System power consumption
The system power consumption of the device depends on the type and number of modules and the
fan tray power consumption.
•
The minimum system power consumption is the total static power consumption of all modules
plus the minimum fan tray power consumption.
•
The maximum system power consumption is the total dynamic power consumption of all
modules plus the maximum fan tray power consumption.
For example, for an S12516R that has two LSXM1SUPER1 MPUs, two LSXM1CGQ36HBR1
interface modules, six LSXM2SFH16CR1 fabric modules, and two LSXM116XFANH fan trays, the
minimum system power consumption of the device is 2 × 52 + 2 × 608 + 6 × 194 + 2 × 187 = 2858 W.
The maximum system power consumption of the device is 2 × 70 + 2 × 1070 + 6 × 308 + 2 × 2570 =
9268 W.
Heat dissipation
Heat dissipation is measured in BTU/h, and 1 W equals 3.4121 BTU/h.
The heat dissipation of a device depends on its power consumption. To calculate heat dissipation of
the device, assume 90% power consumption is converted to heat, and the efficiency of the power
module is 90%. Heat dissipation/hour of the device is 0.9 × (total power consumption of the modules
plus power consumption of the fan tray)/0.9 × 3.4121.
