• Set ENB/DIS faceplate switches on the CMA and CPU FN circuit
packs to ENB and invoke a SYSLOAD by pressing the RESET or
RS button on the CMA circuit pack on the QSD61 shelf.
16 Refer to 553-3001-400 for an interpretation of codes displayed on the
faceplate of the MSI circuit pack. Some of the normal codes which
may appear during SYSLOAD are;
• A1 – when records are being read from disk.
• 00 – when the MSI power-up is completed.
• 10 – when the MSI is in an idle state.
