Total power consumption
For the S7506E-S, S7506E (non-PoE), the total power consumption of the switch equals its system power
consumption.
For the S7502E, S7503E-S, S7503E, S7506E, S7506E-V, or S7510E, the total power consumption of the
switch equals its system power consumption plus its PoE power consumption.
System power consumption
The system power consumption of the switch depends on the type and number of the running 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, an S7503E switch is installed with two
LSQM2MPUC0 MPUs, three LSQ3GV48SC0 (LSQM3GV48SC0) LPUs, and one fan tray. The
minimum system power consumption of the switch is 2 × 38 + 3 × 67 + 15.5 = 292.5 W.
• The maximum system power consumption is the total dynamic power consumption of all cards plus
the maximum fan tray power consumption. For example, an S7503E switch is installed with two
LSQM2MPUC0 MPUs, three LSQ3GV48SC0 (LSQM3GV48SC0) LPUs, and one fan tray. The
maximum system power consumption of the switch is 2 × 63 + 3 × 95 +27.5 = 438.5 W.
Table 19 lists the max power consumption for each model of the S7500E in full and max configuration.
• Max system power consumption (full and max configuration)—Max system power consumption
when the switch is fully configured with cards that have the highest power consumptions.
• Max card and fan tray power consumption (full and max configuration)—Max card and fan tray
power consumption when the switch is fully configured with cards and fan trays that have the
highest power consumptions.
