Power On; Connect To Dc Power Plug - D-Link DGS-3710 Series Hardware Installation Manual

DGS-3710 Series Layer 2 Managed Gigabit Switch Hardware Installation Guide

Power On

1. Connect the AC or DC power cord into the power connector of the Switch and the other end into the local
power source outlet.
2. Turn on the power switch, located on the front panel of the device, to power on the Switch.
3. After powering on the Switch, the LED indicators will momentarily blink green. This blinking of the LED
indicators represents a reset of the system.
NOTE: When the AC power and DC power are on at the same time, the AC power will take higher
priority than the DC power.

Connect to DC Power Plug

The DGS-3710 Series Switch supports a unique Dual Power Input feature. Next to the AC Power plug we find a DC
power plug. Here the user can connect a -48V DC power source that will be activated when the AC power is not
working.
Please make sure that connection polarity (positive and negative) is correct before using this feature to avoid any
damaged.
Connect the power source to the DC plug before plugging it into the Switch. This will protect Switch from a possible
shortage on the DC cable.
