Required Set-Up Tools And Equipment; Heat Load Guidelines - Vertiv SmartRow DCR Installer/User Manual

Read these manuals thoroughly. They include handling instructions and safety notices that must be
followed when unpacking, installing, operating and maintaining the SmartRow DCR.
Adhere to all warnings, cautions and installation, operating and safety instructions on the units and in
their manuals. Only properly trained and qualified personnel should move, install, operate or service this
equipment.

3.4 Required Set-up Tools and Equipment

The following tools are needed to set up a SmartRow DCR:
• 3/4-in. (19-mm) open end wrench or socket
• Ratchet to fit sockets
• Phillips-head screwdriver
• Flat-blade screwdriver
• Forklift or pallet jacks
• Scissors or knife
• Carpenter's level, 3-ft long or longer

3.5 Heat Load Guidelines

Notice
Risk of exceeding cooling capability. Can cause equipment damage.
A SmartRow DCR 20-kW (N) configuration (one PDX/PCW cooling unit) or 20-kW (N + 1)
configuration (two PDX/PCW cooling units) is capable of removing 20 kW of heat. A SmartRow
DCR 36-kW (N) configuration (two PDX/PCW cooling units) can remove 36 kW of heat.
Exceeding that heat load limit, such as by overloading the DCR racks, can cause equipment in
the cabinets to overheat, resulting in equipment damage and voiding warranties.
Refer to the values in Table 3.2 below. The total system capacity and heat loads per cabinet must fall
withing these ranges. We recommend that higher-density loads be located in the center of the SmartRow
configuration. This avoids the need to manually adjust the air dampers when thermal-management units
switch in 2-unit configurations.
