CAUTION: The optional RJ45 socket on the I/O module
is for Ethernet connection only and must not be
connected to a telecommunications network.
Before installing the disk shelf, make sure that you have read and understand these power and
electrical safety rules.
•
The enclosure must only be operated from a power supply input voltage range of 100-240
VAC.
•
The rack design should take into consideration the maximum operating ambient temperature
for the unit, which is 40 degrees C.
•
The rack should have a safe electrical distribution system.
It must provide over-current protection for the unit and must not be overloaded by the local
number of units installed in the rack.
When addressing these concerns consideration should be given to the electrical power
consumption rating shown on the name plate.
•
A safe electrical earth connection must be provided to the power supply cords.
•
This equipment is designed for connection to a grounded outlet.
The grounding type plug is an important safety feature.
To avoid the risk of electrical shock or damage to the equipment, do not disable this feature.
•
The electrical distribution system must provide a reliable earth connection for each unit in the
rack.
•
DC-based systems must be installed in a restricted access location and the two input power
terminals for the DC power supply must be connected to separate isolated branch circuits.
•
Provide a suitable power source with electrical overload protection to meet the requirements
laid down in the technical specification.
Before operating, replacing, or removing the disk shelf or disk shelf components, make sure that
you have read and understand these management safety rules.
•
In order to comply with applicable safety, emission, and thermal requirements, no covers
should be removed and all bays must be populated with plug-in modules.
•
Since all plug-in modules and blank plates are part of the fire enclosure, they must only be
removed when a replacement can be immediately added.
The system must not be run without all modules or blanks in place.
•
To reduce the risk of personal injury or equipment damage, allow internal components time to
cool before touching them.
•
When removing a disk shelf from a movable cabinet or a rack, empty from the top down.
•
To avoid danger of the rack toppling over, do not slide more than one enclosure out of the rack
at a time.
•
Permanently unplug the unit before you move it or if you think it has become damaged in any
way.
•
The power connection should always be disconnected prior to removal of a PSU from the
enclosure.
DANGER: Do not remove a faulty PSU unless you have
a replacement PSU of the correct type ready for
insertion. The system must not be run without all units or
module blanks in place.
