1-2 Switch Description
The AT-9724TS has 24 1000T Gigabit ports that may be used in uplinking various network devices to the Switch, including PCs, hubs and other switches to
provide a gigabit Ethernet uplink in full-duplex mode.
In addition, the AT-9724TS is equipped with 4 SFP (Small Form Factor Portable) combo ports, which are to be used with fibre-optical transceiver cabling in order
to uplink various other networking devices for a gigabit link that may span great distances.These 4 SFP ports support full-duplex transmissions, have auto-
negotiation and can be used with AT-MG8LX10 (1000LX),AT-MG8SX (1000SX) and AT-MG8ZX (1000ZX) transceivers.These four ports are referred to as
“combo” ports which means that both the SFP ports and the 1000T ports are numbered the same (21–24) and cannot be used simultaneously.Attempting to use
the ports simultaneously will cause a link down status for the 1000T ports. SFP ports will always have priority over these 1000T ports.
Also included at the rear of the Switch are two 10-gigabit stacking ports used to stack up to twelve switches in a ring topology.The AT-9724TS may be used as
the master unit of a switch stack when utilizing these ports and, in total, may provide a stacking solution of up to 288 gigabit ports.
Note: The four SFP combo ports on the Switch, numbered 21–24 cannot be used simultaneously with the corresponding 1000T ports, numbered
21–24. If both ports are in use at the same time (ex. port 21 of the SFP and port 21 of the 1000T), the SFP ports will take priority over the combo
ports and render the 1000T ports inoperable.

•
High performance switching engine performs forwarding and filtering at full wire speed up to 128Gbps.
• Full- and half-duplex for all gigabit ports. Full duplex allows the switch port to simultaneously transmit and receive data. It only works with
connections to full-duplex-ca
pable end stations and s
witches.
Connections to a hub m
ust take place at half-duplex.
