IBM XIV Gen3 Series, Planning Manual

Installation and safety requirements
If the cables are too long, there might not be enough room inside of the rack to
handle the extra length and the extra cable might interfere with the servicing tasks,
preventing concurrent repair.
IBM Corporate Safety restricts the servicing of your overhead equipment to a
maximum of 10 feet from the floor. Therefore, your power source must not exceed
10 feet from the floor and must be within 5 feet of the top of the rack. Servicing
any overhead equipment higher than 10 feet requires a special bid contract.
Contact your IBM Representative for more information about special bids.
Preparing for the ruggedized rack
If the optional ruggedized rack (feature code 0080) was ordered, the customer must
purchase fastening hardware and prepare the location where the kit is to be
installed before an IBM service representative can install the ruggedized rack on
any of your XIV systems.
Procedure
The customer must perform one of the following procedures before the ruggedized
rack installation, depending upon whether the XIV system sets on a raised or a
non-raised floor. For either type of installation, work with a consultant or
structural engineer to ensure that the site preparations meet the requirements.
v Raised floor with a depth of 228.6 - 558.8 mm (9 - 22 in.)
1. Consult the manufacturer of the floor panels that are used at the installation
site to ensure that the floor panels can sustain a concentration load of 454 kg
(1000 lb) per rack. More panel supports (pedestals) might be required to
restore structural integrity of the panels. For multiple rack installation, two
casters might induce a concentration load as high as 907 kg (2000 lb) on a
floor panel.
2. Obtain the service of a qualified consultant or structural engineer to
determine the appropriate heavy-duty concrete or slab-floor eyebolts.
Each eyebolt must withstand 2268 kg (5000 lb) pull force per eyebolt.
3. Purchase four 0.5x13-in. heavy-duty concrete or slab eyebolts, with an
internal diameter of 1-3/16 in.
4. Install the eyebolt fasteners 527.8 mm (20.8 in.) side to side and 965 mm (38
in.) front to back.
