Small Form Factor Pluggable (SFP)
Transceivers
AT-9900 Series switches have 1000BASE-X Small Form Factor Pluggable (SFP)
uplink sockets on their front panel. The AT-9924T/4SP and AT-9924T have four
SFP sockets and the AT-9924SP has 24 SFP sockets.
Certain fibre and copper SFP transceivers are supported. This allows you to
interchange port types to meet changing network requirements. SFP
transceivers are hot swappable.
Approved SFP transceivers
A range of SFP transceivers have been tested and approved for use with the
AT-9900 Series Switches. You can purchase SFP transceivers when you

switches:
■ AT-MG8T 100m Base-T SFP

SFP port operation
How a Small Form Factor Pluggable (SFP) port operates depends on the type of
SFP transceiver installed in the port.
For a SFP port with an approved fibre SFP transceiver installed, the speed and
duplex setting is fixed at 1000Mbps full duplex autonegotiation.
For a SFP port with an approved copper SFP transceiver installed, the available
speed and duplex settings are:
■ 10Mbps and 100Mbps half duplex
■ 10Mbps and 100Mbps half duplex autonegotiation
■ 10Mbps and 100Mbps full duplex
■ 10Mbps and 100Mbps full duplex autonegotiation
■ 1000Mbps full duplex autonegotiation
An error message is displayed if a SFP port cannot operate at the specified
speed or duplex mode.
