SFP Slots Here are the basic features of the SFP slots on the AT-x510-28GSX and
AT-x510-28GSX-80 Switches:
Supports 100Base-FX and 1000Base-SX/LX SFP transceivers
Supports single-port BiDi 1000Base-LX SFP transceivers
Supports 1000Base-ZX SFP transceivers
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:

Chapter 1: Overview
Note
SFP+ slots 27 and 28 on the 28-port switches and slots 51 and 52
on the 52-port switches are initially configured as stacking slots for
the VCStack feature. If you intend to use the switch as a stand-alone
unit, you must disable the VCStack feature before you can use the
slots with standard SFP or SFP+ transceivers. The configuration
instructions are provided later in this guide, in “Configuring the
Switch for Stand-alone Operations” on page 93.
Stacking Slots Two of the SFP+ slots can be used to create a VCStack of up to four
switches. The slots support these stacking transceivers when the switch is
in the stacking mode:
AT-StackXS/1.0 Twisted Pair Transceiver - 1 meter
AT-StackOP/0.3 Fiber Optic Transceiver - 300 meters
AT-StackOP/9.0 Fiber Optic Transceiver - 9 kilometers

Power Supplies The AT-x510-28GTX, AT-x510-28GPX, AT-x510-28GSX,
AT-x510-52GTX, and AT-x510-52GPX Switches have two pre-installed
AC power supplies. The AT-x510L-28GP, AT-x510L-28GT,
AT-x510L-52GP, and AT-x510L-52GT Switches have one pre-installed AC
power supply. The AT-x510-28GSX-80 Switch has two pre-installed DC
power supplies. The DC power supply option is only available in the
AT-x510-28GSX-80 Switch. The power supplies are not field-replaceable.

10/100/1000Base-T Twisted Pair Ports
Note
Note
The AT-x510-28GTX, AT-x510-28GPX, AT-x510L-28GT, and
AT-x510L-28GP Switches have 24 10/100/1000Base-T ports. The
AT-x510-52GTX, AT-x510-52GPX, AT-x510L-52GT, and AT-x510L-52GP
Switches have 48 10/100/1000Base-T ports.
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set
manually using the management software or automatically with AutoNegotiation (IEEE 802.3u), the default setting.
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.
x510 Series Installation Guide for Stand-alone Switches
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 AutoNegotiation.
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 AutoNegotiation 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.
27
Chapter 1: Overview
Note
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3abcompliant). This feature enables the switch to automatically negotiate with
network devices to establish their proper settings.
The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.

The ports have a maximum operating distance of 100 meters (328 feet).

Power Over Ethernet
The AT-x510-28GPX, AT-x510L-28GP, AT-x510-52GPX, and
AT-x510L-52GP Switches feature Power over Ethernet (PoE) on the 10/
100/1000Base-T ports. PoE is used to supply power to network devices
over the same twisted pair cables that carry the network traffic.
The main advantage of PoE is that it can make it easier to install a
network. The selection of a location for a network device is often limited by
whether there is a power source nearby. This often limits equipment
placement or requires the added time and cost of having additional
electrical sources installed. But with PoE, you can install PoE-compatible
devices wherever they are needed without having to worry about whether
there are power sources nearby.
A device that provides PoE to other network devices is referred to as
power sourcing equipment (PSE). The AT-x510-28GPX, AT-x510L-28GP,
AT-x510-52GPX, and AT-x510L-52GP Switches act as PSE units by
adding DC power to the network cable, thus functioning as a central power
source for other network devices.
x510 Series Installation Guide for Stand-alone Switches
Devices that receive their power from a PSE are called powered devices
(PD). Examples include wireless access points, IP telephones, webcams,
and even other Ethernet switches.
The switch automatically determines whether or not a device connected to
a port is a powered device. Ports that are connected to network nodes that
are not powered devices (that is, devices that receive their power from
another power source) function as regular Ethernet ports, without PoE.
The PoE feature remains activated on the ports, but no power is delivered
to the devices.
PoE Standards The AT-x510-28GPX, AT-x510L-28GP, AT-x510-52GPX, and
AT-x510L-52GP Switches support these PoE standards:
PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the
switch port to support powered devices that require up to 12.95
watts.
PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at
the switch port to support powered devices that require up to 25.5
watts.
Powered Device
Classes
Powered devices are grouped into the five classes listed in Table 2 on
page 30. The classes are based on the amount of power the devices
require. The switches support all five classes.
