Ports 1 to 24 on the AT-x950-28XSQ Switch support 1Gbps SFP or
10Gbps SFP+ transceivers.
The ports support the following types of transceivers:

1Gbps SX/EX/LX SFP transceivers

10Gbps SR/LR/ER/ZR SFP+ fiber optic transceivers

1/10Gbps SP10T transceiver with RJ-45 connector

10Gbps SP10TW1, SP10TW3, and SP10TW7 direct attach twinax
cables with SFP+ transceiver-style connectors, in lengths of one,
three, and seven meters, respectively
Here are the guidelines:
 The ports do not support 100Mbps-FX transceivers.
 They support full-duplex mode only.
 You can set the port speeds with Auto-Negotiation or manually.
The default is Auto-Negotiation.
Transceivers must be purchased separately. For a list of supported
transceivers, refer to the product data sheet on the Allied Telesis web site.
The LEDs are located between the ports. Each port has one LED. Refer to
