Power Supplies and Power Cable
The openGear frame comes standard with one power supply, with a second optional power supply
available for redundancy. For redundancy, and in applications where the equipment is used in a critical
signal path, we recommend that two power supplies be used in the openGear frame. One A/C power
cable has been provided with each power supply ordered.
For further redundancy, each power cord should be connected to a separate power source for protection
against failure of the A/C power circuit. In the event of one power supply failure, the frame load is
seamlessly transferred to the other redundant power supply. Although the power supply is “hot-
swappable” turning the power supply off before inserting or removing it from the frame will increase
the life span of the connectors.
Required Power Supplies
The OG3-FR uses the PS-OG3 power supply.
Power Supply Connectors (PSU1, PSU2)
There are two power supply connectors located on the back of the openGear frame:
• PSU1 — This connector is designated as the AC Connector for the main power supply.
• PSU2 — This connector is designated as the AC Connector for the redundant power
supply.
Installing the Frame Power Supply
The PS-OG3 is an auto-sensing supply, capable of working with all world AC standards (100-240V).
Each supply has an indicator LED on the front, and an error detection circuit that will indicate the
conditions.
The PS-OG3 power supplies install on the right and left sides of the OG3-FR series chassis.
To install the power supply
1. Carefully unpack the power supply from its box, and retain all packing material for
future use, if required.
2. Align the power supply into an unused power slot on the right side of the frame.
3. Push the power supply in firmly to ensure a tight connection at the rear of the frame.
