Preparing for installation
Prepare a rack that meets the rack requirements and plan an installation site that meets the
requirements for space and airflow, temperature, humidity, equipment room height, cleanliness, and
grounding.
Rack requirements
IMPORTANT:
To avoid affecting the server chassis, install power distribution units (PDUs) with the outputs facing
backwards. If you install PDUs with the outputs facing the inside of the server, perform onsite survey
to make sure the cables won't affect the server rear.
The server is 4U high and has a depth of 781 mm (30.75 in). The rack for installing the server must
meet the following requirements:
•
A standard 19-inch rack.
•
A clearance of more than 50 mm (1.97 in) between the rack front posts and the front rack door.
•
A minimum of 1200 mm (47.24 in) in depth as a best practice. For installation limits for different
rack depth, see
Table 2 Installation limits for different rack depths

1000 mm
(39.37 in)
•
The H3C cable management arm (CMA) is not supported.
•
A clearance of 60 mm (2.36 in) is reserved from the server rear to the rear rack
door for cabling.
•
The slide rails and PDUs might hinder each other. Perform onsite survey to
determine the PDU installation location and the proper PDUs. If the PDUs hinder
the installation and movement of the slide rails anyway, use other methods to
support the server, a tray for example.
1100 mm
(43.31 in)
Make sure the CMA does not hinder PDU installation at the server rear before
installing the CMA. If the CMA hinders PDU installation, use a deeper rack or change
the installation locations of PDUs.
1200 mm
(47.24 in)
Make sure the CMA does not hinder PDU installation or cabling. If the CMA hinders
PDU installation or cabling, change the installation locations of PDUs.
