Power consumptions
Card power consumption
The power consumption of a card depends on the card state.
• Static power consumption (min)—Power consumed by a card when the card is running but all ports
on the card are down and no transceiver modules are installed on the fiber ports of the card.
• Dynamic power consumption (max)—Power consumed by a card when the card is fully configured
and sends broadcasts at wire speed.
Table 11 Card power consumption
Model Static power consumption Dynamic power consumption
LSV1QGS12SA1 160 W 230 W
LSVM1SRPC1 185 W 245 W
LSVM1SRPA1 94 W 110 W
LSV1TGS24SA1 75 W 100 W
LSVM1QGS12FX1 160 W 230 W
LSVM1TGS24FX1 75 W 100 W
LSVM1QGS6C2FX1 121 W 190 W
LSV1MPUA1 (main processing unit on
the S9804 switch)
334 W 350 W
Fan tray power consumption
The switch fan trays can automatically adjust the fan speed based on the heat dissipation condition of the
switch. The power consumed by a fan tray depends on the fan speed.
Table 12 Fan tray power consumption
Model Minimum power consumption Maximum power consumption
S9804 fan tray 18 W (40% speed) 130 W (100% speed)
S9810 fan tray 20 W (40% speed) 180 W (100% speed)
System power consumption
The system power consumption of the switch depends on the type, number, and power consumption of
the cards and fan trays.
• Minimum system power consumption—Static power consumption of all cards + Minimum power
consumption of all fan trays.
For example, for an S9804 switch that has four LSV1QGS12SA1 LPUs and two S9804 fan trays,
the minimum system power consumption is: 334 (minimum power consumption of the main
processing unit LSV1MPUA1) + 4 × 160 + 2 × 18 = 1010 W.
