additional Ethernet connections. If you install optional Ethernet-compatible switch
modules in I/O bays 3 and 4, these switch modules must be identical.
The optional Ethernet switch modules contain four ports with RJ-45 connectors.
These connectors provide a 10/100/1000 Base-T interface (either at half-duplex or
full duplex) for connecting twisted-pair cable to the Ethernet network. You must
purchase and install a compatible cable to connect these devices. To connect an
Ethernet controller port to a repeater or switch module, use an unshielded twisted
pair (UTP) cable with RJ-45 connectors at both ends. For 100 Mbps or higher
operation, Category 5 cabling is required. For 10 Mbps operation, Category 3
cabling is required.
