Redundant Power
When two AC power supplies are used, each power supply should be
connected to a separate input circuit. Similarly, when two DC power supplies
are used, each power supply should be connected to separate breakers. This
allows you to remove power from one power supply and replace the inactive
supply while the 3930 is operating.
Dressing the Power Cord
The power cord will be dressed to the right, across the front of the power
supply. It is not appropriate to dress the power cord to the left, across the front
of the 3930 chassis.
This section includes separate instructions for installing DC and AC power
supply modules. Use the instructions that match the type of power supply
being used in your installation.
AC Power Supplies
One or two power supply modules can be installed. If only one module is being
installed, it can be installed in either power supply slot (PSA or PSB).
However, the remaining slot must be covered with a filler plate. The filler plate
is necessary for safety and ensures proper airflow within the chassis. By
default, the chassis has the filler plate installed over PSB on the right.
The AC power supplies use a standard power cord. However, plug
configurations vary around the world. You will need to order a cord with a plug
that matches the local requirements for the installation site.
WARNING:
As per GR-1089 Section 4.12 an external Surge Protective Device
(SPD) is required at the AC input of the 3930.
WARNING:
All AC power cords must meet the requirements of the local and national
electric codes prior to installation.
WARNING:
The AC socket outlet shall be installed near the equipment and
shall be easily accessible.
