System Power

ztC Endurance systems have one power button located on the control-panel earClosed A module located at the front right of the ztC Endurance system. It houses a USB 2.0 port, power button for the ztC Endurance system, and LEDs that indicate system power status (PWR), fault conditions (ATTN), and module identification status (UID).. Press this button to start the system.

Pressing the Power Button

The system power button functions as follows, assuming both compute modulesClosed A customer-replaceable unit (CRU) located at the front of the ztC Endurance system. It is equipped with processors, RDIMMs, BIOS, BMC, fans, and other technology to boot and run the ztC Endurance system. Each system contains two compute modules. are in the same state:

Note: The power button affects both compute modules. Therefore, if one compute module is powered off and one is booted, pressing the power button results in one compute module turning on and the other shutting down.

Starting Up the System

Make sure the system power cords are plugged into a live power source.

To boot a system and start the operating system

  1. Turn on the monitor.

  2. Press the power button on the control-panel ear. See Figure 27.

Shutting Down the System

Warning: The system's standby devices have power even after the system has been powered down. To remove power to the standby devices, you must remove the power cords.
Avertissement: Les appareils de réserve du système restent alimentés même après l'extinction du système. Pour couper l'alimentation des appareils de réserve, vous devez enlever les cordons d'alimentation.

Exit from all applications before shutting down a system.

Do one of the following to shut down a Windows-based system gracefully:

  • From the Windows Start menu, select Shut down or Restart.

  • Click Shutdown on the Dashboard page of the ztC Endurance console​.

  • Press the power button on the control-panel ear momentarily.

Notice: Do not use the BMC Web console to power off a running ztC Endurance system. See Unsupported BMC Web Console Features for more information.

When you shut down a Windows-based system, note that the following behavior is normal:

  • The system stays powered on for several minutes, as all services are stopped and cached data is written to disk.

  • The Ethernet activity and connection-speed LEDs for embedded Ethernet ports may remain lit even when the system is powered down, if Wake On LAN is enabled in the system BIOS.

    Note: Wake On LAN is supported only for the host's or BMC's connection to the 1G management network.

Enabling and Disabling Wake on LAN

The Wake On LAN (WOL) networking standard allows a computer to be turned on or awakened from sleep mode remotely via a network message.

The following instructions allow you to enable or disable WOL for ports on your ztC Endurance system.

Notice: Do not change any other BIOS settings unless Stratus Customer Service has advised you to do so.

To enable WOL

  1. As the system starts to boot, press either the Delete key or the Esc key until the system BIOS setup utility appears.

  2. When the utility screen appears, use the arrow keys to go to the Advanced menu.

  3. Select Intel(R) i210 Gigabit Backplane Connection and press Enter.

  4. Select NIC Configuration and then select the port that you want to enable. Press Enter.

  5. Use the +/= keys to change Wake On LAN to Enabled and press Enter.

  6. Press F4 to save your changes and exit the utility.

To disable WOL

  1. Download the Intel® Ethernet Flash Firmware Utility (BootUtil) from the following Web site:

    https://www.intel.com/content/www/us/en/support/articles/000005790/software/manageability-products.html

  2. Use the -WOLDISABLE or -WOLD option of BootUtil to disable WOL functionality on the selected port, as described in the preceding Web site.
