From the data sheet, the MCS7816 has dual-port Gigabit Ethernet controller embedded. So I am wondering, can both Gigabit Ethernet port be used (to do a Network Teaming) for redundancy purpose.
NIC Teaming Support
Server platforms with dual Ethernet network interface cards (NICs) can support NIC teaming for network fault tolerance with Cisco Unified Communications Manager. Cisco began support of NIC teaming on HP servers in the 5.0(1) release and began support on IBM servers in the 6.1(2) release. This feature allows a server to be connected to the Ethernet via two NICs and, hence, two cables. NIC teaming prevents network downtime by transferring the workload from the failed port to the working port. NIC teaming cannot be used for load balancing or increasing the interface speed.
Hope this helps!
