1. If any I/O boards are fitted these will need to be removed to gain access to the
CPU board. Refer to later in this section for removal procedure.
2. Unscrew the four short pillars (or long + short mounting pillars if an I/O board was
fitted) shown in Figure 20 below.

back
of the board clear of the rear mounting studs and slide the board back
to clear the front connectors from the front panel then lift the board vertically off the
front studs as shown in Figure 21 below.

board will slide off.

rear of the board raised above the rear mounting pillars.

then drop the rear of the board onto the rear mounting pillars.
