Step Task 3 For bottom units, ensure that the EMI gasket along the edge of each power supply is compressed smoothly before securing each power supply into place using the captive screws. For top units, it may be necessary to lift the unit slightly to install the captive screws. As a best practise, insert the two captive screws of each power supply by hand before tightening them all. CAUTION: Tighten the screws with a #2 Phillips screwdriver. Use no more than eight pounds of torque (light torque with a manual screwdriver). Too much torque can damage fasteners and that improper use of power drivers can cause even greater damage. 4 Plug the AC power cord into the AC power inlet in the face of the power supply. 5 Plug the AC power cord into an AC power outlet. 6 Toggle the standby switch of the power supply to the On position. NOTE: Power modules are not field serviceable. E300 DC Power Modules The E300 supports a minimum of one DC PEM. You must have only one type of power module in the chassis; you cannot install a mixture of power modules. You must provide your own cables to connect to a remote power source (a circuit breaker panel, for example) in your equipment rack or facility. Cables must be sized to meet the following criteria: • Rated for 60A service to allow for a fully loaded E300 system per NEC in the United States or internationally, per local safety codes. • Limit voltage drop across the cable length to 0.5V or less. Before you make the cable connections, apply a coat of anti-oxidant paste to unplated metal contact surfaces. File unplated connectors, braided straps, and bus bars to a shiny finish. It is not necessary to file and coat tinned, solderplated, or silver-plated connectors or other plated connection surfaces, such as those on the PEM studs. Installing the Hardware 13
