v When powered by multiple AC sources, disconnect all supply power for complete isolation.
v
In order to comply with applicable safety, emission, and thermal requirements, carry out the following
precautions:
– Do not remove any covers
– Populate all rear bays with plug-in modules
v The power connection should always be disconnected prior to insertion or removal of a power supply
unit (PSU) from the enclosure.
v Do not attempt to disassemble the rear sub-chassis from the enclosure.
v Provide a suitable power source with electrical overload protection to meet the requirements laid down
in the technical specification.
CAUTION:
Operating temperatures inside the enclosure drawers can reach up to 60°C. Take care when opening
drawers and removing drive carriers.
v
If any component of the product fails, consult your storage vendor.
v Do not remove Cooling Modules, PSUs or I/O Modules unless you have a replacement model of the
correct type ready for insertion.
v For use in North America, each branch circuit must be rated for 20A.
v This equipment is suitable for connection to an IT power system (Norway).
CAUTION:
Double pole/neutral fusing in PSUs.
Important: The optional RJ45 socket on the I/O module is for Ethernet connection only. Do not
connect it to a telecommunications network.
CAUTION: Due to product acoustics, it is recommended that users wear ear protection for any
prolonged exposure.
CAUTION: To prevent overturning, drawer interlocks stop users from opening both drawers at the
same time. Do not attempt to force open a drawer when the other drawer is already open.
Rack system precautions
The enclosure must be mounted in a rack. Consider the following safety requirements when mounting
the enclosure:
v The rack construction must be capable of supporting the total weight of the installed enclosure(s) and
the design should incorporate stabilizing features suitable to prevent the rack tipping or being pushed
over during installation or in normal use.
v When loading a rack with enclosures, fill from the bottom up; empty from the top down.
v To avoid danger of the rack toppling over, do not slide more than one enclosure out of the rack at a
time.
v The system must be operated with low pressure rear exhaust installation. The back pressure created by
rack doors and obstacles is not to exceed 5 Pascals (0.5mm water gauge).
v The rack design should take into consideration a maximum operating ambient temperature of 35°C.
v 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 total number of units installed in the rack. When
addressing these concerns, consider the electrical power consumption rating shown on the nameplate.
v
The electrical distribution system must provide a reliable ground for each unit in the rack.
v The design of the electrical distribution system must take into consideration the total ground leakage
current from all the PSUs in all the units. The rack might require labeling with “HIGH LEAKAGE
CURRENT. Ground connection essential before connecting supply.”
