Installing Printed Circuit Cards
IPM BOARD
This board has a switch S1 for memory back up and installs in position LOC2
(see Figure 3-1)
of the
MCP card when the system has more than one cabinet installed or the system is going to require the L
version software in a single cabinet. The IPM board is required to expand the system memory and to
provide the message handling processor so the MCP can communicate with the SCP and LCP(s). To
install the IPM board remove the two (2) screws holding the MCP protective casing together
(see Figure
3-6)
and separate the two halves of the case. Place the IPM board face down over the three connectors,
taking care to properly line them up and press gently on the back of the board to seat it. The MCP
case can now be reassembled if all required daughter boards have been installed.
NOTE:
Do not forget to turn on the memory backup switch on the IPM board before installing it on the
MCP
(See Figures 3-1 and 3-7)
