USB port
The switch has one OHC-compliant USB2.0 port that can upload and download data at a rate up to
480 Mbps. You can use this USB port to access the file system on the flash of the switch, for example,
to upload or download application and configuration files.
NOTE:
USB devices from different vendors vary in compatibilities and drivers. H3C does not guarantee the
correct operation of USB devices from all vendors on the switch. If a USB device fails to operate on
the switch, replace it with one from another vendor.
SFP+ port
The switch provides fixed SFP+ ports on the front panel. The LSWM2SP2PB, LSWM2SP4PB,
LSWM4SP8PM, and LSWM2SP8P interface modules also provide SFP+ ports. To connect peer
SFP+ ports over a long distance, use SFP/SFP+ transceiver modules and fibers. To connect peer
SFP+ ports over a short distance, use SFP/SFP+ cables. You can install GE SFP transceiver
modules and cables in
