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 a PCI board is installed in a slot lower than the one containing the 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.
