Description of the problem

OSN 3500 single-subrack power consumption 760W, single-subrack insurance is generally selected 20A, insurance capacity when the type III (2300W) subrack supporting N1PDU/DPD100-2-8 PDU, the power consumption threshold of the device can only reach 1100W, so it is recommended that the type III (2300W) subrack supporting TN51PDU/DPD63-8-8 PDU. different. subrack types support the same service veneer, but the maximum number of the same service veneer that can be configured in a single subrack is related to the power consumption of the subrack.

OptiX OSN1500 Power Consumption Matching Strategy

OSN 1500 single subrack power consumption 280W, single subrack insurance generally choose 10A. different subrack types support the same service board, but the same service board in a single subrack can be configured in the maximum number of subrack power consumption is related to the subrack. The maximum power consumption of the subrack indicates the maximum power consumption configuration that the subrack can withstand and the maximum heat dissipation capability of the subrack. Typical configurations in practice consume much less power than this value.

OptiX OSN2500 Power Consumption Matching Strategy

The OSN 2500 single subrack power consumption is 350W, and the single subrack insurance is usually selected as 15A. For an OSN 3500/2500 cabinet, the 32A or 40A insurance is usually selected. This is true for both R1/R2 versions, but be aware that these values will change later when some high power single boards are developed. As the features supported by the device continue to increase, the power consumption of the device increases accordingly. In order to ensure the normal operation of the device, the internal power supply system of the device provides different power consumption matching strategies according to different power consumption requirements. The internal power supply system of the device consists of PDU and PIU.
