   A customer is adding a new PowerScale F600 node to an existing rack. The rack is in a raised-floor data center with a 30 kW per-rack power budget. The new node requires 1.2 kW. The current rack load is 28.5 kW. The customer wants to keep the rack's redundant power feeds balanced. What should you do before scheduling the installation?

   • AVerify the rack's total load after adding the node stays within the 30 kW budget and that both power feeds can handle the new load.
   • BSchedule the installation for a maintenance window when the rack's cooling system can be temporarily disabled to reduce power draw.
   • CAsk the customer to upgrade the rack's power distribution unit to a higher capacity model before installation.
   • DInstall the node and rely on the rack's power monitoring to alert if the load exceeds the budget.
