Keep the handle of the optical module closed, use your thumb and forefinger to hold two sides of the
optical module, and gently pull the optical module.
1. If the optical module is not pulled out, it has been correctly installed.
2. If the optical module is pulled out, it is installed incorrectly. Install the optical module again.
Hardware Installation and Parts Replacement
Switch Hardware Installation and Maintenance Guide
• Check whether the optical module is securely seated in the optical port.
1.5.1 Connecting the Grounding Cable
1.5 Connecting a Switch
There is one ground terminal on the back of the S5860 series switches chassis, which should be connected to
the grounding lug of the rack first, and then connect the grounding lug to the grounding bar of the equipment
room.
• To guarantee the security of the person and the equipment, the switch must be grounded properly.
The grounding resistance between the chassis and the ground should be less than 1Ω.
• The maintenance personnel should check whether the AC socket is reliably connected to the
protective ground of the building. If not, the maintenance personnel should use a protective ground
conductor from the AC outlet protective ground terminal to the building protective ground.
• The power socket should be installed near the equipment and easily accessible.
• When installing the switch, connect the grounding first and disconnect it last.
• The cross-sectional area of the protection ground wire should be at least 2.5mm2 (12AWG).
• The cross-sectional area of the grounding wire should be determined based on the maximum current load
that may pass through it, and it should be made of a good conductor.
• Do not have bare wires exposed.
• Grounding resistance: Less than 1Ω.
Precautions
1.5.2 Connecting Power Cables
• To avoid electric shock, do not connect the power cable while the power is on.
• Please take appropriate anti-static precautions, such as wearing an anti-static wristband or anti-static
gloves.
• Power cables must be buried underground or routed indoors and can not be led into the equipment room
aerially.
• Do not power on a switch before you finish installing the switch and connecting cables.
