Understanding How Power Management Works
Power Cycling Modules
You can power cycle (reset) a module from global configuration mode by entering the
power cycle
module
slot
command. The module powers off for 5 seconds, and then powers on.
Determining System Power Requirements
The power supply size determines the system power requirements. When you use the 1000 W and
1300 W power supplies, you might have configuration limitations depending on the size of chassis and
type of modules installed. For information about power consumption, refer to the
Release Notes for
Cisco IOS Release 12.2SX on the Supervisor Engine 720, Supervisor Engine 32, and
Supervisor Engine 2
.
Determining System Hardware Capacity
With Release 12.2(18)SXF and later releases, you can determine the system hardware capacity by
entering the
show platform hardware capacity
command. This command displays the current system
utilization of the hardware resources and displays a list of the currently available hardware capacities,
including the following:
•
Hardware forwarding table utilization
•
Switch fabric utilization
•
CPU(s) utilization
•
Memory device (flash, DRAM, NVRAM) utilization
This example shows how to display CPU capacity and utilization information for the route processor,
the switch processor, and the LAN module in the Cisco 7600 series router:
