5. Product Overview Time-based PoE* : Shuts down power automatically during off-work hours. The following table shows the amount of energy you can save in a scenario where 8pcs of DCS-7510 are connected to DGS- 1210-10P. Each DCS-7510 consumes 7.95w and the power saving a day is based on a standard workday of 10 hours powered on and 14 hours powered off. If the DGS-1210-10P is enabled with time-based PoE, it can achieve up to 54% saving per day or 65% saving per week. Test condition 1: - Power (w) with 8 ports link down, no load, PoE off. - 1-8 ports link down, no traffic, 9- 10 ports no connection, total PoE load 0W. Test condition 2: - Power (w) with 8 ports link up, full load, PoE on. - 1-8 ports link up, 1000M traffic, 9-10 ports no connection, total PoE load 63.6W.
