10/100Base-TX Twisted Pair Ports
Basic Features
Speed
Duplex Mode
The IA series switch has 8 10/100Base-TX ports.
Here are the basic features of the 10/100 Mbps twisted pair ports:
10Base-T and 100Base-TX compliant
IEEE 802.3u Auto-Negotiation compliant
Auto-MDI/MDIX
100 meters (328 feet) maximum operating distance
IEEE 802.3x flow control in 10/100Base-TX full-duplex operation
Support for jumbo frames up to 10KB
Support for store-and-forward switching
RJ-45 connectors
The ports can operate at either 10 or 100 Mbps. On the AT-IA708C switch,
the speeds are fixed to Auto-Negotiation. On the AT-IA810M switch, the
speeds can be set manually using the management software or
automatically with Auto-Negotiation (IEEE 802.3u). The default setting is
Auto-Negotiation.
The twisted pair ports can operate in either half- or full-duplex mode. The
duplex mode determines the manner in which a port transmits data. A port
set to half-duplex can either transmit or receive data at one time, while a
port operating in full-duplex can transmit and receive data at the same
time. The best network performance is achieved with the full-duplex
setting, but not all network equipment is designed to support that duplex
mode.
On the AT-IA708C switch, the duplex modes are fixed to Auto-Negotiation.
On the AT-IA810M switch, the duplex modes, like port speeds, can be set
manually using the management software or automatically with Auto-
Negotiation (IEEE 802.3u). The default setting is Auto-Negotiation.
The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through Auto-
Negotiation.
