Temperature and humidity
Table 1 on page 4 lists the acceptable temperature and humidity ranges in which
the storage subsystem is designed to operate.
Notes:
1. The non-operating environment must not exceed the operating environment
limits for longer than 60 days.
2. The storage environment must not exceed the operating environment limits for
longer than 1 year.
3. Substantial deviations from the suggested operating range, in either direction, if
sustained for extended periods of time, will expose the unit to greater risk of
failure from external causes.
Electrical requirements
Consider the following information when you prepare the installation site:
v Protective ground: Site wiring must include a protective ground connection to
the ac power source.
Note: Protective ground is also known as safety ground or chassis ground.
v Circuit overloading: Power circuits and associated circuit breakers must provide
sufficient power and overload protection. To prevent possible damage to the unit,
isolate its power source from large switching loads (such as air conditioning
motors, elevator motors, and factory loads).
v Power failures: If a total power failure occurs, the unit automatically performs a
power-on recovery sequence without operator intervention after power is
restored.
Site wiring and power
The storage subsystem uses wide-ranging redundant power supplies that
automatically accommodate voltages to the ac power source. The power supplies
operate within the range of 90 V ac to 264 V ac, at a minimum frequency of 50 Hz
and a maximum frequency of 60 Hz. The power supplies meet standard voltage
requirements for operation both inside the U.S.A. and outside the U.S.A. They use
standard industrial wiring with line-to-neutral or line-to-line power connections.
