9 Ethernet 10/100 switched Ethernet connection redundant uplink ports.
Use either Ethernet port to connect to the LAN. If the other port is
connected, it becomes active only when the active port
experiences a link failure. The ports stay in that state even after
the failed port returns to a positive link state. Both ports show a
positive link status even though only one port at a time is active.
Typically, you would connect each port to a different switch and
subnet.

If S1 and S2 stop normal flashing and intermittently flash twice,
the mirroring process has failed.
