Abstract
By use of a GUI (Graphical User Interface) or CLI (Command Line Interface) a user can issue a command to configure an external SAS Port as table routing mode or subtractive mode. The SAS switch receives and decodes the command. Subsequently, the SM asserts the appropriate indicator behavior for the port being addressed.
Claims8
A method to manage external indicators for different SAS port types, said method comprising:
- allowing a user to issue a command to a SAS switch module, said SAS switch module having a plurality of physical interface ports, each of said plurality of physical interface ports having an attribute type, an indicator, and an operating mode, said operating mode being either a table route mode, or a subtractive mode;
- checking, by way of said SAS switch module, said attribute type of each of said plurality of physical interface ports;
- programming, by way of said SAS switch module, each of said indicators associated with each of said plurality of physical interface ports to flash at one hertz rate when said operating mode is said table routing mode and at two hertz or faster rate when said operating mode is said subtractive mode;
- and
- allowing said user to visually confirm said attribute type of each of said plurality of physical interface ports by inspection of each of said indicator associated with each of said plurality of physical interface ports.
