Means Of Preventing Rack From Tipping Over; Rack Mounting Rules - NEC M100 Installation Manual

5.2 Means of Preventing Rack from Tipping Over

・ Fasten the rack to the floor.
Use an appropriate method of fastening the rack to the floor so that mounting disk array units in the rack
does not cause the entire rack to become unstable.
- Be careful not to injure yourself when mounting disk array units in the rack.
- Do not mount disk array units in a rack that would become physically unstable.
- The weight of the disk array controller for the maximum configuration M100/M300 (Disk array controller +
Accessory) is approximately 34 kg, M500 (Disk array controller + Accessory) is approximately 42 kg, and
M700 (Disk array controller + Accessory) is approximately 51 kg.
・ If an appropriate method cannot be found to fasten the rack to the floor, attach a stabilizer.
Someone might be injured if vibration caused the rack to tip over.

5.3 Rack Mounting Rules

・ To prevent the entire rack from becoming unstable when disk array units are mounted in the rack, mount
heavier units at the bottom and lighter units at the top.
・ If a rack in which disk array units are mounted has an empty area where no units are installed, attach a
closing plate (blank panel) to prevent a breeze from circulating within the rack.
- There is a risk that air circulating in the rack may prevent the ambient environmental conditions of the
disk array unit specifications from being satisfied.
