3 INTRODUCTION
The Vertiv™ SmartRow™ DCX is part of the SmartRow™ platform from Vertiv. The system includes integrated cooling and
power systems. Assembly is a matter of connecting the expansion channels and cabinets, then making electrical and piping
connections.
The basic configuration of the Vertiv SmartRow DCX is a dual-expansion-channel, closed-loop system that provides a room-
neutral solution.
The Vertiv SmartRow DCX must be installed in an indoor, climate-controlled environment. The unit will not protect
electronic equipment if it is installed in an environment subject to extreme temperatures or humidity.
This manual is to be used in conjunction with existing Vertiv product manuals for each component and with site-specific
documentation and drawings. User and installation manuals ship with the equipment and are also available at
www.vertiv.com.
The Vertiv SmartRow DCX is a flexible system that allows customization of rack, power and cooling systems within the
limits of the component parts.
3.1 Operational Overview
The Vertiv SmartRow DCX is an enclosed system to house and cool electronic equipment. The Vertiv SmartRow DCX racks
may house critical IT equipment, optional rack power distribution units and optional, rack-mounted UPS units.
Cooling air is supplied in the row by Liebert® CRV thermal-management units and conveyed to the racks via front
expansion channels. Heated exhaust air from the racks returns to the Liebert CRV through rear expansion channels. An
automatic, emergency ventilation fan system is included to exhaust air in the event of a loss of primary mechanical cooling.
UPS-protected conditioned power is provided to each equipment rack using the Vertiv™ Liebert® MBX mounted overhead
and by rack PDUs mounted inside each rack.
3.2 Vertiv™ SmartRow™ DCX Components
Required components differ based on whether the Vertiv SmartRow DCX includes power and/or redundancy options.
•Vertiv SmartRow DCX Expansion Channels—for each Vertiv™ DCX rack, Liebert® CRV and UPS.
•Liebert® MBX—power-distribution system.
•Liebert® EXM UPS—modular, scalable, with wrap-around BDC and internal or external batteries.
•Liebert® CRV—in-row cooling unit specially configured for use in the Vertiv SmartRow DCX.
•Vertiv™ DCE Rack—network (800mm wide) and server (600mm wide) rack configurations.

4 APPLICATION GUIDELINES
The pre-engineered Vertiv™ SmartRow™ DCX micro-data center delivers highly predictable, repeatable performance in a
variety of applications. This platform maximizes the flexibility in equipment configuration to meet the requirements of a
given application without complicating the overall selection, design or deployment process.
The Vertiv SmartRow DCX system architecture eases the dependence on the site, allowing it to be deployed on raised and
non-raised floors within traditional data centers and in non-traditional IT spaces. When tailoring and deploying a Vertiv
SmartRow DCX for a given application, be sure to follow all of the following guidelines.
When selecting a Vertiv SmartRow DCX system, be sure to exceed the minimum heat-load requirements for the row, do not
exceed the maximum UPS and cooling capacities and select a UPS and busway that offer capacity expansion that is
sufficient to support future growth, if desired. Also, be sure that the initial placement of the cooling units within the row
allows for additional racks and cooling units to be added without having to relocate the existing equipment.
4.1 Environmental Conditions
The Vertiv SmartRow DCX must be deployed in an indoor environment that is maintained year round between 50°F and
85°F (10°C and 30°C) dry bulb and less than 60°F dew point (16°C). It is not suitable for installation outdoors or in
unconditioned spaces (loading docks, unconditioned warehouses, garages, etc). A properly conditioned environment avoids
undesirable condensate formation and ensures that there is air available at suitable conditions for ventilating the SmartRow
system if the Automatic Emergency Ventilation Fans activate.
4.2 Cooling System Design
Adhere to the following guidelines when tailoring a Vertiv™ SmartRow™ DCX cooling system for a particular application.
The automatic, emergency backup ventilation fans are nominally rated for 1,000 cfm. They are designed to provide time to
perform an orderly shutdown of the protected system. Duration of this time is dependent on the size and environmental
conditions of the room external to the Vertiv SmartRow DCX.
NOTICE: If the Vertiv SmartRow DCX is installed in a dedicated room and the airflow inlet and outlet openings are not
provided, the effectiveness of the ventilation system will degrade as the room warms. Providing fresh air relief to the room
and ducting the fan exhaust out of the space will extend run time. Large rooms may be able to run for the full duration of the
UPS battery run time before elevating the room temperature, not requiring the heat to be ducted out.
The Liebert® CRV 600 Series row-based cooling units are 600mm wide and includes 20kW, CRV 35-kW and 40-kW
models.

