2. Open the system doors. 3. Disconnect the cooling fan power cable from the interposer board by pressing the release tab on the power cable connector. 4. Unscrew the retention pin from the chassis and lift the fan assembly out of the system chassis. 5. To replace an individual fan, perform the following steps: a. Separate the two halves of the fan assembly by pressing the locking tabs at each end of the assembly. b. Remove the faulty fan and disconnect it from the fan power wiring harness (see Figure 18). Figure 18. Removing the Fan Assembly 1 Cooling fans (3) 2 Fan bracket 3 Thumbscrew c. Install a new fan in the assembly and connect it to the fan power wiring harness. Ensure that the replacement fan is oriented the same way as the original fan. d. Join the two halves of the fan assembly. 6. Slide the fan assembly back into the system and reinstall the retention thumbscrew. 7. When reinstalling the fan, be careful to avoid pinching the system interface cables. 8. Connect the fan power wiring harness to the interposer board. 9. Close the system doors and reconnect the system to AC power. 10. Turn on the system. Power Supplies The system may contain one or two hot-pluggable power supplies. Hot-Pluggable Power Supply Figure 19. Hot-Pluggable Power Supply Removal 1 Latch 2 Power supply 3 Handle To remove a hot-pluggable power supply with the system operating, perform the following steps. NOTICE: See "Protecting Against Electrostatic Discharge" for information on protecting the system from electrostatic discharge. CAUTION: Avoid touching the card-edge connector on the back of the power supply. Wait 10 to 20 seconds after disconnecting the power supply from its slot connector before removing the power supply or coming into contact with its back card-edge connector. 1. Open the system doors. 2. Observe the status indicators on the back of each power supply. If the red (front) indicator lights up, replace that power supply. 3. If there is only one power supply in the system, turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. Disconnect only the faulty power supply from its electrical outlet. 4. Unplug the power cord from the faulty power supply. NOTICE: The power supply is heavy. Support it with both hands when installing or removing it. 5. Remove the power supply: a. The power supply is secured by a latch on the back panel of the system. b. Rotate the top of the power supply latch downward. 6. Grasp the handle on the top of the power supply and lift the power supply straight up from the system. 7. Lower the new power supply into the chassis. Ensure that the power supply is properly seated into its slot in the chassis. 8. Close the power supply latch. As the latch closes, notice that the power supply slides back in its slot to engage its back-panel connectors with the mating connector on the PSDB. NOTE: The power supply will not function until the latch is engaged. 9. Connect the AC power cable to the new power supply and route the cable through the strain-relief clip on the back panel. 10. Connect the free end of the AC power cable to an electrical outlet. 11. Observe the back panel of the power supply to verify that the green power indicator LED is lit and that the red failure LED is off. 12. Close the top doors. Power Supply Distribution Board Figure 20. Removing the Power Supply Distribution Board 1 Power connector P1 2 Thumbscrew 3 Power connector P3 4 Power connector P2 To remove the PSDB, perform the following steps. NOTICE: See "Protecting Against Electrostatic Discharge" for information on protecting the system from electrostatic discharge. 1. Turn off the system, including any attached peripherals, and disconnect the AC power cable(s) from its (their) power source. 2. Open the system doors. 3. Disconnect the AC power cable from the AC power receptacle on the back of each installed power supply, and rotate the top of the power supply latch downward. 4. Remove the fan assembly. 5. At the PSDB (see Figure 20), record the mating connector location and disconnect the 12-conductor power cable harness attached to the P3 connector. 6. Record the mating connector location and disconnect the 24-conductor power cable harness attached to the P1 connector on the PSDB. 7. Record the mating connector location and disconnect the 18-conductor power cable harness attached to the P2 connector on the PSDB. 8. Loosen the thumbscrew on the PSDB and remove the PSDB from the chassis. When installing the replacement PSDB, fold the cable harnesses out of the way as you are inserting the PSDB. The side of the PSDB with the card-edge connector that mates with the power supply connector should be lowered into position first; this simplifies installation of the PSDB. Expansion Cards The system has a removable expansion-card cage, which simplifies many installation procedures by allowing the user to remove the riser board and all installed expansion cards in a single step.
