Site Preparation - IBM XIV Gen3 Series Planning Manual

For the most reliable operation, do not use Ground Fault Circuit Interrupter
(GFCI), Earth Leakage Circuit Breaker (ELCB), and Residual Current Circuit
Breaker (RCCB) type circuit breakers with XIV systems. The XIV system is certified
for safe operation and is compliant with IEC, EN, UL, CSA 60950-1 standards.
However, if leakage detection circuit breakers are required by local electrical
practice, the breakers must be sized for a leakage-current rating of 300 mA or
greater to reduce the risk of server outage caused by erroneous and spurious
tripping.

Site preparation

The IBM service representative can only minimally reposition the rack at the
installation site, as needed to service the XIV system. The customer is responsible
for using professional movers or riggers in the case of equipment relocation or
disposal.
Attention: Do not tilt the XIV system rack more than 12.5 degrees.
If more clearance is needed for models 281x-114, 281x-214, or 281x-314 racks, the
weight-and-height-reduced shipping (feature code 0200) must be ordered to reduce
the height of the rack. When this option is ordered, data modules 12 - 15 are
shipped separately, and the rack top cover can be removed by the IBM service
representative before the XIV system is moved to its final location by professional
movers.
