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 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 them
with standard SFP or SFP+ transceivers. The configuration
instructions are provided later in this guide, in “Powering On the
Switches Simultaneously” on page 93.
