The 6-port SAR-M Ethernet module has six Ethernet ports:
two SFP Fast Ethernet ports (10/100 Mb/s) (ports 1 and 2)
two XOR (combination) SFP/RJ point five Gigabit Ethernet ports (10/100/1000 Mb/s) (ports 3a/3b and 4a/4b)
two PoE-capable RJ point five copper Gigabit Ethernet ports (10/100/1000 Mb/s) (ports 5 and 6)
Ports 5 and 6 can each support Power over Ethernet (PoE). Port 5 can also support PoE+, but if it is configured for PoE+, then port 6 cannot support PoE power.
Any functionality supported on the 7705 SAR-M Ethernet ports is also supported on the 6-port SAR-M Ethernet module, with the exception of half-duplex mode (all ports) and hybrid mode (Fast Ethernet ports only).
