Chapter 6: SFP+
This chapter provides installation procedures and specifications for Small Form Factor Pluggable
plus (SFP+) transceivers.
SFP+ transceivers
This section describes how to select and install Small Form Factor Pluggable plus (SFP+)
transceivers.
Use an SFP+ transceiver to connect a device motherboard to fiber optic or direct attach cables, up
to 15 meters in length. SFP+ transceivers are similar to SFP transceivers in physical appearance
but SFP+ transceivers support 10-gigabit per second (Gbps) connections. SFP+ modules do not
interoperate with SFP modules.
The Avaya VSP 8200 supports SFP+ transceivers on ports 1/1-1/40 and 2/1-2/40.
The Avaya VSP 8400 ports can be used with SFP+ transceivers depending on the type of Ethernet
Switch Modules (ESM) installed. For information on ESM types for VSP 8400, see Installing the
Avaya Virtual Services Platform 8000 Series, NN47227-300.
The Avaya VSP 7200 Series supports SFP+ transceivers on ports 1/1–1/48.
The Avaya VSP 4000 supports SFP+ transceivers on fiber ports 49 and 50.
Important:
• The VSP switches operate in strict mode for SFP+ transceivers, which means that the
switch will not bring the port up operationally when using non-Avaya SFP+ transceivers.
• The VSP switches operate in forgiving mode for SFP+ direct attach cables (DACs), which
means that the switch will bring up the port operationally when using non-Avaya direct
attach cables. Avaya does not provide support for operational issues related to these
DACs, but they will operate and the port link will come up.
Note:
Although VSP 8000 and VSP 7200 Series support 10G and 40G DAC cables in
forgiving mode, the output to the command show pluggable-optical-modules
basic displays the corresponding vendor names instead of leaving the vendor name
blank as in the releases prior to VOSS 4.2.1.
