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 sys-
tems or the Switch Matrix Card used in the 672 -port system.
2. A normal running system may show other codes (card diagnostics or er-
rors). 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 location 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.
