Note 1: Set the groove on the switch knob to the desired switch position.

Note 2: Since DAIA card acts like an FP, the SW1 for DAIA in FPs cannot be set to the same number.

Note 3: When power is on, flip MB switch to ON (UP position) before plugging/unplugging the circuit card.

Note 4: When the clock signal from a master office is supplied via the line between the Main Site and the Remote Site, set the SW1-1 and SW1-2 according to settings in Table 3-3.In this case, DAIA cards (DAIA0, DAIA1) must be mounted in PIM0.
