10/100/1000Base-T Twisted Pair Ports
The switches have 24 or 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.
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.
Wiring
Configuration
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.
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 802.3abcompliant). This feature enables the switch to automatically negotiate with
network devices to establish their proper settings.
23

The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.

Power Over Ethernet
The AT-x510-28GPX and AT-x510-52GPX 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 and AT-x51052GPX 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 and AT-x510-52GPX 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 26. The classes are based on the amount of power the devices
require. The switches support all five classes.

Power Budget The AT-x510-28GPX and AT-x510-52GPX Switches have a power budget
of 370 watts. This is the maximum amount of power the switches can
provide at one time to the powered devices.
The AT-x510-28GPX and AT-x510-52GPX Switches have two power
supplies. Each power supply is responsible for providing 185 watts, or half,
of the power budget. Both power supplies must be connected to AC power
sources for the switch to provide the full 370 watts. The power budget is
reduced to 185 watts if only one power supply is connected to a power
source.
The power requirements of the PoE devices determine the maximum
number of devices the switch can support at one time. So long as the total
power requirements of the powered devices is less than the power budget
of the switch, the switch can supply power to all the devices. But if the total
power requirements exceed the power budget, the switch denies power to
one or more ports using a mechanism referred to as port prioritization.
To determine whether the power requirements of the PoE devices you
plan to connect to the switch exceed its power budget, refer to their
documentation for their power requirements and add the requirements
together. The switch should be able to power all of the devices
