6.1 Precautions When Mounting Disk Array Units in an Unauthorized Rack
This section presents safety precautions when installing disk array units in an unauthorized rack.
These precautions are presented to ensure safety when disk array units are installed in an unauthorized rack.
However, proper operation of the disk array units cannot be guaranteed if they are installed in an unauthorized
rack. For information about authorized racks, contact your sales representative.
6.2 Directions for Safe Mounting
・
When mounting disk array units in a rack, take the installation specifications into consideration so that
ambient environmental conditions can be satisfied while the disk array units are operating.
When installing units in a rack with a door or a rack equipped with multiple units, take the following points
into consideration when the units are operating.
- Take air flow into consideration so that the temperature requirement of the ambient environmental
conditions is not exceeded.
- The temperature inside a rack in which disk array units are operating must not exceed 40 C.
・
A constant volume of air is required for the disk array unit to operate safely.
・
When mounting units in the rack, make sure that no object blocks the air vents at the front and rear of the
disk array unit and that the air vents are not closed.
・
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.
- For the maximum configuration of disk array units, the weight of the M100/M300 disk array controller is
approximately 31 kg, weighty of the M500 disk array controller is approximately 39 kg, weighty of the
M700 disk array controller is approximately 48 kg , and the weight of the disk enclosure is approximately
29kg.
・
Connecting the power cord of a disk array unit to a power strip or the service outlet of another unit may
subject the connected power strip or power cord of the other unit to a high load.
Verify that the total current rating of units including the disk array unit does not exceed the current rating of
the connected power strip or service outlet of the other unit.
・
Always ground a unit that is mounted in a rack.
Be particularly careful if the power cord of the disk array unit is not directly connected to a power distribution
board (such as when using a power strip).
