Removing and Replacing Hot-Plug PCI-X Cards

•Slots 7 and 8 are single slots, they do not share a PCI-X bus. The maximum capability of each slot is PCI-X 133 MHz. Only slots 7 and 8 allow 133 Mhz, PCI-X cards to run at full speed. These two slots are not limited by bus mode frequency related incompatibilities.

a.The conditions described in this table apply only to shared slots (slots 3,4-bus 2 and 5,6-bus 3). Slots 7 and 8 are not shared slots.

b.Compatible: card is accepted and runs at frequency shown.

c.Incompatible-Frequency: card is rejected. The new card will not initialized and will power down due to frequency mismatch.

d.Incompatible-Bus: Card is rejected. The new card will not initialize and will power down due to bus mode mismatch.

e.Maximum bus mode and frequency supported on shared slots is PCI-X 66 MHz.

CAUTION If you are using Linux Red Hat Enterprise Advanced Server 4 Update 3 operating system and you want to install a 1000b-Sx GigE card, do not install it into a slot that shares a bus with a 33 MHz card. In this configuration the Linux driver will not initialize the new card.
