Power LED errors Use the power supply LED information on the following page to troubleshoot power supply problems. Note: The minimum configuration required for the DC Good light to come on is: v Power supply v Top power board v AC power box v Power cord and cables Note: See Chapter 8, "Parts listing, Type 8870," on page 249 to determine which components are replaceable by the customer, and which components should be replaced by an IBM field service technician. AC good LED DC good LED Front Power good power on indicators light (center plane) Description FRU/action Off Off Off Off No power to system or ac problem. 1. Check ac power to system. 2. Isolate by removing one power supply at a time. 3. Unplug the three power connectors to center plane (J11, J19, J23). a. Inspect cables. b. Top power board. On Off Off Off DC source power problem 1. View service processor error logs through serial connection of remote supervisor adapter. 2. Isolate with single SMP Expansion Module. 3. Unplug the three power connectors to the center plane (J11, J19, J23): a. If dc LED lights, go to step 4. b. If dc LED does not light: 1) Power supply. 2) Top power board. 4. Reconnect the three power connectors to the center plane; then, isolate the failing FRU by disconnecting: v Center plane light path cable and SCSI power cable (J8, J9) v PCI adapters v Fans 1 and 2 v I/O board cable attachments (J1, J2, J3, J8) (see "I/O board internal connectors" on page 166) 5. If no LEDs are lit after step 4, replace the following: a. Center plane VRM b. Center plane c. PCI-X board and VRM d. I/O board and VRM e.
