Note
If the rear P2 Ethernet is selected by jumpers J6, J7, J100, and
J101, the Ethernet signals also connect to PMC 1 user I/O
connector J14. If a PMC card is plugged into PMC 1, there may
be a conflict between the I/O from the PMC card and the rear
Ethernet signals. This conflict does not occur with the IPMC761
or IPMC712 modules.
For rear P2 Ethernet, install jumpers on all four headers (J34, J97, J98, and
J99) when in SBC/IPMC761 mode. No jumpers are installed for front-
panel Ethernet.
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
Table 5-21. Ethernet 2 Selection Headers (J34, J97, J98,
J99) Pin Assignments
