5.3.1.2 PMC/SBC Mode Selection
Two 3-pin planar headers on the MVME5500 are for PMC/SBC mode selection. For PMC
mode, install jumpers across pins 1-2 on both headers. For SBC/IPMC761 mode, install
jumpers across pins 2-3 on both headers. For SBC/IPMC712 mode, install a jumper across pins
2-3 for J32 and install a jumper across pins 1-2 for J28. Selection notes follow the table. The
pin assignments for these headers are as follows:
1. When J28 is configured for SBC/IPMC mode, –12V is supplied to P2 pin A30. If there is an
incompatible board plugged into this P2 slot, damage may occur.
2. When J32 is configured for SBC/IPMC mode, +12V is supplied to P2 pin C7. If there is an
incompatible board plugged into this P2 slot, damage may occur.
3. Install jumpers across pins 1-2 on both headers to select PMC mode. Install jumpers across
pins 2-3 on both headers to select SBC/IPMC761 mode. Install a jumper across pins 2-3
on J32 and install a jumper across pins 1-2 on J28 to select SBC/IPMC712 mode.
