AT-XEM2-12XS Line Card
The AT-XEM2-12XS Card has twelve transceiver slots that support the
following types of 1Gbps SFP or 10Gbps SFP+ transceivers:
1Gbps SX or LX SFP transceivers
10Gbps SR or LR fiber optic transceivers
10Gbps AT-SP10TW direct connect twinax cables with SFP+
transceiver-style connectors
Guidelines about the SFP+ transceiver slots are listed here:
The card does not support 100Mbps transceivers.
The card supports full-duplex mode only.
You can set the port speeds with Auto-Negotiation or manually.
The default is Auto-Negotiation.
SFP or SFP+ transceivers must be purchased separately. For a list of
supported transceivers, refer to the AT-SBx908 GEN2 Series data sheet
on the Allied Telesis web site.
The slots have link and activity LEDs. The states of the LEDs are
described in Table 3.
