2.3 Electrical Safety Precautions
Ensure that the voltage and frequency of the power outlet to be used match the
electrical rating labels on the equipment.
Wear antistatic wrist straps when handling any magnetic storage devices,
system boards, or other printed circuit boards.
Use only properly grounded power outlets as described in the installation guide.
Caution – Do not make mechanical or electrical modifications. Sun Microsystems™
is not responsible for regulatory compliance of modified systems.
Caution –
The chassis AC power cords must remain connected to ensure a proper
ground.
2.4 System Cabinet Safety Precautions
All system cabinets should be anchored to the floor, ceiling, or to adjacent frames,
using the manufacturer’s instructions.
Free-standing cabinets should be supplied with an anti-tilt feature, which must be
extended to a minimum of 10.6 inches (27 cm) from the front edge of the rack, or at
least sufficiently to support the weight of the system when extended on its slides.
This prevents instability during installation or service actions.
Where an anti-tilt feature is not supplied and the system cabinet is not bolted to the
floor, a safety evaluation must be conducted by the installation or service engineer.
The safety evaluation determines the cabinet stability when the system is extended
on its slides, prior to any installation or service activity.
Prior to installing the system cabinet on a raised floor, a safety evaluation must be
conducted by the installation or service engineer. The safety evaluation ensures that
the raised floor has sufficient strength to withstand the forces upon it when the
system is extended on its slides. The normal procedure in this case would be to fix
the system cabinet through the raised floor to the concrete floor below, using a
proprietary rackmounting kit for the purpose.
