The chassis will not intentionally modify its operation because of conditions that
cause one or more LEDs to flash. In other words, the chassis will attempt to
continue normal operation despite flashing LED(s). However, a flashing LED may
indicate a condition that will prevent the chassis from operating correctly. For
example, a flashing Fan LED indicates that one or more rear panel fans are under
speed, which may cause the temperature of the chassis to rise and exceed
specifications. This, in turn, may cause a thermal shutdown of the power supply.
Therefore, flashing LEDs should be tended to promptly. See the
Keysight PXIe
for further information.

PC startup requirements for Keysight IO Libraries Suite
This section describes the PC startup events for Keysight IO Libraries Suite.
Improvements have been made in Keysight IO Libraries Suite that considerably
simplify the PC startup process. Keysight recommends use of latest version
Keysight IO Libraries Suit.
Before describing the PC startup events for each version, two situations are
described where Connection Expert, which is part of Keysight IO Libraries Suite, will
not display a PCIe device, be it the chassis or a module in the chassis.
If Windows can not find a driver for a device, Windows will not be able to
identify the device and therefore Connection Expert will not be able to
display it. If this occurs, you will typically be presented with the
Windows
Wizard, which will give you the opportunity to assist
New Hardware Found
Windows in finding a driver. If a driver is found, you should restart the PC
and verify that Windows identifies the device (which will be evident by the
lack of the
Wizard for that device).
New Hardware Found
The other situation where Connection Expert will not display a PCIe device is
in the event that, when Connection Expert is started, Windows has not yet
completed assigning drivers to the devices (the chassis or modules in the
chassis) found during enumeration. Connection Expert will not display
modules that it cannot identify. In this situation, however, the driver exists
but it has not yet been assigned to the device by the time Connection Expert
is started.
This situation should be very rare; if it occurs, it would be expected to occur with
slower PCs. The solution for this situation depends on which version of IO Libraries
Suite you have installed and is described below. For the first-ever connection of the
chassis to the PC, or after changing the chassis configuration, only a single boot of
the PC is needed. However, sufficient time needs to be allowed between when
Windows is up and when Keysight Connection is started in the following figure.
