SCSI Terminator Enable Header (J12)
The MVME162LX provides terminators for the SCSI bus. The SCSI
terminators are enabled/disabled by a jumper on header J12. The
SCSI terminators may be configured as follows.
Note If the MVME162LX is to be used at one end of the SCSI
bus, the SCSI bus terminators must be enabled.
SRAM Backup Power Source Select Header (J14)
Header J14 determines the source for onboard static RAM backup
power on the MVME162LX.
The following backup power configurations are available for
onboard SRAM through header J14. In the factory configuration,
the VMEbus +5V standby voltage serves as primary and secondary
power source (the onboard battery is disconnected).
Note For MVME162LXs without the optional VMEbus
interface (i.e., without the VMEchip2 ASIC), you must
select the onboard battery as the backup power source.
