Cisco Energy Management - Version 5.2.0

Date: 07/07/2016

System and Installation Requirements

Cisco Energy Management Version 5.2.0 can be used for single instance installations as well as for distributed deployments, using an Cisco Energy Management Server and multiple Cisco Energy Management Controllers.

Single Server Deployment

Minimum Recommended 5,000 Devices 10,000 - 25,000 Devices
CPU Dual Core, 2GHz Dual Core, 2GHz 2 Quad CPUs
RAM 4 GB 8 GB 16 GB
Hard Disk 1) 40 GB 250 GB 500 GB
Operating System Windows 7 (64-Bit) Win Server 2008 R2 (64-Bit) Win Server 2008 R2 (64-Bit)

Large Scale Multi Server Deployment

For deployments with more than 25,000 devices we recommend the use of a dedicated central server with requirements as follows:
50,000 - 100,000 Devices 100,000 - 200,000 Devices
Deployment component Cisco Energy Management Server Cisco Energy Management Server
CPU 2 Quad Core CPUs 2 Quad Core CPUs
RAM >24 GB >32 GB
Hard Disk 1) 1 TB 2 TB
Operating System Windows Server 2008 R2 (64-Bit) Windows Server 2008 R2 (64-Bit)

In addition to the central server, several controllers might be required – with a maximum of 25,000 devices per controller with specifications as follows:

up to 25,000 Devices
Deployment component Cisco Energy Management Controller
CPU Quad Core, 2GHz
RAM 4 GB
Hard Disk 1) 50 GB
Operating System Windows 7 or Server (64-Bit)
CentOS 6.5 (x86/x64)
1) Hard disk performance plays a critical role in the deployment. Cisco Energy Management ships with its own database to store device data, power measurements and other data at a high rate. A local physical storage or high-performance SAN is recommended, especially when deploying on a VM.

Note: A single Cisco Energy Management Controller is designed to handle a maximum total of 25,000 devices.

Cisco Energy Management has a browser-based management console for configuration, operation, and reporting. For the best user experience, it is recommended that you use an up-to-date browser, such as the latest version of Google Chrome (preferred), Mozilla Firefox or Internet Explorer 11 or better. Older browsers, especially IE 6, are not fully supported. Regardless of which browser is used, JavaScript will need to be enabled.

The Controller uses Microsoft .NET 4.0 framework. If this framework is not present on the server prior to installation, it will be automatically downloaded and installed as part of the Controller installation. If the internet connection on the installation server is slow or unavailable, we recommend that you manually download and install the Microsoft .NET 4.0 framework prior to beginning the Controller installation (Download here: http://msdn.microsoft.com/en-us/netframework/).

Updating/patching existing installations

  1. Get the latest CEM Update

    For CEM Server updates as well as CEM Controller updates, the same update file is used. Files are available at Cisco Energy Management Download Page

  2. Updating Order
  3. When executing the update file, the setup wizard will guide you through the update process.

    Important: If your CEM server installation runs separately from your CEM Controller installation(s), please make sure to first apply the update to the CEM server installation. During the CEM server update a keypair file will be created which later is required to update the separately hosted CEM Controllers.

    When updating a CEM standalone-installation (CEM Server and CEM Controller hosted on the same machine), this keypair file is created automatically and can be found at the same directory as the CEM Installation. E.g. C:\Program Files (x86)\Cisco Energy Management Controller\service\cem_keypair.key.

  4. Verify that the update process has succeeded
  5. The update process was successful if all services are up and running and the CEM User Interface is working properly. Note that there will be a new Service called Cisco Energy Management Controller Watcher solely responsible for Cisco Energy Management Controller.

Known Issues during the update

In rare cases it could happen that the update process will not succeed for very large CEM deployments due to a timeout problem during the data base migration. Please follow these steps to verify you are affected of this issue and how to solve it:
