Module power consumption and total power
consumption

Total power consumption

The total power consumption is the system power consumption plus PoE power consumption.
The system power consumption is the sum of the power consumption of all running cards and the
•
power consumption of all fans.
The PoE power consumption is the sum of the power consumption of all PDs connected to the switch.
•
Card power consumption
The power consumption of the cards of the S7500E series depends on the card model and state.
33 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
All S7500E series switches except the S7503E-S adopt 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.
fan trays.
System power consumption
The system power consumption of an S7500E 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 S7503E switch that has two LSQ1SRPB0
(LSQM1SRPB0) switching and routing processing units (SRPUs), three LSQ1GV48SC0
(LSQM1GV48SC0) LPUs, and one fan tray, the minimum system power consumption of the switch
is 2 × 42 + 3 × 60 + 15.5 = 279.5 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 S7503E switch that has two
LSQ1SRPB0 (LSQM1SRPB0) SRPUs, three LSQ1GV48SC0 (LSQM1GV48SC0) line processing
units (LPUs), and one fan tray, the maximum system power consumption of the switch is 2 × 50 + 3
× 90 +27.5 = 397.5 W.
