5.3.1.2PMC/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:

Table 5-22 PMC/SBC Mode Selection Headers (J28, J32) Pin Assignments

J28		J32
Pin	Signal	Pin	Signal
1	Fused –12.0V	1	Fused +12.0V
2	P2_PMC1_IO (60)	2	P2_PMC1_IO (13)
3	PMC1_IO(60)	3	PMC1_IO(13)

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.
