Rules for replacing
power supplies
When replacing the power supply in your appliance, observe the following rules:
◆
You do not need to turn off the power to the appliance when you replace one
power supply at a time.
◆
If you are replacing both power supplies, replace them one at a time to avoid
powering down your appliance.
◆
Although a single fan failure in one of the power supplies is not a critical
event, it is recommended that you install a new power supply when one of
the two fans in either power supply stops working.
◆
When hot-swapping power supplies, replace and install the power supplies
within two minutes of each other.
Caution
Your appliance can run with one power supply for a maximum of two
minutes. The airflow through your appliance is degraded when only one
power supply is present and operating. Therefore, if the power supplies are
not replaced within two minutes of each other, the system halts and no data
is accessible.
◆
Have the replacement power supply close by and ready to install before
removing the old one.
