Testing Powerfail Recovery (990/992/890 Systems
without a UPS)
NOTE
This section applies only to 990/992/890 Systems without a
Uninterruptible Power System (UPS).
After the operating system has been installed, the following test can be performed to
determine if system powerfail recovery and memory battery backup are functioning
correctly.
CAUTION
Minimum memory for 990/992/890 Systems without a UPS
For powerfail recovery to function properly on these systems, a minimum
amount of memory must be installed in the system:
■
990/992/890 Systems with one or two processors: 128MB of memory
■
890 Systems with three processors: 192MB of memory
■
890 Systems with four processors: 256MB of memory
■
990/992 Systems with three or four processors: 256MB of memory
Failure to meet the minimum memory requirements will result in lost
data during a powerfail recovery.
Powerfail recovery occurs when primary AC power is restored before the memory battery
backup fails. The system therefore resumes with fully valid memory. This test checks the
ability of the system (after the operating system has been installed) to perform a powerfail
recovery, and also checks the memory backup battery.
Proceed as follows:
1. Turn on system, booting normally (autoboot flag set ON!). Make sure one or more
applications are active, so that memory swapping is active. Also verify that the BATT
CHG LED is off.
2. Turn off the power switch (circuit breaker) on the lower rear of the cabinet, wait five
minutes, then switch power back on.
NOTE
Do NOT turn the "Standby-Ready" switch on the front panel to the
"Standby" position; this disconnects the battery and disables powerfail
recovery.
3. Observe reboot and action of application.
If the system performs normally, powerfail recovery is working properly, and the memory
battery backup is good.
