LED Indications
ACCESS

Indicates the basic hardware status of the module.

  • Off—The module is not yet functional or has detected a problem with a PXI Express power rail.
  • Amber—The module is being accessed. Accessed means that you are writing to the device setup registers to control the device, reading from the device to monitor the device status, or transferring data to or from the device.
  • Green—The module is controllable through the software.
    • ACTIVE
  • Off—The module is idle or locked to the requested reference.
  • Solid red—The PLL is unlocked or the module temperature is out of the specified operating range.
