Grounding Requirements - D-Link DGS-6600 Series Hardware Installation Manual

DGS-6600 Layer 3 Chassis Ethernet Managed Switch Hardware Installation Guide

Grounding requirements

Proper grounding of the switch will help ensure stable and reliable operation of the DGS-6600 series switch. it is
important to verify that the grounding conditions during and after installation of the switch meet the grounding
requirements and grounds all devices properly.
All grounding conductors should be connected before the AC power is applied to the DGS-6600 series switch
installed AC power supplies.
The DGS-6604 series switch with AC power supplies must be grounded with a minimum of 0.823 mm
18AWG) of conductive grounding cable. This cable is connected between the Equipment Room Ground and the
DGS-6600 series Chassis Ground Terminal.
The DGS-6608 series switch with AC power supplies must be grounded with a minimum of 1.32 mm2
(or16AWG) of conductive grounding cable.
CAUTION: Indirectly or directly contacting the mains supply with a wet object can
cause a fatal danger.
CAUTION: Hazards, including electrical shocks and fires, can be caused by any
non-standard and inaccurate electrical operation. This may cause severe or fatal
damage to the human body or equipment.
Preventing Static Discharge Damage
While all precautions have been taken with the design of the DGS-6600 series switch to prevent damage from
static electricity, if the static electricity exceeds a certain limit, damage may be caused to the Switch's circuitry
and equipment.
Electrostatic induction may come from the following sources on the network that the DGS-6600 series switch is a
member of:
• External electric fields produced by high-voltage cable supplies, lightning etc.
• Internal building factors, such as the internal floor or the building structure.
The following factors must be paid attention to in order to prevent damage from static electricity: To prevent
damage from static electricity, please use the following guidelines:
1. Be sure to install an adequate ground for all electronic equipment.
2. Use appropriate dust prevention measures.
3. Maintain the required humidity in the operating environment.
4. Hold circuit boards by their edges. Do not touch any components on the printed circuit board (PCB).
5. Always wear an anti-static wrist strap when working near any electronic circuitry.
6. Do not allow clothing to touch circuit boards. An antistatic wrist strap will only prevent static electricity from
the human body, it will not reduce the static electricity build up on clothing.
