Connect to SFP Modules
This section describes how to connect to SFP modules.
Connect Fiber Optic SFP Modules
Do not remove the rubber plugs from the SFP module port or from the fiber optic cable until you are ready
to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and
ambient light.
Caution
Step 1 Remove the rubber plugs from the module port and fiber optic cable, and store them for future use.
Step 2 Insert one end of the fiber optic cable into the SFP module port.
Step 3 Insert the other end into a fiber optic connector at a target device.
Step 4 Observe the port's LED status.
The LED turns green when the device and the target device establish a link.
If the LED is off, check whether the target device is turned on, or whether there is any failure in the target device.
Step 5 If necessary, reconfigure and restart the device or target device.
Install the Chassis Ground Connection
Before you connect the power or turn on the power to the router, you must provide an adequate chassis ground
(earth) connection to your router.
This section describes how to ground the router chassis. The grounding lug location is on the back panel of
the router.
Ensure that the grounding lug wire does not cover the fan opening.
