AT-2450FTX and AT-2451FTX Series
The adapters in the AT-2450FTX Series are:
ˆ AT-2450FTX/SC
ˆ AT-2450FTX/ST
The adapters in the AT-2451FTX Series are:
ˆ AT-2451FTX/SC
ˆ AT-2451FTX/ST
These are dual port adapters. They feature a twisted pair port and a fiber
optic port. The twisted pair port has a standard RJ-45 connector and
operates at either 10 or 100 Mbps (10Base-T/100Base-TX), half- or full-
duplex mode. The adapter features Auto-Negotiation, which allows the
network adapter port to automatically set its speed and duplex mode to
match the settings of the port on the remote device, such as an Ethernet
switch or hub.
The second port is a fiber optic port with either a duplex SC or duplex ST
connector, depending on the model. This port has a fixed operating speed
of 10 Mbps (10Base-FL), half- or full-duplex mode. The default setting is
full-duplex. The duplex mode must be set manually.
Note
You can use only one port on this adapter at a time. Do not attach
both ports to the network at the same time.
Differences between the two series are:
ˆ The AT-2450FTX Series is PCI 2.1-compliant.
ˆ The AT-2451FTX Series is PCI 2.2-compliant.

profile system. The adapter comes with two brackets, one for a
standard system and another for a low profile system.
