SRAM Battery Backup Source Select Header (J20)
2
The MVME162 is factory-configured to use VMEbus +5V Standby power as a
backup power source for the SRAM (i.e., jumpers are installed across pins 1
and 3 and 2 and 4). To select the onboard battery as the backup power source,
install the jumpers across pins 3 and 5 and 4 and 6.
N ote
For MVME162s without optional VMEbus interface (i.e.,
without VMEchip2 ASIC), you must select the onboard
battery for the backup power source.
C aution
Removing all jumpers may temporarily disable the SRAM.
Do not remove all jumpers from J20, except for storage

EPROM Size Select Header (J21)
The MVME162 is factory-configured for a 4Mbit EPROM (i.e., a jumper is
installed across pins 2 and 3). This is the only size currently available; if a
larger PROM becomes available, this jumper will allow it to be selected.
