Power On; Power Failure; External Redundant Power System - D-Link DGS-3024 Manual

Power on

The Switch can be used with AC power supply 100-240 VAC, 50 - 60 Hz. The Switch's power supply will adjust to the local
power source automatically and may be powered on without having any or all LAN segment cables connected.
After the Switch is plugged in, the LED indicators should respond as follows:
•
All LED indicators except console will momentarily blink. This blinking of the LEDs indicates a reset of the system.
•
The console LED indicator will blink while the Switch loads onboard software and performs a self-test. When the POST
is passed, the LED will become dark. If the POST fails, the indicator will light solid amber. This indicator lights solid
green when the Switch is being logged-in via out-of-band/local console management through the RS-232 console port
using a straight-through serial cable.

Power Failure

As a precaution in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in.

External Redundant Power System

The Switch supports an external redundant power system.
