Table 1-2 MVME5500 Jumper Settings 

The MVME5500 is factory tested and shipped with the configuration described in the following 

section.

1.6.2 Ethernet 2, PMC/SBC Mode, and P2 I/O Selection Headers (J6, 

J7, J28, J32, J34, J97 – J110)

All of the headers described below are used in conjunction with each other to select various 

modes of operation for 10/100BaseT Ethernet, PMC/SBC mode, and P2 I/O mode.

1.6.2.1 Ethernet

Four 3-pin planar headers (J6, J7, J100, J101) and four 2-pin planar headers (J34, J97, J98, 

J99) are for 10/100/BaseT Ethernet 2 selection.

Ethernet 1 is the Gigabit Ethernet port and is front panel only.

Figure 1-1 MVME5500 Board Layout

For J6, J100, J7 and J101, install jumpers across pins 2-3 on all four headers for rear P2 Ethernet. For front-panel Ethernet, install jumpers across pins 1-2 on all four headers. For J34, J97, J98 and J99, no jumpers are installed for front-panel Ethernet. For rear P2 Ethernet, install jumpers across pins 1-2 on all four headers when in SBC/IPMC761 mode. 1.6.2.2 PMC/SBC Mode Selection The MVME5500 is set at the factory for PMC mode. The SBC/IPMC761 mode should only be selected when using the IPMC761 module in conjunction with the MVME761 transition module.The PMC mode should be selected when using PMC modules with specific user I/O in conjunction with the corresponding transition module. PMC mode should also be selected when using PrPMC modules. Two 3-pin planar headers (J28, J32) control the supply of +/- 12 volts to the P2 connector; one or both of these voltages are required by the MVME712 or MVME761 module when operating in SBC mode. For PMC mode, jumpers are installed 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. 1.6.2.3 P2 I/O Selection Nine 3-pin planar headers (J102 –J110) are for P2 I/O selection. Jumpers are installed across pins 1-2 on all nine headers when in PMC mode. Install jumpers across pins 2-3 on all nine headers when in SBC/IPMC761 or SBC/IPMC712 mode to connect the extended SCSI signals to P2. 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 slot 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. Product Damage 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. 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.

Flash Boot Bank Select Header (J8)

A 3-pin planar header selects the boot Flash bank. No jumper or a jumper installed across pins 

1-2 selects Flash 0 as the boot bank. A jumper installed across pins 2-3 selects Flash 1 as the 

boot bank

Flash 0 Programming Enable Switch (S3-1)

This switch enables/disables programming of Flash 0 as a means of protecting the contents 

from being corrupted. The switch set to OFF disables all Flash 0 programming. The switch set 

to ON enables the programming, this is the factory setting.

 Safe Start ENV Switch (S5-1)

This switch selects programmed or safe start ENV settings. When set to OFF, it indicates that 

the programmed ENV settings should be used during boot. Set to ON indicates that the safe 

ENV settings should be used.
