Installation procedure
11 Installing Dell EMC OpenManage Essentials
• IIS 7.5/8
• Microsoft .NET 3.5 SP1
• ASP.NET 4.6.2
• Microsoft Silverlight 5.1.50907
• Microsoft Visual Studio® Runtime 14.0
• BMC Utilities 9.0.1
• DRAC Tools 9.0.1
• PowerShell 2.0
• TLS 1.1/1.2
o With the latest iDRAC or CMC firmware (iDRAC >= 2.40.40.40, M1000e CMC >= 5.2, FX2 CMC
>= 1.4, VRTX CMC >= 2.2), TLS 1.1 is the default communication protocol. Therefore, TLS 1.1
and TLS 1.2 must be enabled as default secure protocols in WinHTTP in the management station
where OME is going to be installed.
o Though this is not a critical prerequisite, it is required for OME to successfully discover and
inventory the iDRACs and CMCs with latest firmware.
o This prerequisite is only on Microsoft Windows 2008 R2 and Microsoft Windows 2012. In
Microsoft Windows 2012 R2 and later versions, these protocols are enabled by default.
Note—The OME installation is not based on the Windows SNMP service. If the SNMP service is disabled
or stopped, the installation will not be affected. If the SNMP Trap service is configured in manual mode
and disabled, the Prerequisites window displays a warning prerequisite. If you ignore the warning and
proceed with the installation, OME will not be able to receive SNMP traps/alerts.
To enable the SNMP traps or alerts reception functionality after installation:
1. Manually enable and start the Windows SNMP Trap service from Service Control Manager.
2. On the OpenManage Essentials page, click Preferences  Console Settings.
3. Click Restart Services.
Note:
• If the SQL server is not available in the system, in which OME is being installed, a message with
a link to install SQL Express is displayed.
• If you ignore this message, you will be prompted to install the OME on local or remote database
while starting the installation.
• If you need to continue installing OME on the local database, select Yes. The SQL Express will
be installed with the SQLEXPRESSOME instance name.
• If you need to install OME on the remote database, Select No. The installer will follow the Custom
installation path, where you have to select the remote database for installing the OME.
