(Device)
Since the maximum weight of an expansion rack may be about 960 kg when
■
packed and 780 kg when unpacked, confirm in advance that the access route has
no problem with that weight.
Example) Floor conditions on the access route
Confirm that the load capacity is appropriate and casters will neither sink into the
floor nor get caught on the floor.
To bring in the device to an upper or lower floor of a building, confirm that an
■
elevator can be used. Also confirm that the maximum load weight of the elevator
bringing in the device is greater than the device weight.
When pushing the rack to bring in the device, push the lower half of the rack to
■
prevent it from toppling over. The rack may have a higher center of gravity
depending on the devices mounted in the rack.
Also, do not push the rack from the side. Otherwise, it may topple over.
If you push on the area around the center of the front door or the air intake part,
■
the door may be deformed. Instead, push on the corners of the door.
Moving the rack-mounted server product from a cold place into a warm room
■
causes condensation to form inside the product.
Prevent condensation from occurring by adjusting the ambient temperature so
that the temperature rise per hour does not exceed 15°C (59°F). For details
regarding when condensation occurs, see the following table.
