You can use QSFP+, SFP+, and SFP transceivers with copper or optical cables for the uplink and
downlink ports, RJ-45 connectors for the management ports, RJ-45 connector for the console port, and
a USB A connector for the USB port.
The four uplink ports support QSFP+ transceivers, each of which can be connected to a single 40-Gigabit
optical cable, a 40-Gigabit copper cable, or four 10-Gigabit copper cables with SFP+ transceivers.