4.3 Heat Load Calculation
When determining the number of cooling units required to support the SmartRow, make sure to include the total IT
equipment and UPS heat dissipation, along with parasitic room losses. The amount of heat that an IT device rejects may be
very different than the power it consumes. This is common with PoE (Power over Ethernet) switches. Always reference the
heat-dissipation value, not power consumed, on the IT device's specification sheet.
When a UPS system is located within the Vertiv SmartRow DCX and conditioned by the row-based air conditioners, all of
the power leaving the UPS should be fed to the rack-mounted IT equipment. Consult the factory before using the integral
UPS system to power equipment outside of the row.

4.4 Vertiv™ SmartRow™ DCX Equipment Placement within the Row
4.4.1 Cooling Unit and Rack Placement
•Server (600mm wide) and Networking (800mm wide) racks are treated equally and generically referred to as
“racks.”
•When determining the location for Liebert® CRVs within the row, they should be evenly spaced within the rack
lineup to maintain uniform airflow distribution, assuming that the heat-load density is fairly uniform across all of
the racks. If there are a couple of racks within the row with a higher concentration of heat, Liebert® CRVs may
be placed closer to that equipment.
•Do not place two Liebert CRV cooling units next to each other.
•UPS placement does not influence the placement of the cooling units due to the relatively low heat and air-flow
demands of the UPS system.
•If the cooling system is designed for N+1 redundancy, be sure that each rack is within the region of influence of
2 or more Liebert CRVs with sufficient capacity. This will ensure that if any cooling unit fails, another unit will be
able to condition the IT equipment.
•Do not place a Liebert CRV at the end of a row next to a UPS because this would put the Liebert CRV too far
from the rack-mounted IT equipment (see Do not locate Liebert CRV at end of row next to UPS system below).
Figure 4.2 Do not locate Liebert CRV at end of row next to UPS system
4.4.2 UPS System
•Two UPS systems can be located next to each other.
•Three-phase, row-based UPS systems must be placed at the left end of the row (when viewed from the front,
cold side) to ease addition of battery cabinets to the UPS system in the future.
•Battery cabinets can be remotely located, but they will not be conditioned by the row-based cooling system.

4.5 IT Equipment Deployment and Wiring
•Follow industry best practices when deploying IT equipment within the Vertiv™ SmartRow™ DCX.
•To maintain good cold-hot air separation, use blanking panels in all unoccupied RU space.
•Neatly manage all fiber and Ethernet cabling to avoid air-flow restrictions.
•Never route any type of cable within or through the front or rear expansion channels (ECs). Doing so will restrict
air flow and prevent the ECs from being removed from the row equipment.
•When loading IT equipment in the racks, try to distribute the load evenly throughout the row. If there is a higher
density rack, that rack should be closest to a Liebert® CRV.
Vertiv | SmartRow™ DCX Installation Manual | 15

4.6 Settings for the Vertiv™ Liebert® iCOM™ on the Liebert® CRV Cooling Unit
•All of the Liebert CRV cooling units are to be configured in Teamwork Mode 3 with the controlling sensors set
to use the 2T rack-inlet temperature readings.
•The low end of the Liebert CRV fan-speed modulation range is raised at the factory. Do not field-adjust.
•Do not run the Liebert CRV in a staged (staggered) or stand-by configuration. All Liebert CRVs must be
operational at the same time. Ensure your IT equipment dissipates the minimum heat load required by the
entire cooling system on day one.
•For questions on navigating the Liebert iCOM control system call 800-543-2778 for Liebert® Environmental
Technical Support.
