Front panel LEDs and buttons

Item	Description	Status
1	UID button/LED	Solid blue = Activated Flashing blue: 1 flash per second = Remote management or firmware upgrade in progress 4 flashes per second = iLO manual reboot sequence initiated 8 flashes per second = iLO manual reboot sequence in progress Off = Deactivated
2	Health LED	Solid green = Normal Flashing green (1 flash per second) = iLO is rebooting Flashing amber = System degraded Flashing red (1 flash per second) = System critical   If the health LED indicates a degraded or critical state, review the system IML or use iLO to review the system health status.
3	NIC status LED	Solid green = Link to network Flashing green (1 flash per second) = Network active Off = No network activity
4	Power On/Standby button and system power LED	Solid green = System on Flashing green (1 flash per second) = Performing power on sequence Solid amber = System in standby Off = No power present   Facility power is not present, power cord is not attached, no power supplies are installed, power supply failure has occurred, or the front I/O cable is disconnected.

When all four LEDs described in this table flash simultaneously, a power fault has occurred. For more information, see "Front panel LED power fault codes" in the HPE ProLiant ML350 Gen9 User Guide.

Install hardware options

Install any hardware options before initializing the server. For options installation information, see the documentation that ships with the option. For server-specific information, see the HPE ProLiant ML350 Gen9 Server User Guide on the Hewlett Packard Enterprise website.

Connect cabling and power cords

1. Connect iLO management cabling.

   

2. Connect the network cabling.

   

3. Connect the power cord to the power supply.

   

   WARNING: To reduce the risk of electric shock or damage to the equipment: Do not disable the power cord grounding plug. The grounding plug is an important safety feature. Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times. Unplug the power cord from the power supply to disconnect power to the equipment. Do not route the power cord where it can be walked on or pinched by items placed against it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends from the server.

For more information about cabling the system, see the HPE ProLiant ML350 Gen9 Server User Guide on the Hewlett Packard Enterprise website.

Power up and select boot options

On servers operating in UEFI Boot Mode, the boot controller and boot order are set automatically.

1. Press the Power On/Standby button.
2. During the initial boot:
   • To modify the server configuration ROM default settings, press the F9 key in the ProLiant POST screen to enter the UEFI System Utilities screen. By default, the System Utilities menus are in the English language.
   • If you do not need to modify the server configuration and are ready to install the system software, press the F10 key to access Intelligent Provisioning.

For more information on automatic configuration, see the UEFI documentation on the Hewlett Packard Enterprise website.

Install the system software

This ProLiant server does not ship with provisioning media. Everything needed to manage and install the system software and firmware is preloaded on the server.

To operate properly, the server must have a supported operating system. Attempting to run an unsupported operating system can cause serious and unpredictable results. For the latest information on operating system support, see the Hewlett Packard Enterprise website.

Failure to observe UEFI requirements for ProLiant Gen9 servers can result in errors installing the operating system, failure to recognize boot media, and other boot failures. For more information on these requirements, see the HPE UEFI Requirements on the Hewlett Packard Enterprise website.

To install an operating system on the server, use one of the following methods:

• Intelligent Provisioning—For single-server deployment, updating, and provisioning capabilities.

  To install an operating system on the server with Intelligent Provisioning (local or remote):

  1. Connect the Ethernet cable between the network connector on the server and a network jack.
  2. Press the Power On/Standby button.
  3. During server POST, press F10.
  4. Complete the initial Preferences and Registration portion of Intelligent Provisioning.
  5. At the 1 Start screen, click Configure and Install.
  6. To finish the installation, follow the onscreen prompts. An Internet connection is required to update the firmware and systems software.
• Insight Control server provisioning—For multi-server remote OS deployment, use Insight Control server provisioning for an automated solution. For more information, see the Insight Control documentation on the Hewlett Packard Enterprise website.

For additional system software and firmware updates, download the Service Pack for ProLiant from the Hewlett Packard Enterprise website. Software and firmware must be updated before using the server for the first time, unless any installed software or components require an older version.

Register the server

To experience quicker service and more efficient support, register the product at the Hewlett Packard Enterprise Product Registration website.
