The XEM2-8XSTm Card also has four transceiver ports that support the
following types of 1Gbps SFP transceivers, 10Gbps SFP+ transceivers,
and 10Gbps direct connect cables:

1Gbps SX or LX SFP fiber optic transceivers

10Gbps SR or LR SFP+ fiber optic transceivers

10Gbps one meter SP10TW1, three meter SP10TW3, and seven
meter SP10TW7 direct connect twinax cables, with SFP+
transceiver-style connectors
Guidelines about the SFP+ transceiver ports are listed here:
 The ports do not support 100Mbps transceivers.

The ports support full-duplex mode only.

You can set the port speeds with Auto-Negotiation or manually.
The default is Auto-Negotiation.
SFP and SFP+ transceivers are purchased separately. For a list of
supported transceivers, refer to the SBx908 GEN2 Series data sheet on
the Allied Telesis web site.
The ports have link and activity LEDs. The states of the LEDs are

The transceiver has established a 1GBase
link to a network device.
The transceiver is transmitting or receiving
data at 1GBase.
Possible causes of this state are listed
