Combo interface (only available on the 5120 EI switches)
On a 5120 EI switch, the last four 10/100/1000Base-T Ethernet ports and the four SFP ports are
copper/fiber combo ports in pairs, as shown in Table 17.
They form four combo interfaces. When one
port in a pair is activated, the other port automatically shuts down. For more information about combo
interfaces, see HP 5120 EI Switch Series Configuration Guides.
