9.3 External Battery Input (+5VSTDBY)
Pin +5VSTDBY located at the VME connector P1 pin B31 can optionally supply
current to the RTC and the IPMI controller while the XVR16 is in non-operating
mode.
Without battery and without this +5VSTDBY supply voltage, the Real Time Clock
oscillator must be started at each power up. The duration increases when
operating at lower temperatures and can be up to around 30 seconds (at -40 °C).
This delay is below one second at normal ambient temperatures.
When ordering a battery-less XVR16, the setup information is stored
automatically within an onboard EEPROM and is updated via the standard UEFI
Firmware Setup function. It is recommended to use an external supply voltage to
this battery input to avoid the power-on oscillator start time and to preserve the
date and time information.
The op5VSTDBY also supplies the IPMI controller while the XVR16 is in
non-operating mode. See the following Table for +5VSTDBY current
consumption.
