4 Introduction
Active Archive Appliance (A3) v6.5 PowerFile Confidential Racking and Installation Guide
Electrical Distribution System Precautions
• The rack should have a safe electrical distribution system. It must provide overcurrent
protection for the unit and must not be overloaded by the total number of units installed in
the rack. Consideration of the electrical power consumption rating shown on the nameplate
should be used when addressing these concerns.
•
The electrical distribution system must provide reliable grounding for each unit in the rack.
• Each power supply in each unit has an earth leakage current of 1.8mA. The design of the
electrical distribution system must take into consideration the total earth leakage current
from all the power supplies in all the units.
•
For full compliance, the rack should be labeled “HIGH LEAKAGE CURRENT. Earth
connection essential before connecting supply”.
• The fully loaded and configured rack must meet the UL 60950-1 and IEC 60950-1 safety
requirements.
• This equipment is intended to operate with two working PSUs installed in the Power Supply
Module. Before removal/replacement disconnect all supply for complete isolation.
• A faulty Power Supply unit must be replaced with a fully operational unit within 24 hours.
• There are two power supplies in the Archive Engine. It is important to connect both power
supplies. It is recommended that each of the power supplies be attached to a separate UPS
with built in surge protection and line conditioning.
WARNING: DO NOT use a UPS (Universal Power Supply) with automatic shutdown or so called smart
features. The PowerFile system does not support these features. Use a simple UPS to protect your system
from power blackouts and “brownouts.”
