DGS-6600 Layer 3 Chassis Ethernet Managed Switch Hardware Installation Guide
• Avoid carrying out maintenance on the equipment alone when the Switch is powered on.
• Before shutting down the power supply, check that it is safe to do so.
• Do not place the Switch in a damp/wet location. Ensure that no liquid enters the chassis.
• Ensure that all grounding conductors are connected both before, and after the line and neutral (AC)
conductors are connected.
• Disconnect all power supply cords before servicing.
• Connect the power cable to a circuit breaker rated not greater than 20A.
• When installing multiple power supplies, connect each power supply to a different, independent over-
current protection device, such as a circuit breaker. If a single power source fails, it will affect only the
power supply to which it is connected.
