(2)A total of eight base units including one main base unit and seven extension base units can be used. However, the usable slots (number of modules) are limited to 64 per system including empty slots. If a module is installed in slot 65 or subsequent slot, an error (SP. UNIT LAY ERROR) will occur. Make sure all modules are installed in slots 1 to 64. (Even when the total number of slots provided by the main base unit and extension base units exceeds 65 (such as when six
POINT
(1)Q172DLX/Q172DEX/Q173DPX cannot be installed in CPU slot and I/O slot 0 to 2 of the main base unit. Wrong installation might damage the main base unit.
(2)Q172DEX can be installed in the main base unit only. It cannot be used in the extension base unit.
