Upgrading Your Server 7-39
Notes
Observe the following notes on installing/removing a PCI board:
!
Do not touch the terminals of the riser cards and the leads of electronic components with
your bare hand. Fingerprints and dust left on them cause the server to malfunction due to
a connection failure or damage to the leads.
!
A riser card is designed for installing only low-profile PCI boards or full-height PCI
boards. Before installing a PCI board, make sure of the card specification.
!
If the AcceleRAID 160 disk array controller is installed on the riser card of the low-
profile type, the internal hard disk drives cannot be used in a disk array configuration.
(Attach the provided bracket to the disk array controller, and install the controller on the
riser card of the full-length/full-height type.)
!
If a PCI board is installed in a slot lower than the one containing the N8103-52F disk
array controller, the LED relay cable provided with the server cannot be used to connect
the LED connector on the disk array controller board and the DAC LED connector on
the system board. (The disk access lamps on the front of the server cannot indicate the
status of access to the hard disk drives connected with the disk array controller.)
!
The PCI bus slot search order at start of the server is defined as follows:
– Low-profile riser card, and then the full-height riser card
– Ascending order of the slot numbers
Thus, the system searches for the slot numbers in the following order:
1C → 2C → 3C → 1B → 2B → 3B
A SCSI controller (including a disk array controller) with the system disk connected
must be searched for before any other SCSI controllers. Determine the slot in which the
SCSI controller is first searched for. The system is unable to start if the SCSI controller
search order is wrong.
!
Set "Disabled" for the optional ROM of a LAN device not to be booted by using the
BIOS setup utility.
!
If an additional LAN device is installed in slot 3C or 3B, it is hard to push the catch of
the connector with your finger that is connected to the LAN port. Disconnect the
connector pushing the catch with a standard screwdriver. At this time, be very careful for
the screwdriver not to damage the LAN port or other ports.
!
If a bootable PCI board (e.g., a disk array controller, SCSI controller, or LAN card) is
additionally installed, the boot priority is changed to the default. After the additional
installation, start the BIOS setup utility, select [Boot] → [Boot Device Priority], and set
the new boot priority.
!
If a disk array controller is installed on both the low-profile riser card and the full-height
riser card, the system is unable to start through a disk which is connected to the disk
array controller installed on the full-height riser card.
!
The SCSI controller installed on the low-profile riser card cannot be connected to a
device additionally installed in the internal backup device bay.
