Controller Display Messages
Each array controller in an MSA1000 contains an integrated display. This module
is used for displaying informational and error messages, showing the current
status of the module, and for providing user input when required. Traditional
Power-On-Self-Test (POST) messages issued by PCI-based array controllers have
been combined with runtime event notification messages to create a new set of
controller display messages.
The display module consists of the following components:
■ A two-line, twenty-column display text display window
■ Four push buttons arranged in a circular “pie” shape
■ Two status indicator lights
