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
An LSP4G4T6P interface module provides six SFP ports. You can install GE SFP transceiver
modules in
Table4-3 and GE SFP cables in Table4-4 in the SFP ports.
SFP+ port
The following switches provide fixed SFP+ ports on the front panel:
•
S6520X-16ST-SI
•
S6520X-24ST-SI
•
S6520X-18C-SI
•
S6520X-10XT-SI
•
S6520X-16XT-SI
•
S6520X-26C-SI
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 in
Table4-3 , GE SFP cables in Table4-4 ,10-GE SFP+ transceiver modules in
Table4-5 , and 10-GE SFP+ cables in 0 in the SFP+ ports.
