Connecting to the 10/100/1000 Ports
•
Step 1
When connecting to workstations, servers, and routers, connect a straight-through cable to an RJ-45
connector on the front panel.When connecting to routers or repeaters, use a crossover cable.
Note
You can use the mdix auto interface configuration command in the CLI to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled,
the router detects the required cable type for copper Ethernet connections and configures the interfaces
accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a
copper 10/100/1000, or an SFP module port on the router, regardless of the type of device on the other
end of the connection.
Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
when both the router and the connected device have established link.
If the port LED does not turn on, the device at the other end might not be turned on, or there might be a
cable problem or a problem with the adapter installed in the attached device.
On user network interface (UNI) ports, the port LED is green after the link is established.
Note
Reconfigure and reboot the connected device, if necessary.

Step 4
Repeat Steps 1 through 3 to connect each device.
Connecting to SFP Modules
This section describes how to connect to SFP modules. For instructions on how to connect to fiber-optic
SFP modules, see the

Connecting to Fiber-Optic SFP Modules
Follow these steps to connect a fiber-optic cable to an SFP module:
Class 1 laser product. Statement 1008
Warning
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
Caution
until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables
from contamination and ambient light.
Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
Step 1
Insert one end of the fiber-optic cable into the SFP module port.
Step 2
Insert the other cable end into a fiber-optic connector on a target device.
Step 3
Observe the port status LED.
