Verify that all empty module slots and power supply bays have blanks installed properly. The blanks optimize
the air flow through the chassis and contain EMI.
Blank faceplates and cover panels serve three important functions— They prevent exposure to hazardous voltages and currents inside the chassis; they contain EMI that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system until all cards, face plates, front covers, and rear covers are in place.
