Monitor the Power Budget
The power budget is the amount of power available from the installed PSUs minus the power required to operate the port
extender.
To help determine if power is available for additional PoE or PoE+ ports, use the show power inline and show power
detail commands. For information about these commands, see Displaying PoE Power Allocation.
The C1048P PE has one 1000 W fixed PSU and one external power supply with a capacity of 1000 W. The power required for
system components is 150 W. The power available for PoE or PoE+ is calculated after excluding the power needed for system
components and power redundancy.
The following table defines the power budgeting for PE. In this table, 150 W from the fixed PSU and EPS are reserved for
system power and redundancy. The remaining 850 W from each PSU is allotted for PoE or PoE+.
