1.3 Airflow requirements
Ensure that both the front and rear of the ActiveScale X100 stay clear of any materials that may block or
disrupt the airflow in any way. Disrupting the airflow can cause the system to overheat, which may affect
performance or cause damage to the system.
The following rack airflow principles should be considered for best results:
• Controlled air conditioners that are functional and can sufficiently maintain specified system
operating temperatures should be located in the facility where the system will be installed.
• The airflow in and out of the equipment must not be restricted.
1.4 Servicing space requirements
Space at the front and the rear of the system is required to service system components. The front space
requirement is based on the length of the longest system component, plus the space necessary to fit a

1.5 Available kits and upgrades
This section describes the upgrades and supplemental kits that are available for the ActiveScale X100.
1.5.1 Scale up kits
Each scale up kit contains additional sleds that increases data storage capacity by either:
• 0.84 PB using 10 TB HDDs.
• 1 PB using 12 TB HDDs.
• 1.18 PB using 14 TB HDD’s.
For more information, refer to Installing scale up kits on page 139.
1.5.2 Scale out kits
Storage capacity can be even further increased by connecting a new ActiveScale X100 to an existing
system.
For more information, refer to Installing scale out kits on page 152.
1.5.3 Rack seal kits
You can use the rack seal kit to seal racks with third-party, liquid-cooled doors.

2.1 Required equipment for installation
Before you begin the installation, ensure that you have the following items:
• Socket set or socket conversion for a powered drill
• 9/16" socket drive
• Drill
• Adjustable wrench
• Level
• Box cutter
• Tape measure
•Ladder
• Torque wrench
2.2 Servicing space requirements
The ActiveScale X100 requires that enough space be available at the front and the rear of the system to
service system components. The front space requirement is based on the length of the longest system
component, plus the space necessary to fit a person servicing the system. The rear space requirements is
based on space a technician would need to service all of the parts at the rear of the unit.
Figure 2-17. Minimum servicing space required
2.3 Delivery route inspection
During the receiving process, the entire system will need to be moved through the facility until it reaches
the data center or computer room where it will be installed. This section describes the considerations that
the installation team should make before receiving the system and moving it through the facility.
2.3.1 Walking path inspection
Walking paths must be clear of obstructions and wide enough to allow passage of the system to the site
where it will be unpacked. The following is a list of obstructions to consider when conducting a walking
path inspection:

•Cables - consider removing cables, including ramped cable covers, from the walking path before
moving the pallet. Leaving the cables in place creates a safety hazard for the installation team and can
damage the cables.
•Lift locations - there may be locations along the walking path where the system must be lifted in
order to proceed. Make sure that lift equipment is available at this location on the day of the delivery.
•Elevators - ensure that any elevators that will be required to lift the equipment to the data center/
computer room are rated to carry the full load of the system plus passengers.
2.4 Airflow considerations
Ensure that both the front and rear of the ActiveScale X100 stay clear of any materials that may block or
disrupt the airflow in any way. Disrupting the airflow can cause the system to overheat, which may affect
performance or cause damage to the system.
The following rack airflow principles should be considered for best results:
• Controlled air conditioners that are functional and can sufficiently maintain specified system
operating temperatures should be located in the facility where the system will be installed.
• The airflow in and out of the equipment must not be restricted.

2.6 Network requirements
The ActiveScale system provides six 10G Ethernet ports for connecting to a customer's network. However,
the customer must provide six fiber cable drops from the network to the rack. The fiber cable must be LC
to LC multi- mode fiber optic patch cable (LC multi-mode 50/125mm MMF OM3 or OM4 10Gb laser
optimized fiber). These cables must comply with the Ethernet 10GBASE-SR standard. Ensure that you do
not exceed the specified maximum 10GBASE-SR cable length for the cable type chosen. For example, do
not exceed a length of 400 m if you are using 10G OM4 multi-mode cables.

3.1 Packaging inspection
Important: Ensure that all ShockWatch and TiltWatch sensors are checked and
recorded.
As you unpack the system, look for obvious signs of damage. The following scenarios are the most
common ways a package can be damaged:
• Crushed corners caused by dropping the package.
• Split seams caused by excessive shearing force placed on the container.
• Punctures caused by a sharp object striking the packaging.
• Water damage caused by contact with a water source or storage in an overly humid environment.
3.2 Unpacking the ActiveScale X100
The ActiveScale X100 ships on a padded pallet containing mounting hardware and system unloading
ramps.
To unpack the ActiveScale X100:
1. On the cardboard side panels, verify that the ShockWatch and TiltWatch sensors have not been
tripped. If any of the sensors have been tripped, report the damages to Western Digital Corporation
Support.
2. Cut the plastic bands holding the top cap to the cardboard panels.
