Comments
• Pull the carrier handle out fully before inserting the carrier in
the I/O boat slot. The PCI card and carrier plate will strike the
card socket if the handle is not fully retracted.
• The carrier is not correctly seated in the upper or lower card
guide.
• A type C lock is in the wrong location and is hitting the card
socket.
• The PCI card is not mounted correctly on the carrier. If the PCI
card is tilted by even a small angle on the carrier, it might not
seat correctly.
• The PCI card does not fit the socket. The card might be the
incorrect type for the I/O boat. (Note that the PCI-X card
socket is approximately twice the length of a PCI Express
socket.)
• The PCI Express boat does not accept x16 PCI Express cards.
This boat accepts only x8 PCI Express cards or smaller.
shorten the troubleshooting process. If you cannot determine if
a link problem is caused by a link card or a link cable, order
replacement link cards for the host and the I/O boat, along
with a copper link cable or two optical link cables, as
appropriate.
• The host PCI Express slot containing the link card must be
powered on. The host service processor communicates with I
devices in the External I/O Expansion Unit through the link
cards and cable. Verify that the domain is powered on and that
the link card in the host slot is fully seated.
• If the host link card is added to a running domain, see
Section 4.13, "Powering Up a Link After Service" on page 4-32
to power on the PCI Express slot.
