10/100/1000Base-T Twisted Pair Ports

Speed

Duplex Mode

Wiring

Configuration

The switches have 24 or 48 10/100/1000Base-T ports.

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.

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.

The twisted pair ports can operate in either halfor 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.

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 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.

Chapter 1: Overview

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

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

x510 Series Installation Guide for Stand-alone Switches

Power Over Ethernet

PoE Standards

Powered Device

Classes

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-x510- 52GPX Switches act as PSE units by adding DC power to the network cable, thus functioning as a central power source for other network devices.

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.

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 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
