The voltage may drop momentarily due to lightning. It is recommended to use an
uninterruptible power supply (UPS) to prevent this problem.
● Adding optional power supplies and other electronic parts

may not work properly and may damage the Blade Enclosure.
It is recommended to use genuine NEC products for optional cards. Some optional cards from
