Power Supply PS-8300 and Power Cable
The DFR-8300 series frame comes standard with one PS-8300 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 DFR-8300 series
frame. One A/C power cable has been provided with each power supply ordered.
Notice — To improve performance and reliability, the PS-8300 has an on-board
fan. Under high load conditions (>40W), the optional CFM-8310 Cooling Fan Module
must be added for increased ventilation.
For further redundancy, each power cord should be connected to a separate power source for protection
against failure of the A/C power circuit. Reliability will also be improved when using redundant
supplies as each supply shares the load. 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.
Power Supply Connectors (PSU1, PSU2)
There are two power supply connectors located on the back of the DFR-8300 series 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 power supply plugs into the right-hand section of the chassis. The universal power supply supports
all worldwide AC power voltages, and no power adjustments are required. The secondary (redundant)
power supply, if ordered, is already installed in the frame.
Use the following procedure 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.
The PS-8300 is a power factor corrected supply, capable of working with all world AC standards (100-
240V). The supply has an indicator LED on the front, and an error detection circuit that will indicate
the conditions described in Table 2.2.
