The Earthquake Kit for the 9176 on a raised floor 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. FC 8014 supplies parts to
cover raised floor heights from 241.3 mm to 1320.8 mm (9.5 in - 52 in).
Measure the height from the concrete floor to the top of the raised floor as indicated in Figure 1.Figure 1. Turnbuckle assembly
Use the raised floor height (specified as 'H') and Table 1 to determine the specific
hardware that you need to select from the Earthquake Kit.

Important: Make a note of the measurement information and hardware
selection, as it will be needed later in the server installation.
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. These
eyebolts should be capable of withstanding the appropriate seismic forces for a frame weighing up to
1308 kg (2885 lbs) with the center of gravity 1270 mm (50 inches) from the bottoms of the frame
casters and at the center of the frame.
