ADLINK PCIe-PXIe-8638 - Manual (Page 20)

10 Getting Started.
2.6 Power ON/OFF Sequence
To power-on the PCIe to PXIe Extension Kit:
1. Ensure that the extension cable is properly connected to
the host PC and PXIe chassis.
2. Power on the PXIe chassis.
3. When status LEDs of the PXI Express chassis and all
installed modules indicate ready, power on the host PC
.
As the PCIe to PXIe Extension Kit is equipped with a standard
PCIe switch, the BIOS will identify each device behind the switch
and assign resources to each during startup. Thus the PXI chassis
must be powered up in order to acquire appropriate resources
from the BIOS.
To power down the PCIe to PXIe Extension Kit:
1. Power down the host PC.
2. Power down the PXIe chassis.
CAUTION:
DO NOT remove the cable after the system and PXIe
chassis are powered on. Disconnecting the cable while
the system is running may cause unpredictable system
errors and/or system crash.
CAUTION:
DO NOT power down the PXIe chassis until the host PC
is powered off. If the PXIe chassis is powered off while
the host PC is on, the host PC may hang or crash.
