Built-in Gigabit Ethernet Ports
Four built-in 10/100/1000 Gigabit Ethernet ports provide LAN connections to hubs, 
switches, local servers, and workstations. You can also designate an Ethernet port 
for management traffic.
When configuring one of these ports, you reference the interface name that 
corresponds to the location of the port. From left to right on the front panel, the 
interface names for the ports are ethernet0/0 through ethernet0/3.
Each port has two LEDs located on the top of the port. Figure 3 displays the location 
of the LEDs on each Ethernet port, and Table 3 shows the name, function, color, 
state, and description of the Ethernet port LEDs.
