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.
