Cooling and Power Issues

There should be one power/cooling module (PCM) for every two boards to adhere to cooling and power requirements. The PCMs must be installed adjacent to populated board slots to ensure the fan in the PCM can cool the respective boards.

All empty board slots in Enterprise 4500 or 5500 systems must have a filler panel installed to ensure proper cooling and for EMI protection. All empty slots in Enterprise 6500 systems must have load boards installed.
