2. Unpacking and Installing the Rack Frame
NOTE : When installing the rails in the rack frame that has already been in use, perform the
installation works in “3. Installing Rails”and the following steps.
NOTE : If you use rack frames other than Hitachi racks, note the following:
• Replace the values of the depth and width described in “2.1 Unpacking the RKU
Rack Frame”with those of your rack frames.
• If the total weight of the storage system is less than 830 kg, follow the procedure
described in “2.1 Unpacking the RKU Rack Frame”. If the total weight of the
storage system is 830 kg or more, calculate the sum of the storage system weight
and the rack weight, and then consult with the person in charge of the building to
which the storage system is carried about the procedure.
2.1 Unpacking the RKU Rack Frame
Figure 2-1 shows the packed status of the RKU Rack Frame.
1. Unpacking
NOTE : • Unpack it indoors.
Especially, do not unpack it in such places with the outdoor dust, the direct sunlight,
and the inltration of rainwater.
• Work on the unpacking in the place where a rapid difference of temperature does
not occur.
It may have dew condensation when it is unpacked in the place where a difference
of temperature is extreme.
• Do not push the side of the RKU rack frame.
For moving the RKU rack frame, push it from the front.
(1) Remove a wooden cap and polyethylene bag from the RKU Rack Frame.
(2) Remove two cotton tapes which fasten the rear door.
(3) Remove four crepe tapes  which x the leveling bolt.

2. Checking external appearance of the Storage System
Check the external appearance of the rack frame for distortion or damage owing to the transport.
Figure 2-2 External Appearance of Rack Frame
3. Checking the Storage System conguration and supplements
Check if the components of the Storage System (their model names, product serial numbers and
quantities) agree with those in the packing list shipped.

4. Installation Area/Maintenance Area and Earthquake-resistant Plan
(1) Installation area (for one rack) and maintenance area
Figure 2-3 shows installation and maintenance areas for the A-6516-RKU3 rack frame and a cut-
out gure using a free access floor.
NOTE : Since installation areas vary depending on the size of systems, layout, and conditions
of buildings, it is required to contact a construction professional of carry-in buildings.
Figure 2-3 Installation and Maintenance Areas of Rack Frame
When the RKU racks are installed, the right and left side clearance (a) and the front and rear side
clearance (b) must be secured. The clearance (a) and the clearance (b) are calculated from the total
weight of the storage system and the floor load capacity.
When installing one RKU rack, calculate the total weight of the storage system according to “(2)
Calculation of total weight of storage system”, and then see one of the tables by floor load capacity
in “(3) Reference matrix of clearances between racks” to nd the values of (a) and (b).

When installing two or more RKU racks with them connected, calculate the total weight of the
storage system according to “(2) Calculation of total weight of storage system”, and then calculate
(a) and (b) by using the calculation formula shown in “(4) Installation area when installing
multiple RKU racks with them connected”. For (a), allow at least 200 mm clearance to secure the
maintenance area.
(2) Calculation of total weight of storage system
The total weight of the storage system is calculated by summing up the weight of each component.
The weight of each component is shown below.
Component Weight (kg) Remarks
RKU rack
(with side covers)
213 Weight of 43U rack with side covers
RKU rack
(without side covers)
173 Weight of 43U rack without side covers
Side covers 40 Weight of only side covers for 43U rack
CBX (VSP 5500/5500H) 75 Two CBXs are required per CBX pair.
Two Controller Boards are installed per CBX.
CBX (VSP 5100/5100H) 60 Two CBXs are required per CBX pair.
One Controller Board is installed per CBX.
HSNBX 15 Two HSNBXs are required for the rst CBX pair only. No
HSNBX is required for the second or third CBX pair.
SBX 96 SBX composed of four Drive Boxes (24 kg per Drive Box)
UBX 216 UBX composed of eight Drive Boxes (27 kg per Drive Box)
FBX 152 FBX composed of four Drive Boxes (38 kg per Drive Box)
NBX 84 NBX composed of four Drive Boxes (21 kg per Drive Box)
Maintenance
equipment
75 A weight of a lifter is also added to calculate the total weight.
Cables (just for your
information)
10 kg/m2Not required for calculation of the total weight. (Considered
for the tables in (3) and the calculation formula in (4).)
The weight of each component is the weight when the component contains the maximum number
of parts.

For example, the total weight of the storage system when two SBXs and one UBX are installed in
the single CBX pair conguration is calculated as follows:
RKU rack (213 kg) + DKC (75 kg 2) + HSNBX (15 kg 2) + SBX (96 kg 2) + UBX (216 kg)
+ maintenance equipment (75 kg) = 876 kg

(4) Installation area when installing multiple RKU racks with them connected
When connecting multiple racks, calculate the right and left side clearance (a) according to the
formula shown below. Note that the minimum clearance of 200 mm must be secured to perform
maintenance work even though the calculated value is smaller than 200 mm.
[(a):Right and left side clearance (mm)] = (Total weight of storage system (kg)) (1.15 + [(b):Front
and rear side clearance (mm)] 1000) ([Floor load capacity (kgf/m2)] - 10) 1000 - 600 
[Number of connected racks]
Example where the total weight of the storage system is 1,000 kg (including maintenance
equipment), the front and rear side clearance is 1,600 mm, the floor load capacity is 300 kgf/m2,
and the number of connected racks is two:
1000 (1.15 + 1600 1000) (300 - 10) 1000 - 600 2
= 53.918...
≒54
∴(a) ≥54 mm
The calculation of the above example shows that a 54 mm or larger clearance must be secured on
each of the right and left sides of the racks.
However, allow at least 200 mm right and left side clearance (a) to secure the maintenance area.

2.3 Installation of RKU Rack and Side Cover
• Make sure that the equipment is moved by two or more persons.
• Be sure to move the equipment by pushing it from the front face in the direction of movement.
It is acceptable for two persons to move the equipment carefully from the front face and rear
face only when installing it. Do not push the equipment from the side face in principle.
• The front caster of the rack frame is not a rotary type but a xed type not to incline the
equipment at over the tipping angle. Therefore, the equipment should not be rotated quickly.
Moving the equipment normally
Move the rack frame only from the front face in principle.
Push the rack frame slowly with thumbs and the bases of them on both ends of the front face.
When changing moving direction, do so little by little in cooperation with an assistant instead of changing
moving direction quickly.
An assistant should not pull only the rear door strongly because doing so may cause the deformation of
the rear door.

Moving the equipment forward with limited space
When moving the equipment in the direction of the front of the rack frame, two persons must cooperate.
One pulls the front face of the rack frame in the direction of the installation location and the other pushes
the rear face of the rack frame with hands on the both ends of the rear door at the position that is more
than 50mm far from the door lock holding side covers. Do not push the door lock directly.

Moving the equipment in a lateral direction
When locating the equipment next to the equipment that was already installed, two persons must
cooperate. One pulls the front face of the rack frame and the other holds the side face of the rack frame to
move it.
Push the side face of the rack frame slowly with thumbs and bases of them on both edges of the side
cover of the middle rack. Do not push the side face when the equipment is in a sloping place. Some of the
equipment that has an upper center of gravity may fall down. Pushing the central part of the side cover
excluding the part within 40mm from the edge, or boundary part of the side cover strongly may make the
side cover caved in.
