Note: You might need to remove the diskette drive from the server in order to disconnect and reconnect its cables. The diskette drive is held in the server by release tabs that are accessed by removing the server front bezel. b. Connect the P5 device power connector to the back of the CD-ROM drive. c. Connect the other device power connectors (P4 and P6) to the rear of any other devices in the server. d. Connect the SCSI cable (P2) to the SCSI backplane. e. Connect the power cable (P1) to the J4 connector on the system board. f. Connect the power signal cable (P3) to the J10 connector on the system board. g. If your server has the 3-Pack Ultra320 Hot-Swap Expansion option installed, connect the power connector (P8) to the power connector on the 3-Pack backplane. 8. Reinstall the adapter-support bracket. See "Removing and installing the adapter-support bracket" on page 58 for instructions. 9. Replace the server cover (see "Installing the server bezel and left-side cover (tower model)" on page 100 or "Installing the server bezel and top cover (rack configuration)" on page 103. 10. Plug one end of each power cord into the corresponding connector on the power supply; then, plug the other end of each power cord into a properly grounded electrical outlet. Note: You can route the power cords through the power-cord restraint bracket on the rear of the server (tower model only). 11. If the server is not on, turn on the server. 12. Verify that the dc power LED and the ac power LED on each power supply are lit, indicating that the power supply is operating properly. Replacing a hot-swap fan Your server comes with six hot-swap fans: two front fans (fans 5 and 6), two center fans (fans 3 and 4), and two rear fans (fans 1 and 2). The two front fans are also known as blowers. You do not need to turn off the power to the server to replace a hot-swap fan. Attention: To help ensure proper cooling, if a fan fails, replace it within 48 hours. The following illustration shows how to replace hot-swap fans. 94 xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
