Installing a power unit
Follow the steps below to install a power unit. A power unit can be installed or removed even if the
blade enclosure is powered on. Power units can be removed only in a redundancy configuration. If
you want to remove a power unit in a non-redundancy configuration, power off all devices on the
blade enclosure. Installation can be done in both redundancy and non-redundancy configurations.
An example of installation is provided below. Follow the same steps for installation on other slots.
Make sure to follow the instructions and notes to use the blade enclosure and other
devices safely. There is a risk of death or serious injury. For more information, see
the descriptions on page 3.
 Do not place your hands inside the blade enclosure.
 Do not insert a wire or metal object.
1. Check that the AC inlet corresponding to the slot on where you to install a power unit has a
power cord connected. If not, connect a power cord.
2. If the power unit is installed on the slot 3 or 4, slide the key box so that it will not impair the
installation. For information on moving the key box, see "Moving the key box."
3. If the slot on which you are installing
the power unit has a slot cover,
remove it.
Pull the slot cover hook forward.
Important
● Keep the slot cover that has been removed in a safe place.
● Do not remove any slot covers other than the one attached to the slot where you
wish to install the power unit.
4. Put the power unit on a clean, flat
table and open the power unit ejector.
When you open the power unit ejector,
push the power unit stopper securing
the power unit ejector downward.
