Power unit cover
Opening the power unit cover
The power unit cover can be opened even if the blade enclosure is powered on. When you install or
remove a power unit, keep the power unit cover open. If you keep using the system, close the
power unit cover.
For information on how to remove a CPU blade and a power unit, see "Installing a CPU blade"
on page 41 and "Power unit" on page 81, respectively.
Make sure to follow the instructions and notes to use the blade enclosure and other
devices safely. There are risks of a burn, injury, or damage to physical assets. For
more information, see the descriptions on page 3.
 Do not use the blade enclosure with its covers and fans removed. If you use the
blade enclosure without them, the cooling efficiency inside the blade enclosure
degrades, causing malfunction. Also, dust may get in and cause a fire or electric
shock.
 Be careful not to hurt your fingers.

cover to unlock it.
