QSW-6300 Series Switches Hardware Installation and Reference Guide
Installing the Switch

3.5. Connecting the Ground Cable of the Switch
A PGND is installed on the back of QSW-6300
（
M5*12PWM screws. First connect the PGND to
the grounding terminal of the cabinet and then connect the grounding terminal to the grounding
bar of the equipment room.
Precautions:
The cross-sectional area of the ground cable should be determined according to the
possible maximum current. Cables with good conductor should be used.
Do not use bare wire.
To ensure human safety and device security, the switch must be properly grounded.
The resistance between the chassis and ground should be less than 1 ohm.
Note:
To ensure human safety and device security, the switch must be properly grounded.
The resistance between the switch chassis and ground should be less than 1 ohm.
Please check whether the AC socket of the switch is reliably connected to the protection
ground of the building. If not, please use a protection ground wire to connect the
protection ground terminal of the AC socket to the protection ground of the building.
The power socket should be installed in an easily operable position near the switch.
During the device installation, always make the ground cable connected first and
disconnected last.
The cross-sectional area of the protection ground cable should be at least 2.5 mm2 (12
AWG).
3.6. Connecting the External Interface Cables
Precautions:
Correctly distinguish single-mode and multi-mode fibers and ports.
Avoid bends of small curvature at the connector.
3.6.1. 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.
3.7. 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.
