HP Kayak XU Series 03xx and HP Kayak XW Series U3, W3 Identifying the LAN/SCSI Combination Board On the HP Kayak XU Series 03xx PC Workstation with the LAN/SCSI, one of two types of the HP 10/100 SCSI/LAN combination board are installed. Both LAN/SCSI combination boards have the same functionalities, but there are some minor differences. Due to this reason, when replacing one board by another (refer to the note on page 18), caution should be taken to ensure you have the correct board. Most HP Kayak XU Series 03xx models introduced around 07/98 (CPL) and 3 08/98 were preinstalled with the LAN/SCSI combination board (part number 5064-3616) that included one internal wide SCSI connector. A specific wide-to- narrow converter is required to enable a connection between the narrow 8-bit SCSI cable and the LAN/SCSI board. Also, this board does not include a Wake On Lan (WOL) connector. For the Remote Power On (RPO) feature to work, the ExtStart cable is used to connect between the External Start connector on the SCSI/LAN combination board and the HP External Start connector on the system board. While, on the most recently introduced Kayak XU Series 03xx, the SCSI/LAN combination board (part number 5064-6016), includes two internal SCSI connectors, one narrow SCSI connector and one wide SCSI connector. However, it should be noted that you should not connect any devices to the Internal Narrow SCSI connector and to the Internal Wide connector at the same time. If you do, this results in a badly "terminated" SCSI bus. Only an Internal Narrow SCSI cable is provided with the HP Kayak XU Series 03xx models. The SCSI/LAN combination board also includes a WOL connector. The RPO feature is now made available through the WOL connector, and no longer through the HP External Start connector. The HP External Start connector is still used to report LAN activity and SCSI hard disk drive accesses to the front panel status panel LEDs. How to Identify Which LAN/SCSI Board is Installed To identify which board is installed, you have to check the board for the above mentioned differences. To do that: 1 Shut down the PC Workstation, turn off the computer and disconnect the power cable. Remove the cover. 2 Check the part number: 5064-6016 - Includes two internal SCSI connectors (wide and narrow) and a WOL connector. 5064-3616 - Includes one internal SCSI connector. The WOL connector is not available on this board. If replacing one LAN/SCSI combination board model by the other model, refer to the note on page 18, for instructions.
