3.5 Connecting the External Cables
Precautions
Correctly distinguish single-mode and multi-mode fibers and ports.
Avoid bends of small radius at the connector.
Steps
Step 1: Connect one end of the Ethernet cable to the MGMT port of the device, and the other end to the NMS or a
control terminal.
Step 2: Insert the single-mode or multi-mode fiber into the appropriate port according to the identification on the panel of
the module.
Step 3: Insert the twisted pair with the RJ45 connector into the appropriate port according to the identification on the
panel of the module. Distinguish the crossover cable and straight-through cable.
3.6 Bundling the Cables
Precautions
The power cables and other cables should be bundled in a 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 hard the fibers and affect their service time and
transmission performance.
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 bottom of the chassis, in a straight line wherever
possible.
3.7 Checking after Installation
Before checking the installation, switch off the power supply to avoid any personal injury or damage to the
component due to connection errors.
Check that the ground line is connected.
Check that the cables and power input cables are correctly connected.
Check that all interface cables are laid out inside the equipment room. In the case of external cabling, check that
the lightning resistance socket or network interface lightning protector is connected.
