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 38.

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
slots with standard SFP or SFP+ transceivers. The configuration
instructions are provided later in this guide, in Chapter 9,
“Configuring the Switch for Stand-alone Operation” on page 111.
S1 and S2
Stacking Slots SFP+ slots 27/S1 and 28/S2 on the 28-port switches and slots 51/S1 and
52/S2 on the 52-port switches can be used with the VCStack feature to
build a stack of up to eight switches. For instructions on the VCStack
feature, refer to the x930 Series Installation Guide for Virtual Chassis
Stacking.
