Lenovo ThinkServer sd350 Installation And Service Manual page 116

1. Make sure the devices you are installing are supported. For a list of supported optional devices for the
server, see http://www.lenovo.com/us/en/ serverproven/.
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's no length difference between the two installed units. If
there's visible difference in length, it means the two units come with different wattages, and one of them
have to be replaced. Also, error message PSU_Mismatch would appear in this case.
Statement 5
CAUTION:
The power control button on the device and the power switch on the power supply do not turn off
the electrical current supplied to the device. The device also might have more than one power
