Hot-swapping controller power supplies
Hot-swapping controller power supplies
Power supply units (PSUs) in a AltaVault system are auto-ranging, redundant, hot-swappable field- replaceable units
(FRUs). You can hot-swap the power supplies on a controller while the system is powered on without disrupting the
normal operation of the system.
Note:
When a power supply fails, an alarm is raised. The UI shows a degraded state with the appropriate alarm information, and if
configured, an email is sent to the administrator.
Before you begin
If you are replacing more than one power supply on a controller, you must do so one at a time to prevent system
downtime.
If you must remove all power supplies, leaving the controller without any power, you must first shut down and
then power off the system using the steps described in the procedure,
“Shutting down controllers” on page 60
.
Removing power supplies
This section describes how to remove a power supply.
Note:
Replace a failed power supply promptly to minimize disruption to the controller's airflow. The system continues to function
normally, but the AltaVault OS logs alert messages in the event log file about the degraded power supply until the power supply is
replaced.
To remove a power supply
1.
Identify the power supply you want to replace, based on the event log messages or through the amber fault LED
on the power supply.
2.
If
you
are not already grounded, properly
ground yourself
.
3.
Turn off the target power supply by turning the on/off switch to the OFF (O) position. If the power source for this
power supply has a on/off switch, turn the switch to the OFF (O) position.
4.
Remove the power cord from the power supply, using the image below as a reference.
Pinch the tab on the locking mechanism of the power cord retainer clip, and open the retainer clip.
Slide the retainer clip off the cord.
Unplug the power cord from the power supply and the power source.
5.
Press down the release latch on the power supply cam handle to unseat the power supply.
