Symptom
Some early short PCI cards can be inserted into the Xserve's PCI slots, but they only partially fill the slot. Xserve will not turn on.
Solution
Inserting these cards may damage Xserve. Only use compatible PCI cards. If you do not know if the PCI card is compatible with Xserve, contact the card's manufacturer.
Important:- The Xserve works with both 32-bit and 64-bit PCI cards at 33 MHz and 66 MHz, but requires 3.3 V universal cards.
- Do not install PCI cards, unless the cards physically fit. Different generations of PCI cards have different keys or "notches" in different positions on the PCI connector. The Xserve PCI connector is shown in figure 1.

The PCI connector on different PCI cards may have more "notches" than the Xserve PCI connector has keys. Ensure the PCI connector on such cards has two "notches" that match the keys on the Xserve PCI connector and that the card otherwise fits length-wise.
