Chapter 1: Overview

SFP+ Slots

The switches have four SFP+ slots that support the following types of SFP

1000Mbps and SFP+ 10Gbps transceivers:

 1000Base-SX/LX SFP transceivers

 Single-port BiDi 1000Base-LX SFP transceivers

 1000Base-ZX SFP transceivers

 10Gbps, 10GBase-SR/LR fiber optic transceivers

 10Gbps AT-SP10TW direct connect twinax cables with SFP+

transceiver-style connectors

You may use the transceivers to connect switches to other network

devices over large distances, build high-speed backbone networks

between network devices, or connect high-speed devices, such as

servers, to your network.

The switches support a variety of short and long distance SFP and SFP+

modules. For a list of supported SFP modules, contact your Allied Telesis

representative or visit our web site.

Note

SFP+ slots 27 and 28 on the AT-x510-28GTX and AT-x510-28GPX

Switches and slots 51 and 52 on the AT-x510-52GTX and AT-x510-

52GPX 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 74.
