Installing the Power Cord Retaining Clips
Each power supply is provided with a power cord retaining
clip that holds the power cord in place to prevent inadver-
tent disconnections.
To install the power cord retaining clips
1 With the power cord removed, install the clip into the
plate that extends out beneath the power cord
socket on the rear of the frame, by slipping the two
ends of the clip into a pair of holes in the plate
Several pairs of holes are provided to accommodate
different sizes of plugs. Use the holes that position
the clip closest to the body of the plug.
2 Position the clip horizontally and insert the plug into
the socket.
3 Rotate the clip up and press the cord into the gripping loop of the clip.
Ventilation
Ventilation for the frame is provided by two fan assemblies, each containing three fans, located
on each side in the top section of the rear panel. The fans draw air through the frame from the
front and exhaust it to the rear. Ventilation slots are provided in the front door of the frame to
allow air to flow into the frame.
An air filter is installed in the front door behind the slots.
• Ensure that the front door ventilation slots are not obstructed.
• Check the air filter regularly to ensure that it is not plugged up with debris.
See Cleaning and replacing the front-door air filter , on page 44 for detailed instructions.
In addition to the main frame cooling fans, each installed power supply has its own fans that
pull air into the front of the supply. The fan speed is controlled in response to overall load and
frame temperature.
