Note
A switch port that is connected to a network device that does not
support Auto-Negotiation and has a fixed duplex mode of full-duplex
should not set its duplex mode with Auto-Negotiation. A duplex-
mode mismatch in which a switch port and a network device operate
at different duplex modes, may occur. The duplex modes of switch
ports that are connected to network devices that do not support
Auto-Negotiation should be set manually through the management
software.
The wiring configuration of a port can be MDI or MDI-X. The wiring
configurations of a switch port and a network device connected with
straight-through twisted pair cabling have to be opposite, such that one
device is using MDI and the other MDI-X. For instance, a switch port has
to be set to MDI-X if it is connected to a network device set to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab-
compliant). This feature enables the switch to negotiate with network
devices to establish the proper settings, so that the ports on the devices
are using different wiring configurations.
You can specify the wiring configuration on ports on AT-IA810M switch
from the management software. For the AT-IA708C switch, you can use
the dip switch on the front panel.
Wiring Configuration for the AT-IA708C Switch
Using the FORCE MDI dip switch, you can configure the ports on the AT-
IA708C switch with auto-MDI/MDI-X or MDI. Because the switch has only
one FORCE MDI dip switch, the setting applies all the ports on the switch.
Wiring Configuration for the AT-IA810M Switch
You may specify the wiring configuration auto-MDI/MDI-X, MDI, or MDI-X
from the management software. You can set the ports on the switch
individually.
The ports have a maximum operating distance of 100 meters (328 feet).
