 NOTE:
To guarantee the functionality of the SFP+ ports, use only NEC SFP or SFP+ transceiver modules.

The SFP and SFP+ transceiver modules available for this switch series are subject to change over time.

For the most up-to-date list of SFP transceiver modules, consult your NEC sales representative or technical
support engineer.
A 40G QSFP+/10G*4 SFP+ Copper cable can mount only the SFP+ connector side to SFP+ port.

Caution:
In case of a port with 1000BASE-T-SFP, it takes about 1 second for link down measure. If your system requires
a fast linkdown detection of a physical port, NEC recommends using of the 10/100/1000BASE-T port or an
optical module.
