Chapter 1 Hardware Preparation and InstallationFront/Rear Ethernet and Transition Module Options Header (J30)A 40-pin planar header allows for selecting P2 options. Jumpers installed across Row A pins 3-10 and Row B pins 3-10 enable front Ethernet access. Jumpers installed across Row B pins 3-10 and Row C pins 3-10 enable P2 (rear) Gigabit Ethernet. Only when front Ethernet is enabledcan the jumpers be installed across Row C and Row D on pins 1-10 to enable P2 (rear) PMCI/O. Note that all jumpers must be installed across the same two rows (all between Row A andRow B and/or Row C and Row D, or all between Row B and Row C).The following illustration shows jumper setting options for J30. The factory default is shownwhere applicable:J30 Options111213110203040111213110203040111213110203040Front Ethernet(Default)Rear EthernetNon-Specific Transition Module(Default)111213110203040111213110203040111213110203040PMC I/O TO P2(Default)MVME 712MTransition ModuleMVME 761Transition Module4294 0604Refer to Front/Rear Ethernet and Transition Module Options Header (J30) on page 65 forconnector pin assignments.SROM Configuration Switch (S3)A part of the 8-position SMT switch, S3 enables/disables the MV64360 SROM initialization andall I 2 C EEPROM write protection.The SROM Init switch is OFF to disable the MV64360 device initialization via the I 2 C SROM.The switch is ON to enable this sequence.The SROM WP switch is OFF to enable write protection on all I 2 C. The switch is ON to disablethe I 2 C EEPROM write protection.Table 1-3.
