Step 2: View the LED of the Ethernet interface. ON means a link is present. OFF means no link is
present. If the LED is OFF, check the line for the cause.
Connecting an Ethernet Optical Interface
Cables for connecting an Ethernet optical interface
For 10/100/1000 Mbps Ethernet optical interfaces, use single-mode or multi-mode optical fibers to
connect to the Ethernet based on the type of the installed 1000 Base-SX/LX SFP modules. As the
optical interfaces of these SFP modules use LC-type fiber-optic connectors, you must use fibers with
LC-type connectors for them. All these SFP modules are hot swappable.
Optical interface connection procedure
When connecting optical fibers, make sure that:
The curvature radius of fibers is no less than 10 cm (3.9 in.).
The Tx and Rx connectors are correctly connected.
The fiber ends are clean.
Laser is dangerous! To protect your eyes against radiation harm, never stare into an optical fiber
connector directly.
Step 1: Put on an ESD-preventive wrist strap and make sure that the ESD-preventive wrist strap is
properly grounded. Then take the SFP module out of the package.
Step 2: Remove the optical module filler plug from the shielding hood of the optical interfaces of the AC.
Step 3: Hold the SFP module and slide the SFP module along the optical interface shielding hood gently
until the SFP module makes skin contact with the AC.
Step 4: Distinguish between the Rx and Tx interfaces. Connect one end of an optical fiber to the Rx
interface of the AC and the other end to the Tx interface of the peer device. Use another fiber to connect
the AC and the peer device in the opposite way.
Step 5: Power on the AC and check the 1000 Mbps LED of the 10M/100M/1000M Ethernet interface.
ON means the Rx link is present. OFF means no Rx link is present. If the LED is OFF, check the line for
the cause.
Installation Verification
After installation, make sure that:
The correct power supply is used.
The ground wire is securely connected.
Both the console cable and power cord are correctly connected.
