Dell PowerEdge XR8720t Installation and Service Manual
Environmental Requirements for installing XR8000
The proper installation of the XR8000 chassis and associated sleds requires external-level protection of the system and its components from environmental conditions. The XR8000 unit is designed for expanded temperature range and resistance to seismic events. It is important to note that the unit is not a sealed unit.
General guidelines for maintaining the XR8000:
- It is recommended to keep the system from heat sources and obstructions blocking the airflow.
- It is recommended not to allow spillage of liquid into the system and not to operate when the system is wet.
- If there are any openings in the system, it is recommended not to insert any objects into those points.
- It is highly advised not to tamper with or modify PSUs as it could potentially damage the systems.
- DC power cables should be built according to the cabling instructions her: Cabling-instructions-for--48-to--60-DC-power-supply (dell.com)
Site Planning Recommendation:
- The site should have proper cooling facilities to take care of the operating temperature range of the server.
- The rack or cabinet where the server is going to be installed should have adequate space for cable routing.
- The Rack or cabinet should have enough strength to hold the weight of the server.
- For Conductive dust, the air must be free of conductive dust, zinc whiskers, or other conductive particles. This protects the system from any contamination. This can be accomplished by sufficient air filtration at the ingress to the cabinet.
- For corrosive dust, the air must be free from any corrosive dust and the Residual dust present in the air must have a deliquescent point less than 60% relative humidity.
- The system is best found to operate at -5C to 55C and for some conditions from -20C to 65C. The cabinet could maintain this optimum operating range.
- For protection of the system from humidity it is expected to have an environment with a humidity percent range of 8% RH with -12°C minimum dew point to 80% RH with 21°C (69.8°F) maximum dew point.
- For seismic zones, the XR8000 and XR8720t/XR8620t/XR8610t sleds are rated to support seismic conditions per the NEBS GR-63 spec. Dell standard rails for the system are also rated for the seismic conditions. Note this assumes the rack that the unit is installed in is rated for seismic conditions. It also assumes that the cabinet and other components in the cabinet are rated for seismic conditions.
