Connecting External Cables; Bundling Cables - Ruijie Reyee RG-NBS3100-24GT4SFP-V2 Installation Manual

Installation Guide
 The grounding electric resistance should be less than 1 Ω.
Cauiton

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 1 Ω.

The maintenance personnel must check whether the AC socket powering the switch is well connected to
the building protective earth (PE). If not, the personnel must connect the grounding lug of the AC socket to
the PE with a grounding connector.

The AC socket must be installed near the device and easily used.

When installing the switch, ensure that the grounding is connected first and then disconnected.

The cross-sectional area of the PE conductor must be at least 2.5 mm

Connecting External Cables

Precautions

Correctly distinguish single-mode and multimode fibers and ports.

Avoid bends of the 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 multimode 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.

Bundling Cables

Precautions

The power cables and other cables must be well bundled.

When you bundle fibers, make sure that the fibers at the connectors have natural bends or bends of the
large radius.

Do not bundle fibers and twisted pairs too tightly because 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 both sides of the chassis, fasten the fibers and twisted pairs to the cabinet cable management ring or
cabling chute.

For power cables, bundle them closely along the bottom of the chassis, in a straight line wherever possible.
