Upgrading Your Server 9-45NotesObserve the following notes on installing/removing a PCI board: Do not touch the terminals of the riser cards and the leads of electronic components withyour bare hand. Fingerprints and dust left on them cause the server to malfunction due to aconnection failure or damage to the leads. A riser card is designed for installing only low-profile PCI boards or full-height PCIboards. Before installing a PCI board, make sure of the card specification. PCI slot number "1C" is assigned to the riser card for low-profile PCI boards, and "1B" isassigned to the riser card for full-height PCI boards. The system detects the boot devices in order of the PCI bus slots 1B (full-height PCIboard) and then 1C (low-profile PCI board). The PCI devices of the same type (including onboard PCI device) may be recognized indifferent order from that described above, depending on OS or disk array BIOS utility.Check the slot location of PCI device by PCI bus number, device number and functionnumber shown in the table below.Bus number Device number Function numberOnboard NIC1 C 0 0Onboard NIC2 C 0 1Onboard HDD D 5 0Slot 1C 18 0 XSlot 1B* D 3 X* On certain PCI devices, other bus number may be assigned.. Set "Disabled" for the optional ROM of a LAN device not to be booted by using the BIOSSETUP utility. If an additional LAN device is installed, it is hard to push the catch of the connector withyour finger that is connected to the LAN port. Disconnect the connector pushing the catchwith a standard screwdriver. At this time, be very careful for the screwdriver not todamage the LAN port or other ports. If a bootable PCI board (e.g., a disk array controller, SCSI controller, or LAN card) isadditionally installed, the boot priority is changed. After the additional installation, startthe BIOS SETUP utility, select [Boot] and set the new boot priority. Contact your service representative for the acceptable optional PCI board.
