   A company is installing a PowerScale rack in a raised-floor data center. The floor tiles are rated to support 500 kg each, and the fully loaded rack weighs 450 kg. The installation team is concerned about the rack's stability and the floor's load-bearing capacity. What should they do to ensure a safe installation?

   • APlace the rack directly on the floor tiles without any additional support, since the rack weighs less than the tile rating.
   • BRemove the side panels of the rack to reduce its weight before installation.
   • CInstall the rack on a wooden pallet to distribute the weight evenly across the floor.
   • DVerify the floor tiles can support the rack's weight and use a floor-mounting kit or spreader plate to distribute the load.

   A data center is installing a PowerScale rack in a room with limited floor space. The rack must be placed against a wall, but the rear of the rack requires 80 cm of clearance for airflow and cable access. The room has only 60 cm of clearance behind the rack. What is the best course of action?

   • AMove the rack away from the wall to provide the required 80 cm of rear clearance, even if it reduces floor space elsewhere.
   • BReduce the number of nodes in the rack to lower the cooling requirement and allow less rear clearance.
   • CPlace the rack against the wall and use a different cable routing method, such as overhead cable trays.
   • DInstall the rack with the front facing the wall and the rear facing the room, providing rear clearance.
