Removing and Replacing a PCI Card

Replacing A PCI Card

NOTE The PCI I/O card installation process varies depending on which version of the HP-UX

operating system you are running on your system. PCI I/O card installation procedures should

be downloaded from the http://docs.hp.com/ Web site. Background information and procedures

for adding a new PCI I/O card using online addition are:

For HP-UX 11.11, consult the HP System Partitions Guide.

For HP-UX 11.23, consult the Interface Card OL* Support Guide.

Step 1. Visually inspect the replacement part for proper number and revision.

Consult the appropriate guide for instructions on preparing the operating system for online

addition of the PCI I/O card before attempting to insert a PCI I/O card into the PCI-X chassis

backplane.

Step 2. Position and seat the replacement PCI card in the slot.

NOTE A slow, firm pressure is needed to properly seat the card into the connection.

Step 3. Rotate the card slot PCI gate to the closed position.

NOTE The Server Expansion Unit implements manual retention latch (MRL) hardware for

use in online add or replacement (OLAR) operations. If an MRL is left open while the

server is booting, HP-UX can incorrectly cache PCI slot power status causing OLAR

operations to fail. To prevent this situation, ensure all the MRLs are closed before

booting the server.

If OLAR reports that a slot is present and powered off, but no OLAR operations to

turn power on to that slot have succeeded even after the MRL is closed, the MRL

may have been left open during boot. To clear this condition, close the MRL for the

PCI slot then power off the PCI slot using the rad -o command. This will allow

future OLAR operations to succeed on this PCI slot.

Step 4. Replace the top cover.

Step 5. Connect all cables to the replacement PCI card.
