Lineage Power Supply Alarms
The Lineage PS modules have two known issues that may produce an
alarm when the power is turned off:
• Removing the power supply and then re-inserting before the power
supply's fans have stopped spinning.
• Cycling the power for short periods of time (approximately less than 10
Sec.) or a brief power failure.
The work around for each of these issues is described below.
Note These steps assume that the system is operational.
Removing the Power Supply and Inserting Too Soon
When a power module is removed:
1. Wait until the module's fans have stopped spinning (approximately 10
sec.).
2. Re-Insert the module.
Cycling the power for short periods of time or a Power Failure
When a power failure lasts between 1 to 10 seconds, the power supply may
come back up in an alarm condition.
To correct the alarm condition, do one of the following:
Extract the power supply module
1. Extract the alarming power supply module.
2. Wait until the module's fans have stopped spinning (approximately 10
sec.).
3. Reinsert the power supply module.
Remove AC power to the System
1. Remove AC power to the system
2. Wait until the power supply module's fans have stopped spinning
(approximately 10 sec.).
3. Reapply the AC power, simultaneously to all power supply modules.
