D-Link 180W (54 V DC Output) Power Supply with Rack-Mount Kit for DIS-200G Switch Series - (DIS-200G-RPK180)

The DIS-200G power adapter is optional and purchased separately. Connecting to a Power Source - The DIS-200G Series switches can be powered using this power adapter (optional) or by using the built-in terminal connector. This allows dual power inputs using wires from the power source(s) screwed into the terminal connections. Connect the power adapter (if included) to the power connector on the back of the switch. Connect the other end of the power adapter to a main power source. Please note that multiple power sources connected to the switch cannot supply power to the Switch at the same time. For example, when two 120 W power sources are connected to PWR1 and PWR2 on the switch, the switch will only take 120 W power from the power source that was connected first, while the second power source serves as a backup.
