See page 69 for the location of the PCI expansion slots on the system board.
Note: The illustrations in this document might differ slightly from your hardware.
Adapter considerations: Before you install any adapters:
v Determine which expansion slot you will use for the adapter.
– The second IBM FAStT Host Adapter (Fibre Channel) must be installed in slot
4, a 64-bit PCI slot.
– The first IBM Gigabit Ethernet Server Adapter must be installed in slot 3. If
you are installing a second IBM Gigabit Ethernet Server Adapter, it must be
installed in slot 4. Both slot 3 and slot 4 are 64-bit PCI slots.
– An IBM 10/100 Ethernet Server Adapter can be installed in any open PCI slot
(either a 32-bit or a 64-bit PCI slot).
®
– The Netfinity Advanced System Manager PCI Adapter must be installed in
PCI slot 1, a 32-bit PCI slot.
For more information about determining which PCI slot to use, see "Appendix C.
PCI Adapter Placement" on page 131.
