EOTec 2104 User Manual
Introducing Switch Tools
necessary, you can manually configure the settings for a port to a fixed, predetermined
state (or a restricted set of the possible modes).
The Port Configuration Interface
Admin
Ports can be enabled or disabled in the Weed Ring Switch. Ports that are disabled are
virtually nonexistent (not visible in terms of switch operation). Choose to enable or
disable a port by selecting
Enabled
or
Disabled
, respectively.
Negotiation
All copper ports in the Weed Ring Switch are capable of auto-negotiation such that the
fastest bandwidth is selected. By default, all ports in the Weed Ring Switch are set to
auto-negotiate. It is recommended that the ports be left in the
Auto
setting to reduce
setup time. If the attached device does not support auto-negotiation, choose
Fixed
.
All fiber ports in the Weed Ring Switch support 100 Mbps with full duplex only, and
therefore need no configuration.
Speed/Duplex/Flow Control
The Weed Ring Switch accepts several local area network Ethernet standards. The first
standard, 10BaseT, runs 10 Mbps with twisted-pair Ethernet cable between network
interfaces. The second local area network standard is 100BaseTX, which runs at
100 Mbps over the same twisted-pair Ethernet cable. (Note that Category 5 or better
cable is required for 100BaseTX.) The standard for fiber is 100BaseFX, which runs at
100 Mbps.
The following options are available:
10h
10 Mbps, Half Duplex
10f
10 Mbps, Full Duplex
100h
100 Mbps, Half Duplex
100f
100 Mbps, Full Duplex
FC
Flow control can also be enabled or disabled. Devices use flow control to
ensure that the receiving device takes in all the data without error. If the
transmitting device sends data at a faster rate than the receiving device can
accept, the receiving device
’
s buffer will eventually fill up with pending data.
No further data can be accepted when the buffer is full, so a flow control
signal is sent to the transmitting device to temporarily stop the flow of
incoming data.
