System power consumption
The system power consumption of the switch depends on the type and number of cards and the fan tray
power consumption.
•
The minimum system power consumption is the total static power consumption of all cards plus the
minimum fan tray power consumption. For example, for an S10508 switch that has two LSU1SUPA0
(LSUM1SUPA0) MPUs, two LSU1TGX4EB0 (LSUM1TGX4EB0) LPUs, two LSU1FAB08A0
(LSUM1FAB08A0) switching fabric modules, and one fan tray, the minimum system power
consumption of the switch is 2 × 38 + 2 × 53 + 2 × 68 + 11 = 329 W.
•
The maximum system power consumption is the total dynamic power consumption of all cards plus
the maximum fan tray power consumption. For example, for an S10508 switch that has two
LSU1SUPA0 (LSUM1SUPA0) MPUs, two LSU1TGX4EB0 (LSUM1TGX4EB0) LPUs, two
LSU1FAB08A0 (LSUM1FAB08A0) switching fabric modules, and one fan tray, the maximum system
power consumption of the switch is 2 × 50 + 2 × 80 + 2 × 85 +234 = 664 W.
Heat dissipation
Heat dissipation is measured in BTU/h, and 1 W equals 3.4121BTU/h.
The heat dissipation of a switch depends on its power consumption. To calculate heat dissipation of the
switch, assume 90% power consumption is converted to heat, and the efficiency of the power module is
90%. Heat dissipation/hour of the switch is 0.9 × (total power consumption of the cards plus power
consumption of the fan tray)/0.9 × 3.4121.
