Power unit
Additional power units are options that are installed when CPU blades and other modules on the
blade enclosure require more power units or when you want to enable power redundancy functions.
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.
● Air exhausted from power fans may get hot.
Important
● The power unit that can be installed on the blade enclosure is N8405-025F.
● The number of power units required depends on the number of modules, such as CPU blades,
and the power redundancy mode selected. See "Power unit installation guide" and add power
units as necessary. The blade enclosure is equipped with two power units as standard.
