Sun Enterprise 6500/5500/4500 Systems Reference Manual

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.

Note -

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