10 Sun Server X4-2 Installation Guide • February 2014
Note – Circuit breakers are supplied by the customer. One circuit breaker is required
for each server power cord.
In addition to circuit breakers, provide a stable power source, such as an
uninterruptable power supply (UPS) to reduce the possibility of component failures.
If computer equipment is subjected to repeated power interruptions and fluctuations,
then it is susceptible to a higher rate of component failure.
Grounding Guidelines
The rack must use grounding-type power cords. For example, Oracle’s Sun Rack II
has three-wire, grounding-type power cords. Always connect the cords to grounded
power outlets. Because different grounding methods are used, depending on
location, check the grounding type, and refer to documentation, such as IEC
documents, for the correct grounding method. Ensure that the facility administrator
or qualified electrical engineer who verifies the grounding method for the building
and performs the grounding work.
Environmental Requirements
The following table lists the temperature, humidity, and altitude specifications, as
well as acoustic noise, vibration, and shock specifications.
