Physical installation safety rules
Power and electrical safety rules
Management safety rules
Before installing the disk shelf, make sure that you have read and understand these physical
installation safety rules.
•
The rack construction must be capable of supporting the total weight of the installed enclosures
and the design should incorporate stabilizing features to prevent the rack from tipping or being
pushed over during installation or in normal use.
•
When installing disk shelves and a storage system into a movable cabinet or rack, install from
the bottom up for best stability.
•
A fully loaded disk shelf is heavy. Do not try to lift it by yourself.
Before moving the enclosure, you can remove all Power Supply Units (PSUs) and I/O Modules
(IOMs) to minimize weight.
◦
A fully loaded DS4243 or DS4246 disk shelf can weigh approximately 110 lbs. (50 kg).
◦
A fully loaded DS2246 disk shelf can weigh approximately 49 lbs (22 kg).
◦
A fully loaded DS4486 disk shelf can weigh approximately150 lbs (68 kg). With only the
two IOMs, four PSUs, and four disk carriers installed, the disk shelf can weigh
approximately 82 lbs (37 kg).
•
A safe lifting height is 20U.
•
Do not lift the enclosure by the handles on the PSUs.
They are not designed to take the weight.
•
Ensure that the socket outlets are located near the equipment and are easily accessible since the
plug on the power supply cord is used as the main disconnect device.
•
The rack, when configured with the units, must meet the safety requirements of UL 60950-1
and IEC 60950-1.
