Press any button on the front panel display to silence the alarm. If the alarm status changes, the alarm beeps
again, overriding the previous alarm silencing.
Possible Cause
The bypass utility became unavailable
during the test.
User cancelled the battery test through the
front panel.
The bypass utility does not qualify.
Bypass mode is disabled.
The UPS is not recognizing another
paralleled UPS.
The system is not configured as parallel.
The UPS detects an internal fault.
The specified power rating of the parallel
system has been exceeded.
Parallel-Ready System only. Parallel
Operation mode is set to "Redundant
Mode."
The UPS failed to identify itself as a
paralleled UPS within two minutes after
utility power was applied.
The UPS detects a paralleled UPS with a
later firmware version.
During parallel system startup, the UPS
detects a UPS in the system with a different
OEM number.

Service and Troubleshooting
Action
Verify that the bypass utility is available and within limits. Restart the
battery test. If the battery test aborts repeatedly, see "Running
Automatic Battery Tests" on page 105.
Restart the battery test.
Check the bypass utility. The UPS is receiving bypass utility power
that may be unstable or in brownout conditions.
Check that the bypass user settings are configured appropriately (see
"User Settings" on page 95).
From the UPS Status menu, select the Units on CAN Bus option and
verify that all UPSs appear in the list.
If any UPS is missing, verify the Powerware Hot Sync CAN Bridge
Card connections and recheck the status from the UPS front panel.
If all UPSs appear in the list, check the redundant signal wiring (see
Figure 64 on page 79).
Set the system to internal Bypass mode.
If the condition persists, contact your service representative.
Verify the CAN wiring (see Figure 63 on page 78).
Verify that the line cord is installed properly.
Shut down the UPS where the alarm is indicated.
Start up the UPS.
Select the Turn System On option through the front panel of the UPS
that was turned off.
If the condition persists, contact your service representative.
The load is supported, but the system lacks redundant protection
while the overload persists. Remove some of the protected
equipment.
BladeUPS parallel systems are defaulted to "Redundant Mode." For a
parallel-ready system (a single UPS installed to be part of a future
parallel system) set the Parallel Operation Settings / Parallel
Operation Mode to "Capacity Mode" to prevent unnecessary alarms.
Verify the CAN wiring (Figure 63 on page 78).
If the condition persists, contact your service representative.
Mixing major firmware versions is not supported. For minor firmware
versions, the alarm does not prevent operation, but different
firmware versions in a parallel system cause conflicts.
Verify that all UPSs in the parallel system have the same firmware
version. For updates, see"Updating the UPS Firmware" on page 129
Verify that all UPSs in the parallel system are from the same
manufacturer. UPSs with different OEM numbers will not parallel.
