9. Reinstall the MVME5100 assembly in its proper card slot. Be sure the host board is well
seated in the backplane connectors. Do not damage or bend connector pins.
10. Replace the chassis or system cover(s), reconnect the system to the AC or DC power
source, and turn the equipment power on.
5.5 RAM500 Connectors
RAM500 memory expansion modules are populated with one or two connectors. If the
module is to be used in tandum with a second RAM500 module, the “bottom” module will
have two connectors: one to mate with the MVME5100 host board (P1), and one to mate with
the “top” RAM500 module (J1). The “top” RAM500 module has only one connector, since it
needs to mate only with the RAM500 module directly underneath it and because an added
connector on a tandum RAM500 configuration would exceed the height limitations in some
backplanes. If only one RAM500 module is being used, a top module, single connector
configuration is used.
A 4H plug and receptacle are used on both boards to provide a 4 millimeter stacking height
between dual RAM500 cards and the host board.
The following subsections specify the pin assignments for the connectors on the RAM500.
5.5.1 Bottom Side Memory Expansion Connector (P1)
The bottom side connector on the RAM500 is a 140-pin AMP 0.6mm Free Height mating plug.
This plug includes common ground contacts that mate with standard AMP receptacle
assemblies or AMP GIGA assemblies with ground plates. A single memory expansion module
will have 1 bank of SDRAM for a maximum of 5Mbytes of memory. Attaching a second memory
module to the first module will provide 2 banks of SDRAM with a maximum of 1Gigabytes
