Thermal
The chassis is cooled from front to back, as with typical rack systems. There are separate paths for the exhaust, keeping the PSU
exit air isolated from the sled exit air. The sled air flow is controlled by the rear 80mm fans, while the PSU air flow is controlled by the
PSU fans located toward the front of the PSUs.
Ambient Temperature Requirements
In general the EMC PowerEdge MX7000 shall support an ambient operating temperature of 10° C to 35° C Some module
configurations (e.g., compute sleds with special high wattage CPU SKU's) aren't able to support 35° C ambient with full
performance. And there are some modules and features that can't be supported at Fresh Air ranges.
