System precautions
Ensure that the voltage and frequency of the power outlet that is used matches the
electrical rating labels on the equipment.
Wear antistatic wrist straps when handling any magnetic storage devices, CPU/Memory
boards, or other printed circuit boards.
The computer has three autoranging power supplies that use nominal input voltages
of 100 to 240 V AC at 47 to 63 Hz. Sun products are designed to work with single-phase
power systems with a grounded neutral conductor. To reduce the risk of electric shock, do
not plug Sun products into another type of power source. Contact your facilities manager
or qualified electrician if you are unsure of what type of power is supplied to your building.
Avaya recommends that you use one of the following power schemes:
● Connect the computer using two (2) 2KVA Uninterruptible Power Supplies (UPS) (or
equivalent), each powered by a nonswitched, dedicated, 15-amp circuit. Connect two of
the power supplies to one UPS, and the third power supply to the second UPS. The
monitor and external peripherals can also be connected to the second UPS.
● If not using a UPS, each power supply should be connected to a nonswitched,
dedicated, 15-amp circuit. The monitor and external peripherals should be connected to
a separate circuit.
Each of the following items require a separate power cord:
● Power supplies in the computer (3 power cords)
● External peripherals
● Monitor
