For PCI OL* information, see the Interface Card OL* Support Guide. For PCI OL* information on nPartition-able systems, see the nPartition Administrator's Guide.

PCI OL*, previously known as OLAR, is the ability to add or remove a PCI card without needing to completely shutdown the entire system. The system hardware combined with operating system support allows per-slot power control. Instead of turning off the entire system, you can turn off and on power to a specific PCI slot.

The procedures for PCI OL* can be performed through the Peripheral Devices section of HP SMH, pdweb, or the Partition Manager for nPartition-able systems, or through HP-UX commands, such as olrad. All are documented in the preceding documents.

	CAUTION: Before attempting these procedures, please read the documents mentioned above. Turning off power to certain PCI slots can have disastrous effects; for example, if the PCI slot connects to an unmirrored root or swap disk, the system will crash. Further, the I/O card itself needs to be checked for OL* functional compatibility as well as compatibility to the specific PCI slot; for example, you cannot insert a 33 MHz card in a slot running a 66 MHz bus.

For general peripherals, see Interface Card OL* Support Guide.

See the HP-UX 11i Release Notes for the titles of documents that may be relevant to installing peripherals. Such documents may contain specific information on the software driver and the device special file for communication with particular peripherals.
