Installation Instructions

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, 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.
• Avaya recommends the use of Avaya branded SFP and SFP+ transceivers as they have
been through extensive qualification and testing. Avaya will not be responsible for issues
related to non-Avaya branded SFP and SFP+ transceivers.
SFP+ labels
The typical Avaya SFP+ transceiver has a label on the top and bottom or side of the transceiver.
The following figures show example labels. Avaya does use alternate labels, depending on the size
of the device and space available for label information. Some devices do not have a CLEI code or
label.
