NOTES ON HANDLING ∼ FOR PROPER OPERATION∼
Observe the following notes for successful operation of the Disk Expansion Unit. Using the Disk
Expansion Unit while ignoring the notes will cause malfunctions or failures of the chassis.
Make sure to power off the Disk Expansion Unit before connecting or disconnecting cables
between the chassis and the NEC Express server.
Check that the Disk Power LED on the Disk Expansion Unit is off before turning off the chassis.
When you turn off the Disk Expansion Unit, wait at least 30 seconds before turning it back on.
Turn off the power and unplug the power cord from the outlet before relocating the Disk
Expansion Unit.
Clean the Disk Expansion Unit on a regular basis. Regular cleaning prevents various failures
of the chassis.
Lightning may cause a momentary voltage drop. To prevent this problem, we recommended
you use an uninterruptible power supply.
Make sure to use optional devices supported by the Disk Expansion Unit. Some
non-supported devices may be physically installed and connected but cause failures of the
chassis as well as malfunctions of the chassis.
NEC recommends you use NEC genuine products. Some third-party products claim they
support the Disk Expansion Unit. However, repair of the chassis due to a failure or damage
resulted from use of such third-party products will be charged even during the warranty period.
