Power Supplies
There are five power supply models for the x930 Series switches. The
models are listed here:
AT-PWR150
AT-PWR250
AT-PWR250-80
AT-PWR800
AT-PWR1200
The top three models are primarily intended for the non-PoE AT-x930-
28GTX, AT-x930-28GSTX, and AT-x930-52GTX Switches. The bottom
two power supplies are for the PoE AT-x930-28GPX and AT-x930-52GPX
Switches.
Figure 5 illustrates the AT-PWR150 and AT-PWR250 Power Supplies.
The two power supplies are functionally identical.
Figure 5. AT-PWR150 and AT-PWR250 Power Supplies
The two power supplies are primarily designed for the non-PoE switches
and have these operating characteristics:
The power supplies provide system power, but no PoE power.
A single power supply can power an entire non-PoE switch.
Installing two power supplies in a switch adds power redundancy.
The power supplies are not recommended for the PoE AT-x930-
28GPX and AT-x930-52GPX Switches because they do not have
power for PoE devices. You may install them into PoE switches,
but the switches will not be able to support PoE powered devices.
Chapter 1: Overview
26
The AT-PWR250-80 DC Power Supply illustrated in Figure 6 has the
same operating characteristics as the AT-PWR150 and AT-PWR250
Power Supplies. It, too, is intended for the non-PoE switches because it
can supply system power, but no PoE power. The only difference is that
this power supply has a DC wiring connector instead of an AC connector,
for DC wiring environments.
Figure 6. AT-PWR250-80 Power Supply
Figure 7 illustrates the AT-PWR800 Power Supply.This power supply is
primarily intended for the PoE AT-x930-28GPX and AT-x930-52GPX
Switches. It provides both system power to the switch as well as up to 380
watts of PoE power for the powered devices connected to the network
ports.
Figure 7. AT-PWR800 Power Supply
A PoE switch with one AT-PWR800 Power Supply has the following power
characteristics:
Full system power
380 watts of PoE power
A switch with two AT-PWR800 Power Supplies has these power
characteristics:
Full system power and redundant system power
Either 740 watts of PoE power or 380 watts of active PoE power
and 380 watts of redundant PoE power.
You may install the AT-PWR800 Power Supply in the non-PoE AT-x930-
28GTX and AT-x930-52GTX Switches. But because the switches do not
support PoE, the power supply will provide system power but no PoE
power.
x930 Series Installation Guide for Stand-alone Switches
27
The AT-PWR1200 Power Supply is shown in Figure 8. It is similar to the
AT-PWR800 Power Supply in that it is intended for the PoE AT-x930-
28GPX and AT-x930-52GPX Switches because it provides both system
power and power for PoE devices. The difference between them is the
amount of PoE power. The AT-PWR1200 Power Supply can provide up to
740 watts compared to 380 watts for the AT-PWR800 Power Supply.
Figure 8. AT-PWR1200 Power Supply
A PoE switch with one AT-PWR1200 Power Supply has the following
power characteristics:
Full system power
740 watts of power for PoE devices
A switch with two AT-PWR1200 Power Supplies has these power
characteristics:
Full system power and redundant system power
Either 1440 watts of PoE power or 740 watts of active PoE power
and 740 watts of redundant PoE power.
Guidelines Please review the following guidelines concerning power supplies:
The x930 Series Switches do not come with power supplies. The
power supplies must be ordered separately.
If you install two power supplies in the switch, they must both be
the same model. For example, you may install two AT-PWR800
Power Supplies or two AT-PWR1200 Power Supplies in a switch.
You may not install two different power supply models in the
switch.
The non-PoE AT-x930-28GTX AT-x930-28GSTX, and AT-x930-
52GTX Switches require only one power supply for full operations.
Installing a second power supply adds power redundancy, which
protects against interruptions to network operations in the event
one power supply loses power or fails. Power redundancy is
available only when both AC or DC connectors on the switch are
connected to power sources.
Chapter 1: Overview
28
The PoE AT-x930-28GPX and AT-x930-52GPX Switches also
require only one power supply for network operations, excluding
PoE. The switches can continue to operate even if one power
supply fails or loses power.
The second power supply in the PoE switches either increases the
amount of power for PoE or adds PoE redundancy. For further
information, refer to “Power Budget” on page 33.
The DC wires for the AT-PWR250-80 DC Power Supply should be
routed from a DC load center containing appropriate overcurrent
branch protection for each DC feed, as required by the cognizant
local electrical authority.
Refer to “Technical Specifications” on page 149 for the input voltage
ranges.
Warning
Power cord is used as a disconnection device. To de-energize
equipment, disconnect the power cord. E3
Warning
This unit might have more than one power cord. To reduce the risk
of electric shock, disconnect all power cords before servicing the
unit. E30
Note
The AT-PWR150, AT-PWR250, AT-PWR800, and AT-PWR1200
Power Supplies are powered on or off by connecting or
disconnecting the power cords. The AT-PWR250-80 Power Supply
is powered on or off with its On/Off power switch or by deactivating
the DC circuit.

10/100/1000Base-T Twisted Pair Ports
The twisted pair ports on the switches are described in this section.
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set
manually using the management software or automatically with Auto-
Negotiation (IEEE 802.3u), the default setting.
Note
The ports must be set to Auto-Negotiation to function at 1000 Mbps
and are not compatible with devices that are not IEEE 802.3u
compliant.
Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The
duplex mode of a port, like port speed, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE
802.3u), the default setting.
The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through Auto-
Negotiation.
Note
A switch port should not use Auto-Negotiation to set its duplex mode
if it is connected to a network device that does not support Auto-
Negotiation for 10 or 100 Mbps operation and has a fixed duplex
mode of full-duplex. Otherwise, a duplex-mode mismatch may occur
in which a switch port and a network device operate at different
duplex modes. The duplex modes of switch ports that are connected
to network devices that do not support Auto-Negotiation should be
set manually through the management software.
Wiring
Configuration
The wiring configuration of a port operating at 10 or 100 Mbps can be MDI
or MDI-X. The wiring configurations of a switch port and a network device
connected with straight-through twisted pair cabling have to be opposite,
such that one device is using MDI and the other MDI-X. For instance, a
switch port has to be set to MDI-X if it is connected to a network device set
to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab-
compliant). This feature enables the switch to automatically negotiate with
network devices to establish their proper settings.
Chapter 1: Overview
30
The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.
Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
Cable
Requirements
The cable requirements of the ports are given in Table 2.
Note
For the cable requirements for the ports on the AT-x930-28GPX and
AT-x930-52GPX Switches for PoE devices, refer to Table 4 on
page 32.
Port Pinouts Refer to Table 29 on page 156 and Table 30 on page 156 for the port
pinouts of the 10/100/1000Base-T twisted pair ports.
