2. Do not install two power supply units with different wattages. Related information is available from the
following:
• Read the label on top cover for maximum wattage output of installed power supply units. Only replace the
existing units with those with the same wattage as marked on the label.
• Check the rear of the node to make sure there is no length difference between the two installed units. If
there is visible difference in length, it means the two units come with different wattages, and one of them
have to be replaced.
