1. A be between and 10 megohms Tools Required You need the following tools to install or replace a power supply A 1 4 inch flat blade screwdriver and a number 2 phillips screwdriver Small wire cutter If the chassis is mounted in an equipment rack and cables from other equipment fall in front of the power supply bays you will need cable ties to temporarily anchor the cables out of the way If access to the power supply bays is partially blocked by a power strip or other permanent rack fixture you will need a 1 4 inch flat blade screwdriver to temporarily detach the ears from the equipment rack mounting strips ESD preventive wrist strap Before beginning the power supply installation check the installation screws on all power supplies and check the area around the power supply bays to determine which tools you will need The new or replacement power supply and the power cable that you supply are the only parts you need to complete this installation If you remove a power supply and leave the bay empty install a cover plate over the empty bay The chassis is shipped with a cover plate installed over the empty bay Circuit Protection Requirements Based on the NFPA 70 National Electrical Code you should use a 35A overcurrent protector to meet the requirement for the overcurrent protector size of 125 percent of the load current which is approximately 27A An overcurrent protector rated for 30A can be used only if it h2. flashes at power on for a lamp test Figure 3 Power Supply LEDs The OUTPUT FAIL LED lights for either of the following reasons Power supply DC output failure which might be caused by an overload by the system or an actual failure in the AC input power Power shutdown that is initiated by the power supply because it detected an out of tolerance voltage condition in the power supply 4 1200 Watt AC Input Power Supply Replacement Instructions Environmental Monitoring and Reporting Functions In systems with a single power supply and in systems with redundant power when both power supplies are shutting down the OUTPUT FAIL LED lights momentarily as the system powers down but goes out when the power supply has completely shut down Safety Interlock Mechanism The power supplies feature the following three safety interlock features An on off switch with a locking mechanism see Figure 4 that prevents the power supply from being removed from the chassis when the power supply switch is in the on I position When the switch is on a metal tab extends into a slot in the chassis When the switch is in the off O position the tab is raised and clears the slot Figure 4 On Off Switch Locking Mechanism Acaptive installation screw at the bottom of the power supply front panel provides electrical grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging from the power connectors in the backp
