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 27.
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 35.
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
Chapter 2, “Virtual Chassis Stacking” on page 55.
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 40.
