Preparing the Electrical Circuits

In planning where to place your equipment, remember that each of the following
items requires access (by way of a separate power cord) to a power outlet:
Sun Enterprise 6500/5500/4500 system
External peripherals
Monitor used for diagnostics

Enterprise 6500/5500 Cabinet Systems

The 16-slot and 8-slot system cabinets require a 30A circuit and a detachable cable.
The equipment relies on the protective device in the building installation, thus it
requires a 30A circuit breaker.
Caution – Do not attach other electrical equipment to the server AC circuit; server
reliability may be affected.
Note – If the appropriate electrical receptacle is not available in your country, the
connect may be removed from the cord. The cord can then be permanently
connected to a dedicated branch circuit by a qualified electrician. Check local
electrical codes for proper installation requirements.
Caution – The system cabinet has a high leakage current to ground. Strictly observe
the following instructions to reduce the risk of electric shock.
The system requires an electrical circuit that is grounded to earth. The UL1950,
CSA950, and EN60950 specify:
An insulated earthing conductor that is identical in size, insulation
material, and thickness to the earthed and unearthed branch-circuit
supply conductors, except that it is green with or without one or more
yellow stripes, is to be installed as part of the branch circuit that supplies
the unit or system. The earthing conductor described is to be connected
to earth at the service equipment or, if supplied by a separately derived
system, at the supply transformer or motor-generator set.
