Models
Table 1 lists the models and basic features of the x930 Series of stackable
Gigabit Layer 3 switches.
Additional information is listed here:
The switches do not come with power supplies. The power
supplies must be ordered separately. For more information, refer
to “Power Supplies” on page 25.
The power budgets of the AT-x930-28GPX and AT-x930-52GPX
Switches for PoE+ powered devices depend on the number and
types of power supplies installed in theunits. For more information,
refer to “Power Budget” on page 33.
You may use the VCStack feature to stack the switches with either
the S1 and S2 ports, which come standard with the units, or with
the optional AT-StackQS card. For more information, refer to the
x930 Series Installation Guide for Virtual Chassis Stacking.
The twisted pair ports and SFP slots on AT-x930-28GSTX Switch
are paired together. Only one port or slot in a pair is operational at
a time. For more information, refer to “SFP Slots” on page 37.

Supports single-port BiDi 100Base-FX and 1000Base-LX SFP
transceivers
Supports 1000Base-ZX SFP transceivers
Note
The SFP slots and twisted pair ports on the AT-x930-28GSTX
Switch are paired together. Only one slot or port in a pair is active at
a time. For more information, refer to “SFP Slots” on page 37.
Note
SFP transceivers must be purchased separately. For a list of
supported transceivers, contact your Allied Telesis distributor or
reseller.
SFP+ Slots Here are the basic features of the four SFP+ slots on the switches:
Supports 10Gbps, 10GBase-SR/LR fiber optic transceivers

SFP+ transceiver-style connectors
Supports 1000Base-SX/LX SFP transceivers
Supports single-port BiDi 1000Base-LX SFP transceivers
Supports 1000Base-ZX SFP transceivers
Note
The SFP+ slots do not support 100Mbps 100Base-FX transceivers.
Note
The slots support full-duplex mode only. They do not support half-
duplex mode.
Note
SFP and SFP+ transceivers must be purchased separately. For a
list of supported transceivers, contact your Allied Telesis distributor
or reseller.

Note
SFP+ slots 27/S1 and 28/S2 on the 28-port switches and slots 51/S1
and 52/S2 on the 52-port switches are initially configured as stacking
slots for the VCStack feature. If you plan to use the switch as a
stand-alone unit, you may disable the VCStack feature and use the
