CAUTION If you are using Linux Red Hat Advanced Server 2.1 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.
CAUTION Do not use more than 3 RAID cards in any of the slots on your HP Integrity rx4640 server.
Server power limitations restrict the use of more than 3 RAID cards per server.
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 does not initialize and powers down due to
frequency mismatch.
d. Incompatible-Bus: Card is rejected. The new card does not initialize and powers down due to bus mode
mismatch.
e. Maximum bus mode and frequency supported on shared slots is PCI-X 66 MHz.
