Connection Guidelines
General
• The copper ports of the 410 switches are 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 410F's two fiber ports always operate at 100Mbps.
• The 410 switches are capable of autonegotiating port duplex and can
operate at half- or full-duplex.
• Configure the network so devices that talk primarily to each other 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 (328 feet).
• Use a straight-through cable to connect the switch to a server or
workstation. For more information on cabling, see "Cabling Devices."
• To connect to another switch or hub use crossover cables, or set port 1
to MDI and use a straight-through cable.
• To connect a device to one of the fiber ports, use 62.5/125 µm
multimode cabling. This cabling can be a maximum of 2,000m when
operating at full-duplex, and 160m (to a hub) or 400m (to a router,
switch, or PC) when operating at half-duplex.
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.
The Flow Control field displays the flow control status when you manually
set port speed and duplex. Whether or not flow control is enabled depends
on the duplex mode. In half-duplex mode, flow control is enabled. In full-
duplex mode, flow control is disabled.
