3.7 Connecting the External Interface Cables
Precautions
Correctly distinguish single-mode and multi-mode fibers and ports.
Avoid bends of small curvature at the connector.
Simple Connection Steps
Step 1: Connect one end of the RJ45 connector to the Ethernet MGMT interface of the device board, and the other end
to the NMS or a control terminal.
Step 2: Insert the single-mode or multi-mode fiber into the appropriate interface according to the identification on the
panel of the line card. Distinguish the Rx/Tx end of the fiber. Step 3: Insert the twisted pair with the RJ45 port into the
appropriate interface according to the identification on the panel of the line card. Distinguish the crossover cable and
straight-through cable.
3.8 Bundling the Cables
Precautions
The power cables and other cables should be bundled in a visually pleasing way.
When you bundle fibers, make sure that the fibers at the connectors have natural bends or bends of large radius.
Do not bundle fibers and twisted pairs too tightly, as this may press the fibers and affect their service life and
transmission performance.
Simple Bundling Steps
Bind the drooping part of the fibers and twisted pairs of each board, and lead them to both sides of the chassis for
convenience.
On the both sides of the chassis, fasten the fibers and twisted pairs to the cabinet cable management ring or
cabling chute.
For the power cables, you should bundle them closely along the chassis downward in a straight line wherever possible.
3.9 Verifying Installation
Before verifying the installation, cut off the power supply to avoid any personal injury or damage to the component
due to connection errors.
Verify that the ground cable is connected.
Verify that the cables and the power cord are properly connected.
Verify that the cablings are all indoor. If any outdoor cabling is found, check the connection to lightening protection
power strip of AC power or lightening arrester of Ethernet port.
Maintain a minimum clearance of 10 cm (3.94 in.) around the chassis to facilitate heat dissipation.
