7.7.2 Mounting and demounting card PCBs
CAUTION1 The base printed–circuit board must be removed before the
PCB card can be dismounted and mounted. Observe the CAU-
TIONS in Subsection 7.7.1.
CAUTION2 Be careful not install the PCB card in an incorrect location.
Otherwise, the printed–circuit board may be damaged.
CAUTION3 The boot software is stored in the FROM on the CPU card.
When replacing the CPU card, make sure that the function
stored on the replacement CPU card is of the same version as
before or of a later version. Otherwise, it may be inoperable.
(The version of the system software has nothing to do with the
general version of the printed–circuit board.)
CAUTION4 The installed boot software varies depending on the type of the
CPU card. When replacing the CPU card, make sure that the
replacement CPU card is also a Power Mate i CPU card. Note
that the 16i/18i/21i CPU card cannot be used in place of the
Power Mate i CPU card.
D Demounting a card PCB
1) Dismount the base printed–circuit board by following the
dismounting procedure described in Subsection 7.7.1.
2) Pull outward the claw of each of the four spacers used to secure
the card PCB, then release each latch.
3) Extract the card PCB upward.
D Mounting a card PCB
1) Check that the claw of each of the four spacers is latched outward,
then insert the card PCB into the connector.
2) Push the claw of each spacer downward to secure the card PCB.
3) Mount the base printed–circuit board by following the mounting
procedure described in Subsection 7.7.1.
