4-24 Upgrading Your System
Notes
Observe the following notes when installing/removing a PCI board:
!
Do not touch the fingers of the riser cards or the leads of electronic
components mounted on the cards. Fingerprints and dust left on them
may 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
type.
!
If a PCI board is installed in a slot below the slot containing the
AcceleRAID 160 disk array controller, the LED relay cable cannot be
used to connect the LED connector on the disk array controller board and
the DAC LED connector on the system board. In this case 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 system searches for the PCI board in the following order (See Figure
4-23):
PCI Slot 1B
→ → → →
2B
→ → → →
3B
→ → → →
1C
→ → → →
2C
→ → → →
3C
Note, however, if an AcceleRAID 160 or AcceleRAID 352 disk array
controller is installed, the system detects the boot device in the following
order.
PCI Slot 3C
→ → → →
2C
→ → → →
1C
→ → → →
3B
→ → → →
2B
→ → → →
1B
See "Disk Array Controller Board" in this chapter.
!
The PCI devices of the same type (including onboard PCI device) may be
recognized in different order from that described above, depending on OS
or disk array BIOS utility. Check the slot location of the PCI device by
PCI bus number, device number and function number shown in the table
below.
