PCI Adapter Dividers and Light Pipes
The following procedures describe the removal and replacement of PCI adapter dividers and light pipes.
Before performing the following procedures, read the "Safety Notices" on page ix.
Removing a PCI Adapter Divider
To remove a PCI adapter divider, do the following:
1. Stop the system as described in "Stopping the System" on page 246.
2. Place the system into the service position as described in "Placing the Model 275 into the Service and
Operating Position" on page 248.
3. Disconnect the power source to the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the system power source is completely disconnected.
4. Remove the service access cover as described in "Removing the Service Access Cover" on page 249.
See the following illustration.
5. Because the PCI adapter dividers are near to the PCI adapters, refer to "Handling Static-Sensitive
Devices" on page 244. If the PCI adapter divider you are removing has PCI adapters adjacent to it,
remove the adjacent PCI adapters as described in "Removing a Non-Hot-Pluggable PCI Adapter" on
page 253
6. Locate the PCI adapter divider you want to remove.
7. If you are removing a short adapter divider, continue to the next step. If you are removing a long
adapter divider, do the following:
a. Unlatch and open the PCI adapter light-pipe plate attached to the fan tray.
b. Note the guide grooves located toward the front of the system in the disk drive backplane for
correct alignment.
8. Lift the PCI adapter divider from the system.
9. If you are removing a long PCI adapter divider that contains light pipes, do the following:
a. Note the location of each light pipe.
b. Carefully remove the light pipes from the long PCI adapter divider.
