NOTE: 1. The SX-200 LIGHT system must be equipped with the Switch Matrix Module
instead of the DX Module used in the 336, 456 & 480-port systems or the
Switch Matrix Card used in the 672 -port system.
2. A normal running system may show other codes (card diagnostics or errors).
However, during start-up, only the codes in this table are possible. Any other
code shown during start-up indicates a faulty Main Control Card.
3. Codes possible AFTER start-up include card diagnostics codes (last card lo-
cation tested, top number indicates bay number, bottom number indicates
card slot number - maintenance logs give results of test, i.e., pass or fail with
cause), or disk error codes.
