Frame tie-down
The purpose of this installation instruction is to install a frame tie down kit that will
provide frame ruggedizing and the floor tie down hardware for securing an IBM
frame to a concrete floor beneath a 9" to 13" or 12" to 22" raised floor. This kit is
designed to help secure the frame and its contents from damage when exposed to
vibrations and shocks such as those in a seismic event.
Frame tie-down for the z10 BC is a system of adjustable turnbuckles intended to
fasten each corner of the server frames to eyebolts installed in the concrete floor
beneath your computer room raised floor. This appendix describes the installation of
the eyebolts.
You are responsible for obtaining the services of a qualified consultant or structural
engineer to determine what must be done at your particular location to install
four
eyebolts per frame
capable of withstanding a pull force of 975.2 kg (2150 lbs)
each
.
Depending on the amount of space between your raised floor panels and the
concrete floor beneath it, you will need to order either Feature Code 7991, for
raised floors that are 9 to 13 inches above the concrete, or Feature Code 7990, for
floors that are 12 to 22 inches above the subfloor.
Installing the eyebolts
You are responsible for obtaining and installing the eyebolts that will anchor the
frames of your z10 BC server. Following are the specifications for the eyebolts:
v
12.7 mm (0.5 in) diameter, 13 threads per inch (length to be determined by the
qualified contractor who will perform the eyebolt installation)
v
Inside diameter of the eye not smaller than 30 mm (1 3/16 in)
v
Installed so that the center of the eye is not less than 25.4 mm (1 in) nor more
than 63.5 mm (2.5 in) from the surface of the concrete floor.
v
Able to withstand a pull force of 975.2 kg (2150 lbs)
