Power Management
IPDU Power Management
IPDU power management allows authorized users to control power for
devices that are plugged into an AlterPath PM intelligent power distribution
unit (IPDU), when the IPDU is connected to one of the OnSite’s two AUX
ports and properly configured.
Multiple AlterPath PM intelligent power distribution units (IPDUs) can be
daisy-chained to allow power management of up to a total of 128 outlets per
AUX port. Since both AUX ports can be used for IPDU power management,
you can plug in and manage up to 256 devices.
When a device is physically connected to either a serial port or KVM port and
plugged into an IPDU, authorized users can manage power for that device
while connected to a serial or KVM port to which the device is physically
connected.
When a device with multiple power supplies is connected to a serial port, the
device can be plugged into multiple outlets on daisy-chained IPDUs, and
authorized users can managed all outlets as a group.
Power Management While Connected to Devices
Authorized users can do the following types of power management while
connected to a device through one of the OnSite’s ports:
• Users can perform IPDU power management of a connected server while
logged into the server through a KVM port.
• Users can perform IPDU or IPMI power management of a connected
device while logged into the device through a serial port.
Power Management from the OnSite Command Line
OnSite administrators can use the following commands to manage power:
•The pm, pmCommand commands for performing IPDU power
managment
• ipmitool commands to manage power on IPMI devices.
The pm and pmCommand commands are introduced in “Managing IPDU
Outlets With PM Commands” on page 119.
