Hint
About maintenance services
Diagnostic and maintenance services by personnel with expertise on maintenance of
the blade enclosure are available.
● Blade enclosure
- Use a rack that allows installation of the blade enclosure.
- This product must be installed in a restricted access location.
- Make sure to install or remove parts, such as fan units, correctly when a module is installed
or removed.
- Remove the dust on the exterior and fans located at the front and rear of the blade enclosure
regularly. Regular cleaning prevents various failures from occurring.
- The voltage may drop momentarily due to lightning. It is recommended to use a device such
as an uninterruptible power supply system to prevent this problem.
● Adding optional power supplies and other electronic parts
- These products are made of very static-sensitive parts. Eliminate static electricity before
handling the products. Do not touch plug terminals or parts with your hands. Do not place
the products directly on a desk.
- Do no use any optional devices other than those shipped with the blade enclosure or
specified by NEC. Even if such optional devices can be installed on or connected to the
blade enclosure, they may not work properly or can damage the blade enclosure.
- It is recommended to use genuine NEC products for optional devices. Some optional
devices from other manufacturers are supported in the blade enclosure. However, services
for repairing malfunctions or damage caused by them are provided at your expense, even in
the warranty period.
