•The Express 410T switch is capable of autonegotiating port speed and can operate at 10Mbps or 100Mbps per port. The switch matches the highest possible speed of an attached device.

•The Express 410T switch is capable of autonegotiating port duplex and can operate at half- or full-duplex.

•Configure the network so devices that talk to each other primarily are on the same segment. Each port is a single segment.

Cabling

•Use Category 5 unshielded twisted-pair (CAT 5 UTP) cable when connecting 100Mbps devices to the switch.

•Use Category 3, 4, or 5 unshielded twisted-pair (CAT 3, 4, or 5 UTP) cable when connecting 10Mbps devices to the switch.

•Limit the cable length between devices to 100 meters (330 feet).

•Use a straight-through cable to connect the switch to a server or workstation. For more information on cabling, see pages 23 and 24.

•To connect to another switch or hub use crossover cables, or set port 1 to MDI and use a straight-through cable.

Flow control

During times of heavy network activity the switch’s port buffers can receive too much traffic and fill up faster than the switch can send the information. In cases like this, the switch must tell the transmitting device to wait so the information in the buffer can be sent. This intervention is called flow control.

You can enable or disable flow control for each port on the Express 410T switch. By default, flow control is enabled. The method of flow control depends on whether the ports are set to full- or half- duplex. If a port is operating at half-duplex the switch sends a collision causing the transmitting device to wait. If the port operates at full-duplex, the switch sends out an 802.3x PAUSE frame.
