fix it with a cable clamp, etc. If it is loosened, the connection is damaged, and it causes an
electric shock or fire.
1.
If you newly install the storage system, make sure that all breakers of the PDUs are off.
If you add the Drive Box, go to
because breakers of the PDUs need not to be turned off.
2. Insert the power cable plug completely into the receptacle on the each Power Supply.
3. Fix the power cable holder to the power cables.
4.
In case of SBX/UBX/FBX, correct the twisted power cable and fix it to the rail with omega clips.
5. Insert the power cable plug into the PDU.
NOTE : • Be sure to plug the power cable for the Power Supply 1 in the receptacle of the PDU
-xx0.
Be sure to plug the power cable for the Power Supply 2 in the receptacle of the PDU
-xx1.
If they are plugged in the receptacles of the PDUs on the same side, the function of
the duplicated power supply does not work.
• Do not plug any cable other than the power cable of the mounted Storage System in
the outlet of the PDU.
• Connect DKC-0, DKC-1, HSNBX-0, and HSNBX-1 to the same PDUs (two PDUs
in total on the right and left sides).
Connect DKC-2 and DKC-3 to the same PDUs (two PDUs in total on the right and
left sides).
Connect DKC-4 and DKC-5 to the same PDUs (two PDUs in total on the right and
left sides).
Connect all Drive Boxes (DB-xxx) composing one DKU to the same PDUs (two
PDUs in total on the right and left sides). However, when DKU is UBX, Drive
Boxes can be separately connected to two different PDUs on the right side and to
two different PDUs on the left side (use four receptacles on each PDU).
When DKU is SBX/FBX/NBX, Drive Boxes can be separately connected to two
different PDUs on the right side and to two different PDUs on the left side (use two
receptacles on each PDU).
