Power supply units (PSUs)
— These two removable power supplies operate in a
redundant configuration. They are hot-swappable — if one fails, it can be replaced
while the processor is operating (see
Replacing a power supply (Quantum
on page 58). Each PSU has a Power rocker switch that powers the
PSU on and off. It is not necessary to turn these switches to Off when you power off
the processor.
ATTENTION:
•
Both
power supplies must be powered on at all times during operation of the
processor.
•
If a power supply fails, replace it as soon as possible.
•
Les deux alimentations doivent être allumées en permanence pendant
l’utilisation du processeur.
•
Si l’une des alimentations tombe en panne, remplacez-la dans les plus brefs
délais.
