GbE Medium Module

The 10-port 10/100/1000 Ethernet Advanced L2/L3 Medium Module
provides ten autonegotiating 10/100/1000 Mbps copper Ethernet ports and
two SFP Gigabit Ethernet ports (full duplex). Up to ten ports can be in use
at one time. The module is non-blocking. The 10-port GbE Medium Module
provides both Layer 2 switching and Layer 3 routing functionality.
You can use copper port 5 or fiber port 5—you cannot use both
simultaneously (the same holds true for copper port 10 and fiber port 10). If
a copper cable and a fiber cable are connected to the same port (port 5, for
example), the module uses the first active link. If you disconnect the active
link, the module automatically switches to the remaining connection.
The following figure shows the 10-port GbE Medium Module.
