Safety Guidelines
The RJ45 sockets on the motherboard/PCI cards are for Ethernet
connection only and must not be connected to a telecommunica-
tions network.
Drives are fragile and must be handled with care during removal/
replacement.
1.3. Rack System Safety Precautions
The rack construction must be capable of supporting the total weight
of the installed enclosure(s) and the design should incorporate sta-
bilizing features suitable to prevent the rack from tipping or being
pushed over during installation or in normal use.
When loading a rack with the units, fill the rack from the bottom up
and empty the rack from the top down.
Before loading the chassis into a rack, remove all PSU modules and
drives to minimize weight.
CAUTION: To avoid danger of the rack toppling over, under no
circumstances should more than one enclosure be drawn out of the
cabinet at any one time.
The back pressure created by rack doors and obstacles must not
exceed 5 pascals (0.5mm water gauge).
The rack design should take into consideration the maximum oper-
ating ambient temperature for the unit, which is 35°C.
The rack should have a safe electrical distribution system. It must
provide overcurrent protection for the unit and must not be over-
loaded by the total number of units installed in the rack. When ad-
dressing these concerns, consider the electrical power consumption
rating shown on the product.
The electrical distribution system must provide a reliable earth for
each unit and for the rack.
Each Power Supply Unit has an earth leakage current of 1.4mA. The
design of the electrical distribution system must take into consider-
ation the total earth leakage current from all the power supplies in
all the units. The rack requires labelling with the following: “HIGH
LEAKAGE CURRENT. Earth connection essential before connecting
supply”.
When configured, the rack must meet the safety requirements of UL
60950-1:2005 (2nd edition) and IEC 60950-1 2nd edition.
