Combo interface 
•  On the A5500-24G-SFP EI (2 slots) and A5500-24G-SFP EI TAA (2 slots) switch, the last eight SFP 
ports and the eight 10/100/1000Base-T Ethernet po rts are copper/fiber combo ports in pairs, as 
shown in  Table 14. T
hey form eight combo interfaces.  
•   On all the other A5500 EI and A5500 SI switches, the last four 10/100/1000Base-T Ethernet 
ports and the four SFP ports are copper/fi ber combo ports in pairs, as shown in Table 14. T
 hey 
form four combo interfaces 
When one port in a pair is activated, the other po rt automatically shuts down. For more information 
about combo interfaces, see  HP A5500 EI & A5500 SI Switch Series Configuration Guides .
