Chapter 3: Overview of the AT-SBx31CFC960 Controller Fabric Card
SFP+ Slots
72
The four SFP+ slots on the front panel of the controller card can support
1000Mbps SFP or 10Gbps SFP+ transceivers. The slots can be used to
add high speed uplink ports to the chassis. A list of supported transceivers
is available from the Allied Telesis web site.
The SFP+ slots operate independently of the active or inactive state of a
controller card and as such forward traffic even when a controller card is
the inactive master card in a chassis with two controller cards.
Consequently, a chassis with two controller cards has eight active SFP+
slots.
Each SFP+ slot has one LED. The states of the LED are described in
Table 21.
