Diagnostics panel LEDs LED Description PS1 Power supply 1 failure. PS2 Power supply 2 failure. PS3 Power supply 3 failure. NON Non-redundant power. OVER Overspecification. The system has exceeded the power capabilities of the installed power supply units. NMI Non-maskable-interrupt occurred. TEMP System temperature exceeded maximum rating. FAN A fan failed or is operating slowly. MEM CPU Memory failure. One or more memory DIMMS have failed. Microprocessor failure. One or both microprocessors have failed. PCI 1 Error on primary PCI channel (A) or system board. PCI 2 Error on secondary PCI channel (B) or system board. VRM Error on voltage regulator module or on integrated voltage regulator. DASD1 The hot-swap disk drive backplane on SCSI channel A has failed. DASD2 Not used. Before you begin Before you begin to install options in your server, read the following information: v Become familiar with the safety and handling guidelines specified under "Working inside a server with power on" on page 47, "Handling static sensitive devices" on page 47, and read "Safety information" on page 152. These guidelines will help you work safely while working with your server or options. v You do not need to turn off the server to install or replace hot-swap power supplies, or hot-swap drives. v The orange color on components and labels in your server indicates hot-swap components. This means that you can install or remove the component while the system is running, provided that your system is configured to support this function. For complete details about installing or removing a hot-swap component, see the information provided in this chapter. 46 : Netfinity 5100 Type 8658 Models 11Y, 21Y, 31Y, 41Y, 51Y, 1RY, 2RY, 3RY, 4RY, 5RY
