Software vulnerabilities fixed in DCE 8.3.0

This release includes various component updates to improve overall security.

See the Data Center Expert Security section in the Help Center for more information.

Issues fixed

The following issues were fixed in DCE 8.3.0:

• Improved performance when multiple systems are integrated with DCE.
• Available firmware updates are downloaded as expected from the Updates > Apply Firmware Updates > Check Updates option.
• Available device firmware is now displayed as expected after the firmware update catalog is manually uploaded.
• NetBotz appliances on the private LAN can now send email through DCE.
• Network traffic is now routed from the private LAN to the public LAN as expected.

Known issues

• Only local users or individual AD/LDAP users have access to create or edit dashboards in the web client. Create and edit options are not available for users who are only part of a remote AD/LDAP group. This will be addressed in a future release. 

• When HTTP is enabled without enabling HSTS on the DCE server, the login page for the web user interface is available. Login is not allowed.
  No error is displayed; this will be addressed in a future release.

  If HTTP is not needed, you can modify HTTP and HTTPS settings in the desktop client on the System > Server Administration Settings > Server Access > Web Server tab.

Software update procedure

IMPORTANT - ADDITIONAL STEP REQUIRED

The update from 8.2.0 to 8.3.0 requires that you install a new certificate before you install the software update.

The following steps are necessary to update DCE 8.2.0 to DCE 8.3.0.

DCE must be at a minimum of 8.2.0 to update to DCE 8.3.0. If you are downloading DCE 8.3.0, you will need access to the Internet. 

You must have a valid software support contract to receive the DCE 8.3.0 update.  If you do not, then you will need to purchase one to receive the update.

The DCE software update files are available in the EcoStruxure IT Entitlements portal.Log in and then click Software Updates. More information...

If the DCE update files are not available in EcoStruxure IT Entitlements, contact your local technical support to verify your support contract and get access to the update file(s) you need.

IMPORTANT: Do not reboot the server during the update.

The DCE 8.3.0 update performs a data migration that takes under an hour for most systems. The data migration can take longer if the system has thousands of devices and years of history, and varies based on several factors:

• Number of devices

• Number of sensors connected to those devices

• Polling interval

• Frequency at which sensor values change. For example, input voltage to UPSs can fluctuate throughout the day vs. temperature sensors in a strictly controlled environment that almost always report the same value.

You can see the status of the update on the Data Center Expert web client Home page.

NOTICE: Before beginning an update, remember to run a full backup on your DCE by going to System > Server Administration Settings > Server Backup/Restore, create a backup entry and then click Start.

It is recommended that you perform the server update when you upload the upgrade file to your DCE server. The update will be performed automatically if the server reboots after the upgrade file is uploaded.

1. Download and install the required certificate.

   The certificate is available to download from the 8.3.0 upgrade link in the EcoStruxure IT Entitlements portal.
   Log in to your Data Center Expert 8.2.0 server with full server access.
   Select System > Server Administration Settings > Server SSL Certificates. Click Add to install the certificate.

2. Download the upgrade.zip file, or contact Technical Support for assistance.
   Note: The restore.iso file may be needed for later use if a re-installation is required. See Restoring using ISO Format for instructions for restoring your data from a restore.iso file from the ISO format.
3. Log in to your DCE 8.2.0 server with full server access. Select Updates > Apply Server Update.
4. Click Import to import the upgrade.zip file.
   Note: DCE 8.0 and newer only accept the zipped upgrade file.
5. The Upgrade/New Packages table will update indicating there is an update available for the DCE server. Check the "Install/Upgrade" option for the package(s) you want to upgrade.
   Click the Install Selected button to start the upgrade for the selected package(s). You will be prompted to confirm you want to proceed with the update.
   Click Install Update to start the update process. Do not reboot the server during the update process.
6. When the file transfer completes, DCE will restart and disconnect your console connection. You can point a web browser to the DCE server for status.
7. When the update is complete, point a web browser to the DCE server, and select Download Client.

Restoring Data Center Expert using ISO Format

Warning: Only perform the steps in this section if directed to do so by a Technical Support technician.

Before You Restore:  A system restore will erase all data and restore the DCE hardware server to its factory default settings. Make sure you have a copy of all installed license keys and network settings prior to restore.

1. Download the restore.iso file to create a bootable USB key, or contact Technical Support for assistance.

   For a USB Key, follow the instructions provided in Creating a bootable USB key (Windows or Linux machine).

2. Place the USB key in the USB port of your DCE appliance.

3. Reboot DCE.

4. When the appliance restarts the system restore process begins automatically. This process takes approximately 10 minutes for the 1U DCE Basic, 15 minutes for 1U DCE Standard or 25 minutes for 2U DCE Enterprise.
   When the restore is complete, you will be prompted to remove the USB key and hit enter to reboot the server.
   Note: If the system boots into the existing DCE version, reboot the server and access the BIOS settings. Adjust the boot sequence to boot from USB first.

5. Once DCE has restarted, configure the DCE network settings.

Migrating a Data Center Expert hardware server to a virtual appliance

Before You Migrate: To migrate a DCE hardware server to a virtual appliance, you must purchase and apply an activation key.  Additionally, you must contact APC Support for new node license keys and application license keys for the virtual appliance.

1. Perform a back up of the DCE hardware server, using the Server Backup/Restore option, accessed from the Server Administration Settings option in the System menu.

2. Deploy the demo version OVA, and configure it using the hardware equivalents for the DCE Basic, Standard, or Enterprise server from which you are migrating. The available disk space for the virtual appliance must be greater than the disk space used by the hardware server. You cannot restore to a virtual appliance with fewer CPU, fewer network adapters, less RAM, or less available disk space than the hardware server. See help for Deploying and configuring a DCE virtual appliance, and DCE virtual appliance equivalent configurations.

3. Perform a restore on the virtual appliance, using the Server Backup/Restore option, accessed from the Server Administration Settings option in the System menu. You cannot restore to a virtual machine other than the DCE virtual appliance.

4. Apply the activation key to the virtual appliance.

5. Log in to the DCE client. In the "License Keys" display, accessed from the Server Administration Settings option in the System menu, apply the new node license keys and application license keys you received from APC Support.
