Managing Appliances

The amount of time it takes to complete a software upgrade depends on the appliance model and speed of the link. The upgrade time increases proportionately to the decrease in the link speed. If software is not successfully loaded to any particular appliance in a predefined time frame, the connection times out. The software upgrade timeout is user-configurable (Edit > Preferences > ETEMS > Communications).

Prior to upgrading an appliance, we recommend making a backup copy of the existing file system. If you experience a problem with an upgrade, you can then restore the appliance’s file system from the backup copy. A backup is created automatically on ETEP appliances.

Figure 40 Upgrade remote appliances first when managing appliances in-line, where management traffic flows through the data path

If you are managing your EncrypTight appliances in-line as shown in Figure 40, we recommend performing a software upgrade in two stages. First, upgrade all the appliances at remote sites and reboot them. When the remote site appliances are up and operational, upgrade the local site appliance, which is co-located with the ETEMS management station. Upgrading the local appliance at the same time as the remote appliances can cause connectivity with the management station to be lost and the remote site upgrades to fail.
