Installing the Chassis | 174Installing the ChassisSafety ConsiderationsWARNING: The E300 System is packaged in two separate containers. The chassis container measures 25.5”x 31” x 28” and weighs approximately 135 pounds. The board container measures 24” x 34.5” x 26.5” andweighs approximately 90 pounds. Use an equipment lift or pallet jack to install or lift the chassis. Lifting thechassis by its shelves or fan try opening will cause chassis damage.NOTE: If you are installing the chassis without using a equipment lift or pallet jack, remove all AC powersupplies, the fan tray, line cards, RPMs and SFMs from the chassis prior to lifting it.Installing the Chassis into an Equipment RackEnsure there is a minimum of six inches of clearance between the side intake and exhaust vents and anywalls. If you are installing two E300s next to each other or an E300 next to another side-by-side airflowchassis, position the chassis at least 12 inches apart.Prior to installing the E300 in an equipment rack, you must install the equipment rack bar. This barenables you to easily position the chassis into the rack and stabilizes the chassis.Figure 4-1. Installing the Equipment Rack BarTo install the chassis into a 19-inch equipment rack, using the front mounting brackets, follow thesesteps:Step Task1 At the desired location in the rack, orient the equipment rack bar with the arrows pointing up. The smooth side ofthe bar should face outward.2 Using the mounting screws provided with your rack, attach the bar to the rack (see Figure 4-1).3 Using a hand cart, pallet jack, or forklift, align the rack-mount holes with the equipment rack holes, situating thechassis on top of the equipment rack bar.FN
