VBrick 9000 Encoder Admin Guide
Description
This mode is launched when the software loads but encounters
other errors. When some error conditions occur, for example a high
temperature alarm, the encoder will automatically go into Limited
Run Mode. When this happens a message will display on the
encoder front panel and a Limited Run Mode status will display on
the Monitor > Monitor the System page in VBAdmin. In Limited
Run Mode, you can make configuration changes with VBAdmin,
reboot the encoder, or perform other admin tasks to resolve the
problem. The only thing you cannot do in Limited Run Mode is
stream video. When the error condition(s) that initiated Limited
Run Mode have been resolved, manually reboot the encoder. It will
come up in normal Run Mode and you can resume streaming.
This mode is required to run Device Tests and to check the hard
drive and file system on internal and external storage devices.
Maintenance mode is automatically launched when the software on
the VBrick encoder does not load. A message on the front panel
will indicate the encoder is in Maintenance mode. Maintenance
mode runs from a reduced functioning kernel that provides
limited access to the encoder via the Command Line Interface
only. You can access the Command Line Interface via the serial
port or Telnet—but not via SSH. (See the Encoder Getting Started
Guide for more about the Command Line Interface.) As shown
below, Maintenance mode has limited configuration and diagnostic
capabilities. It enables the FTP server on the encoder so you can
download new software.
This mode is used to prevent the user from being locked out of
VBAdmin when CPU utilization approaches 100% (as shown on
the Monitor > Monitor the System page). If this happens, certain
management tasks (for example, running VBAdmin) are given
priority over streaming. Overloaded Mode will transition to Run
Mode when CPU utilization is reduced. This mode occurs when the
encoder is configured to handle more video than its operational
capacity. If this occurs, the encoder needs to be reconfigured to
reduce the number of streams and/or data rates. For more details
see below Avoiding Overload Conditions.
