Maintenance Mode

Maintenance mode is automatically launched when the software on the VBrick appliance
does not load. A message on the front panel will indicate the appliance is in Maintenance
mode.

Maintenance mode runs from a reduced functioning kernel that provides limited

access to the appliance via the Command Line Interface only

. You can access the

Command Line Interface via the serial port or Telnet. (see the

H.264 Appliance 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
appliance so you can download new software.

Number of Loops to Run Number of times to run the test.

Intensity

Low intensity is faster but runs fewer tests. High intensity runs
all tests but may take up to 10 minutes.
