Whether you are using an auxiliary power (USB) cable to draw additional power beyond what is
provided by the host switch.
Note
•
The figures listed assume that, in every case, both adapter ports are connected to the host
switch. The adapter will not operate properly if only one port is connected to the host
switch.
•
Unless noted otherwise, all switch models listed have SFP+ ports that can be configured
for 10Gb. For some X440-G2 models, a license upgrade is required for 10 Gb functionality.
•
For X460-G2 switches, connecting the LRM/MACsec Adapter to SFP+ ports on the VIM-2x
module is not supported.
