SRAM Backup Power Source Select Headers (J13, J1)
Jumper header J13 determines the source for onboard static RAM backup
power on the controller’s PCB. Header J1 determines the source for
backup power on the 2MB SRAM mezzanine board (if installed).
The following backup power configurations are available for onboard
SRAM through header J13. In the factory configuration, the 5V
standby voltage serves as primary and secondary power source (the
onboard battery is disconnected).
Notes
For controllers without the optional VMEbus interface
(without the VMEchip2 ASIC), you must select the onboard
battery as the backup power source.
!
Caution
Removing all jumpers may temporarily disable the
SRAM. Do not remove all jumpers from J13, except for
storage.
