Site Preparation | 17WARNING: The E1200i AC Chassis is shipped with two tool-accessible covers preventing access into thealternative DC PEM cavities. Do not remove these covers; they prevent unauthorized access to high directcurrent locations within the chassis. The covers must remain in place at all times.WARNING: Make your chassis ground connections first (see Figure 2-2). If the chassis is not correctlygrounded, excessive electromagnetic emission may result.WARNING: Disconnect all power to the equipment rack or cabinet before chassis installation.WARNING: Never operate the E1200 system with empty RPM, SFM3, or line card slots. Always replaceempty slots with blank panels.Each E1200 system requires at least three AC Power Supplies or at least one DC Power Supply to operate.Three AC units are required for power supply redundancy, and so six AC units provides full redundancy.Two DC units are required for power supply and full facility redundancy.WARNING: Leakage Current (High Touch Current): The AC power cords are secured to the power inlet usingthe provided bracket. The AC power cord plugs must be secured to the building outlets by the chassis installeror a qualified electrician.Refer to Chapter C, System Specifications for specifications on thermal output and other power relatednumbers.Fans and AirflowYour E1200 chassis contains two field-replaceable fan trays. Air flows through the system from afiltered-intake vent located in the lower part of the chassis. Air circulates from the bottom front (andsides) to the back and exhausts through a top rear vent. The variable fan speed is reduced at normaloperating 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 orcabinet so that:• at least three inches clearance is around the front and side intake and exhaust vents for free air flow• 20 inches in the rear are available to access the fan tray• the system can operate with two fan trays.For instructions on replacing a fan tray, refer to Removing and Replacing Fan Trays.Storing ComponentsCAUTION: Do not transport a chassis with components (line cards, power supplies, RPMs, Fan Trays, PowerSupply, or SFM3s) installed in the chassis. Place the modules in their original ESD-preventative packagingand attach the Front Shipping Cover on the front of the chassis prior to placing the chassis in its originalshipping crate. Shipping the chassis with components installed may damage the components and the chassisbackplane.If you do not install your E1200 system and components right away, properly store components and allextra field-replaceable components (spares) until you are ready to install them. Keep all components inthe original packaging during storage.Follow these indoor storage guidelines:• Storage temperature should remain constant ranging from -40° to 158°F (-40° to 70°C).
