Setting Up Your Server 3-9
Installing the Core Nuts
Install three core nuts on the front of the rack for each of the right and left sides and also two core
nuts on the rear of the rack for each of the right and left sides.
Install three core nuts in 1U (the minimum unit of rack height). Three slots (angle holes) are
opened per 1U of a rack. Install the core nuts at the three slots. (For any NEC rack, round marks
are put in the unit of 1U.) For two core nuts installed on the front of the rack, the upper and lower
nuts are used to fix the front of the rail assembly, and the center is used to support the set screw of
the server. The core nuts installed on the rear of the rack are used to fix the rear of the rail
assemblies.
Hang either clip of a core nut on a square hole on the rack and insert another clip into the hole by
using a tool such as a flat tip screwdriver.
NOTE:
Confirm that all the core nuts are installed at the level.
