1. Access t o t his equ ipment is gr anted only to t rained op erators an d
service personnel who h ave been instructed of a nd f ully u nderstand
the possible hazardous conditions and the consequences of accessing
non-field-serviceable units, e.g., system backplane or power supplies.
2. Unplug the s ystem bef ore you m ove i t or when i t has bec ome
damaged.
RELIABLE EARTHING!
Particular a ttention s hould be g iven to pr epare r eliable earthing with t he
power supply connections other than direct connections to the branch circuit
(e.g., us e of po wer strips). T he A C po wer c ords pr ovide t he m ain ear th
connection. Check proper grounding before powering on the enclosure.
OVERLOADING PROTECTION!
1. The enclosure should be installed according to specifications on a
chassis l abel. P rovide a s uitable po wer s ource w ith electrical o verload
protection.
2. Do not overload the AC supply branch circuit that provides power to the
rack. T he t otal r ack l oad should n ot ex ceed 8 0 percent of t he br anch
circuit rating.
BATTERY USE WARNING!
Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to local ordinance.

THERMAL PRECAUTIONS:
1. If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient.
Appropriate m easures, s uch as increasing a irflow, s hould b e available
to maintain the temperature below 35°C.
2. The openings on the enclosure are for air convection. DO NOT COVER
THE OPENINGS.
3. To comply with safety, emission, and thermal requirements, all module
bays should be populated with plug-in modules. The system should not
be operated with the absence of any covers.
HANDLING PRECAUTIONS:
1. The s ystem c an ei ther be i nstalled i nto a s tandard EIA-310 1 9” r ack
cabinet or placed o n a desktop. Mec hanical loading of t he e nclosure
should be carefully handled to avoid hazardous condition. A drop or fall
could cause injury.
2. Lay this system on a reliable surface with desktop installation. A drop or
fall can cause injury.
3. Mounting this enclosure requires two people.
4. The enc losure c an weigh up t o 37Lbs ( 17kg) without di sk dr ives. With
disk drives loaded, the enclosure can weigh up to 60lb (24kg). A reliable
surface should be available to support this weight.
5. Disk drives should be installed after the enclosure is securely installed.
