Ruijie RG-NBS5100 Series Switches Hardware Installation and Reference Guide
Product Installation
22
To guarantee the security of the body and the device, the switch must be well-grounded. The grounding resistance
for combined grounding should be
less than 1Ω.
The maintenance personnel shall check whether or not the AC socket powering the switch is well connected to the
building protective earth (PE). If not, the personnel shall connect the grounding lug of the AC socket with the PE by
using a grounding connector.
The AC socket shall be installed near the equipment and shall be easily used.
When installing the switch, make sure the grounding is connected first and disconnected last.
The cross-sectional area of PE conductor shall be at least 2.5 mm
2
(12AWG).
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.
