Power Center Services in Windows

Power Center includes the following services:

• Dell OpenManage Power Center – The Apache Tomcat server that hosts the Power Center web application

which passes action requests to the Power Center server.

• Dell OpenManage Power Center Database Server – The PostgreSQL internal database for Power Center.

• Dell OpenManage Power Center SNMP Dispatcher – If the Windows SNMP trap service is installed, then it

reroutes SNMP traps to the Dell OpenManage Power Center Server service. If the Windows SNMP trap service

is not installed, this service will automatically stop.

NOTE: If the Windows SNMP trap service is installed, make sure it is not disabled. Otherwise, Power

Center cannot function properly.

• Dell OpenManage Power Center Server – The Power Center server core service. It carries out all actions

including communication with devices.

To stop or start a service, select the appropriate service from the Windows Services list, and select the action to

perform.

Power Center uses the Network Service account to start all services. You can change to a normal Windows operating

system user account for security purposes. For more information on how to change the account, see Starting Services

with a Normal Windows OS User Account.

Upgrading

To upgrade Power Center from a previous version, the system must meet the following minimum requirements:

• At least 363 MB of free space on the C: drive

• Running Windows Server 2008 or later

1. Install OpenManage Power Center. For more information, see Installing Power Center.

A dialog box displays, informing you that an older version of OMPC is installed.

2. If you want to migrate the previous Power Center database, ensure that Migrate previous data check box is

selected. This will migrate most of the Power Center data, such as hierarchy information, monitoring history, policy

settings, events, and credential data.

3. To upgrade, click Upgrade now. If you do not want to upgrade, click Cancel.

Uninstalling Power Center In Windows

NOTE: Make sure to remove all devices from the Power Center management console before uninstalling Power

Center. Otherwise, the existing power cap value set in the policies (including EPR) will remain effective on the

devices. Make sure to check your data center power capacity before removing the devices to avoid tripping the

breaker, because the policies will be removed at the same time.

1. Go to Add/Remove Programs.

2. Select Dell Power Measurement, Mitigation, and Management, and click Remove.

3. Click Yes to confirm. Follow the on-screen instructions.
