IMPORTANT:
Do not touch the terminals of the riser cards and PCI boards with
your bare hand. Fingerprints and dust left on them cause the server
to malfunction.
If you are unable to install a PCI board correctly, remove it, and then
install it again. Be careful not to apply excess force to a PCI board or
riser card. Doing so may damage the card.
NOTES:
Confirm that the slit in the PCI board bracket is positioned by the
embossed part. (This applies to other card brackets and extension
slot covers.)
Confirm that the top end of the PCI board bracket is inserted in the
designated slot of the riser card.
If a full-height PCI board is installed, confirm that the PCI board
bracket and the edge of the opposite card are inserted in the guide
rails of the riser card.
