Danger:

•Make your chassis ground connections first (see Figure 2). If the chassis is not correctly grounded, excessive electromagnet emission may result.

•Disconnect all power to the equipment rack or cabinet before chassis installation.

•Never operate the E1200i system with empty RPM, SFM, or line card slots. Always replace empty slots with blank panels.

Each E1200i system requires at least two AC Power Supplies or at least one DC Power Supply to operate.

Three AC units are required for power supply redundancy, four AC units are required for full facility redundancy, and six AC units provide 3+3 redundancy

Two DC units are required for power supply and full facility redundancy.

Danger: Leakage Current (High Touch Current): The AC power cords are secured to the power inlet using the provided bracket. The AC power cord plugs must be secured to the building outlets by the chassis installer or a qualified electrician.

Refer to Appendix D, on page 91 for specifications on thermal output and other power related numbers.

Fans and Airflow

Your E1200i chassis contains two field-replaceable fan trays. Air flows through the system from a filtered-intake vent located in the lower part of the chassis. Air circulates from the bottom front (and sides) to the back and exhausts through a top rear vent. The variable fan speed is reduced at normal operating temperatures and increases to full speed as operating temperatures increase, up to 104° F (40° C).

For fan tray access, maintenance and proper ventilation, position the chassis and equipment rack or cabinet so that:

•At least three inches clearance is around the front and side intake and exhaust vents for free air flow

•Provide 20 inches in the rear to access the fan tray.

•Operate the E1200i system with two fan trays.

For instructions on replacing a fan tray, refer to Removing and Replacing Fan Trays on page 65.
