3.1.1
SFP+ Interfaces
The SFP+ interfaces will support 10Gbps SFPs that meet SFF-8431 MSA.
Only
10Gbps transceivers are supported in
V2.1
Embedded Software
The list of verified SFPs is available on the Axtrinet website:
www.axtrinet.com/transceivers.html
The SFP+ interfaces will also support certain 10GBase-T transceivers that exceed the SFF-8431
power budget of 1W, but only in the upper ports (1,3,5,7) due to thermal limitations.
10GBase-T transceivers are disabled in the lower ports (2,4,6,8)
3.1.2
QSFP+ Interfaces
The QSFP+ interfaces will support 40Gbps QSFPs that meet SFF-8436 MSA.
The list of verified QSFPs is available on the Axtrinet website:
www.axtrinet.com/transceivers.html
The QSFP+ interfaces can be configured in 40Gbps mode (default) or 4X10Gbps mode, where
each of the 10Gbps lanes that comprise the 40Gbps link are managed independently (Section
5.3). Switching between 40Gbps and 4x10Gbps modes is performed in the Port Control
Window (Section 6.8.1).

LEDs
Some APG units are fitted with SFP Cages with four LEDs per vertical port pair.
In all cases, only the outer LEDs are used. The inner two LEDs are not used.
