Expansion boards
The server supports PCI-X, PCI Express, and hot-plug PCI-X expansion boards. For location, refer to Rear
Panel Components (on page 10).
Slot Expansion card type Capable speed
1 PCI-X, non-hot-plug
100 MHz* (slots 1 and 2 share the
same bus)
2 PCI-X, non-hot-plug
100 MHz* (slots 1 and 2 share the
same bus)
3 PCI-X, non-hot-plug
100 MHz* (slots 3 and 4 share the
same bus)
4 PCI-X, non-hot-plug
100 MHz* (slots 3 and 4 share the
same bus)
5 PCI Express x4
6 PCI Express x4
7 PCI Express x4
8 PCI Express x4
9 Hot-plug PCI-X 133 MHz
10 Hot-plug PCI-X 133 MHz
*HP recommends that cards with speeds of at least 100 MHz be installed in these slots. If cards with lower bus
speeds are installed, the bus speed will be reduced. However, server performance will not suffer if the speed on one
bus is slower than the speed on a different bus.
Removing an expansion slot cover
1. Power down the server (on page 27).
2. Extend or remove the server from the rack ("Extending the server from the rack" on page 27).
3. Remove the access panel ("Access panel" on page 31).
4. Remove the expansion slot cover.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all PCI slots
have either an expansion slot cover or an expansion board installed.
