1.System needs a fourth PCM for cooling purposes.
2.System needs an eighth PCM for cooling purposes.
Failed power supplies must be replaced as soon as practical. Otherwise, the
Enterprise system will lose its redundancy and result in an outage at the next
PCM failure.
6.4.2 Cooling Requirements
Note – In the Enterprise system, all boards must be adjacent to a PCM. The fans in the PCM cool the boards. The minimum configuration is one PCM for every two adjacent boards.
The power supplies incorporate redundant bulk fan power so that the fans continue to operate in a failed power supply with the redundant fan power from the peripheral power supply.
