Installation Instructions

• The VSP switches operate in forgiving mode for SFP+ direct attach cables (DAC) when
using third party DACs. Extreme Networks 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 Series and VSP 7200 Series support 10 Gigabit and 40 Gigabit
DAC cables in forgiving mode, in releases earlier than VOSS 4.2.1, the command
output for show pluggable-optical-modules basic displays the corresponding
vendor name rather than leaving the vendor name field blank.
• Extreme Networks recommends using the SFP+ transceivers documented in this
document as they have been through extensive qualification and testing. Extreme
Networks is not responsible for issues related to third party SFP+ transceivers.
SFP+ labels
The typical SFP+ transceiver has a label on the top and bottom or side of the transceiver. The
following figures show example labels. Sometimes alternate labels are used depending on the size
of the device and space available for label information. Some devices do not have a label.
