Preparing for installation
The server is 2U high. Prepare a standard 19-inch rack to install the server.
Plan an installation site that meets the requirements of space and airflow, temperature, humidity,
equipment room height, cleanliness, and grounding.
Installation site requirements
Space and airflow requirements
For convenient maintenance and heat dissipation, make sure the following requirements are met:
•
A minimum clearance of 635 mm (25 in) is reserved in front of the rack.
•
A minimum clearance of 762 mm (30 in) is reserved behind the rack.
•
A minimum clearance of 1219 mm (47.99 in) is reserved between racks.

Temperature, humidity, and altitude requirements
To ensure correct operation of the server, make sure the room temperature, humidity, and altitude
meet the requirements as described in "
Appendix A Server specifications
."
Cleanliness requirements
Mechanically active substances buildup on the chassis might result in electrostatic adsorption, which
causes poor contact of metal components and contact points. In the worst case, electrostatic
adsorption can cause communication failure.
