Introduction

HDM supports power management. You can view and remotely manage the power status of the server, edit AC recovery settings, view power information, set server power alarm thresholds, and configure power capping. This document describes how to manage power supplies from HDM.

Prerequisites

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every setting on your network.

The following information is provided based on the assumption that you have basic knowledge of power management.

Application scenarios

This document is applicable to scenarios where you manage power supplies and power settings for the server from HDM to efficiently reduce power consumption of the server to implement energy saving for the server.

Example: Managing power supplies

Network configuration

As shown in Figure 1, the HDM management interface of H3C UniServer R4900 G6 (R4900 G6) connects to the PC through a switch, ensuring normal network communication. You can log in to the HDM Web interface on the PC to manage power supplies to achieve energy saving for the server.

·     HDM information for the R4900 G6 server is as follows:

¡     IP address: 192.168.20.177.

¡     Administrator account: admin.

¡     Administrator password: Password@_.

·     IP address of the PC: 10.41.50.29.

Figure 1 Network diagram

 

Analysis

Log in to the HDM Web interface for the R4900 G6 server. Then, you can power on or power off the server, set the power supply operating mode, view power consumption information, configure power alarming, and configure power capping from the Web interface.

Software versions used

This configuration example was created and verified on HDM2-1.54.

Procedures

Logging in to the HDM Web interface

1.     Open the browser on the client and enter HDM management IP address 192.168.20 to access the HDM Web interface.

2.     On the HDM login page, enter the default administrator username (admin) and password (Password@_), as shown in Figure 2.

Figure 2 Logging in to the HDM Web interface

 

3.     On the top navigation bar, click System.

4.     In the left navigation pane, select Power Management, as shown in Figure 3.

Powering on or powering off the server

	NOTE: ·     The force power-off, force system reset, and force power-cycle actions might cause corruption or loss of data. When you perform these actions, make sure you fully understand their impact on the services. ·     With the physical power button disabled, you cannot perform power actions by pressing the power button on the chassis ear.

 

1.     On the Power Status tab, the Power status field displays the current power status of the server. You can click the following buttons as needed:

¡     Force system reset: Warm reboots the server without power cycling the server. During this process, the power to the server will not be disconnected.

¡     Force power-off: Shuts down the server immediately by force. This action is equivalent to pressing the power button on the server for at least five seconds. During this process, the power to the server will be disconnected.

¡     Graceful power-off: Shuts down the operating system first, and then removes power from the server. During this process, the power to the server will be disconnected.

¡     Power on: Starts up the server.

¡     Force power-cycle: Powers off and powers on the server. During this process, the power to the server will be disconnected.

2.     To shield the physical power button of the server, click Disable physical power button. With the physical power button disabled, users cannot use the physical power button to manage the power status of the server.

3.     In the System power restore area, configure the power-on policy and set the power-on delay, as shown in Figure 5.

¡     Power-on policy:

-     Always power on: Have the server always automatically start up when it is connected to the power source.

-     Always power off: Have the server stay off when it is connected to the power source, select.

-     Restore last power state: Have the server return to the power state on the previous power-off. This option is the default.

¡     Power-on delay: Set the power-on delay time. If you select Random, you can customize the delay time range.

Setting the power supply operating mode

1.     Click the Power Supply Info tab.

2.     Click Power Settings.

3.     In the dialog box that opens, select Active/standby, and then specify active power supplies, as shown in Figure 6.

If an active power supply fails or the actual power consumption of an active power supply exceeds 62% of its maximum rated power consumption, a standby power supply becomes active to supply power.

Viewing power supply information

1.     To view the input voltage history, click the Power Supply Info tab and click the voltage icon , as shown in Figure 7.

Figure 7 Viewing the input voltage history

 

2.     To view power consumption information in the past 24 hours, click the Power Consumption tab, select Past 24 hours, and then click OK.

Configuring power alarming

1.     Click the Power Consumption tab.

2.     Click  in the Power alarming section.

3.     In the dialog box that opens, enable power alarming, specify the alarm threshold, and then click OK.

Configuring power capping

CAUTION: ·     Set reasonable power cap values. If a power cap is too low, power capping failures might occur. ·     Server shutdown upon a power capping failure causes service interruption. To use this function, make sure you understand the impact. ·     To avoid GPU node power capping configuration invalidity, make sure the GPU driver is installed in the OS before you configure GPU node power capping settings.

 

1.     Click the Power Consumption tab.

2.     Click  in the System board power capping section.

3.     In the dialog box that opens, enable power capping, set the power cap value, and select No for Shutdown on capping failure. Then, click OK.

Verifying the configuration

After you configure power alarming and power capping, click the Power Consumption tab to verify the power consumption settings, as shown in Figure 10.
