4.13 Air/Ventilation Management
Free rack space in the DCR racks must be blocked with blanking panels. Blocking the open space helps
optimize system cooling performance by minimizing short cycling of conditioned air.
Heat loads should be balanced as well as possible among the cabinets. This can be done by distributing
equipment evenly among the cabinets to avoid excessive heat concentration. Refer to Table 3.2 on
page 14 for details.
4.13.1 Ventilation Requirements
• The maximum room temperature for a SmartRow DCR is 85°F (29°C).
• The air-supply inlet temperature to the room should match the output capacity of the
emergency fans.
• If the room is sealed, the air inlet opening size from the building should be 1.5 ft
2
(0.14 m
2
) per
rack.
• If the ceiling space is not open to the rest of the building, a damper or grille of 1.5 ft2 (0.14 m2)
per rack will be required.
4.13.2 Emergency-fan Notes
The emergency-fan assembly for each rack will move nominally 1160 cfm (548 l/s) of air and are powered
from the Control Panel and Fire Suppression System through a factory-installed L5-20 receptacle on top
of the Top Plenum-PDX/PCW.
If the SmartRow DCR is installed in a dedicated room and airflow inlet and outlet openings to the room are
not provided, the emergency fans will remove cabinet heat for only a short time.
4.14 Cable Management
The SmartRow DCR includes factory-suppled cable-management accessories throughout the system,
taking advantage of industry best practices. Follow these cable-management guidelines to help ensure
optimal performance of your system.
4.14.1 Prepare for Cable Management
1. On Top Plenum(s)-Rack, remove the access panel from the front and rear of the plenum and
locate the two rectangular cutouts on each side, shown in Figure 4.30 on the facing page.
