The current power grid configuration is: Single gridPower grid configuration preference. 1. Single grid2. Dual grid Select Option: Figure 2-26 Distribution of Input Power for Each Bulk Power Supply WARNING! Voltage is present at various locations within the server whenever a power source is connected. This voltage is present even when the main power switch is in the off position. To completely remove power, all power cords must be removed from the server. Failure to observe this warning could result in personal injury or damage to equipment. CAUTION: Do not route data and power cables together in the same cable management arm. Do not route data and power cables in parallel paths in close proximity to each other. The suggested minimum distance between the data and power cables is 3 inches (7.62 cm). The power cord has current flowing through it, which creates a magnetic field. The potential to induce electromagnetic interference in the data cables exists, which can cause data corruption. NOTE: Label the AC power cords during the installation. One suggestion is to use tie wraps that have the flag molded into the tie wrap. The flag can be labeled using the appropriate two characters to represent the particular AC power input (for example, A0). Another suggestion would be to use color coded plastic bands. Use one color to represent the first pair A0/A1 and another color to represent the second pair B0/B1 (provided a second power source is available at the customer site). NOTE: System firmware will prevent boot when a single power cord configuration is detected. Installing The Line Cord Anchor (for rack mounted servers) The line cord anchor is attached to the rear of the server when rack mounted. It provides a method to secure the line cords to the server preventing accidental removal of the cords from the server.
