Module power consumption and system power
consumption
System power consumption
Card power consumption
The power consumption of the cards depends on the card model and state. Table 15 shows the power
consumption for different card models.
• The static power consumption of a card refers to the power consumed by the card when the card is
running but all ports on the card are down and when no transceiver module is available on the
optical interface of the card.
•
The dynamic power consumption of a card refers to the power consumed by the card when all the
ports on the card are fully configured and send broadcasts.
Fan tray power consumption
The switch uses fans with the automatic speed adjustment function. The fan speed is automatically
adjusted based on the heat dissipation condition of the switch. The power consumed by a fan tray
depends on the fan speed.
Table 16 shows the power consumption of different fan trays.
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 S7508E-X switch that has two
LSQ1SUPA0 (LSQM1SUPA0) MPUs, two LSQ1TGX4EB0 (LSQM1TGX4EB0) LPUs, two
LSQ1FAB08A0 (LSQM1FAB08A0) 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 S7508E-X switch that has two
LSQ1SUPA0 (LSQM1SUPA0) MPUs, two LSQ1TGX4EB0 (LSQM1TGX4EB0) LPUs, two
LSQ1FAB08A0 (LSQM1FAB08A0) 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.
