Attention:
v
For reliable operation do not use Ground Fault Circuit Interrupter (GFCI), Earth
Leakage Circuit Breaker (ELCB), or Residual Current Circuit Breaker (RCCB)
type circuit breakers with the storage system. The storage system is certified for
safe operation and compliant with IEC, EN, UL, and CSA 60950-1 standards. If
local electrical practice requires leakage detection circuit breakers, they must be
rated at minimum to 15 mA or larger to reduce the risk of outage due to
spurious actuation.
v Do not exceed the wire rating of the facility and ensure that separate protected
branch circuits are used for each cord in planning for redundancy.
Power consumption and environmental information
When you are planning to meet the power requirements, consider the power
consumption and other environmental points of the storage system.
Note: The power consumption for the operating disk enclosure is typically 275
watts - 300 watts. The power consumption for the operating High Performance
Flash Enclosure Gen2 is 500 watts.

Notes:
1. LWAd is the statistical upper-limit A-weighted sound power level (rounded to the
nearest 0.1 B).
2. LpAm is the mean A-weighted emission sound pressure level that is measured at the
1-meter bystander positions (rounded to the nearest dB).
3.
10 dB (decibel) = 1 B (bel).
4. All measurements made in conformance with ISO 7779 and declared in conformance
with ISO 9296.
Planning for environmental requirements
You must install your storage system in a location that meets the operating
environment requirements for correct maintenance.
