Rack system safety precautions
The following safety requirements must be considered when the enclosure is mounted in a rack:
•
The rack construction must support the total weight of the installed enclosures. The design should incorporate stabilizing features to
prevent the rack from tipping or being pushed over during installation or in normal use.
•
When loading a rack with enclosures, fill the rack from the bottom up; and empty the rack from the top down.
•
Always remove all power supply modules to minimize weight, before loading the enclosure into the rack.
•
Do not try to lift the enclosure by yourself.
CAUTION:
To prevent of the rack falling over, never move more than one enclosure out of the cabinet at any one time.
•
The system must be operated with low-pressure rear exhaust installation. The back pressure that is created by rack doors and
obstacles must not exceed 5 pascals (0.5 mm water gauge).
•
The rack design should take into consideration the maximum operating ambient temperature for the enclosure. The maximum
operating temperature is 35ºC (95ºF) for controllers and 40ºC (104ºF) for expansion enclosures.
•
The rack should have a safe electrical distribution system. It must provide overcurrent protection for the enclosure. Make sure that the
rack is not overloaded by the total number of enclosures that are installed in the rack. Consideration should be given to the electrical
power consumption rating shown on the nameplate.
•
The electrical distribution system must provide a reliable connection for each enclosure in the rack.
•
Each PSU or PCM in each enclosure has a grounding leakage current of 1.0 mA. The design of the electrical distribution system must
take into consideration the total grounding leakage current from all the PSUs/PCMs in all the enclosures. The rack requires labeling
with “High Leakage Current. Grounding connection essential before connecting supply.”
Installation checklist
This section shows how to plan for and successfully install your enclosure system into an industry standard 19-inch rack cabinet.
CAUTION:
Use only the power cables supplied when installing the storage system.
The following table outlines the steps that are required to install the enclosures, and initially configure and provision the storage system:
NOTE:
To ensure successful installation, perform the tasks in the order presented.
