SW1: DUT Power Status LED on Interposer
This switch connects the DUT power Indication LEDs to the bus power. It is located near teh Lane Activity LEDS.
SW2: Clock Configuration Selection
The Host Type configuration used by the analyzer to record PCI Express traffic is configurable according to below table. DIP switches
and tables for the Host Type configuration are located on the front side of the interposer.

Note:
This switch connects the DUT power indication LEDs to the bus power. In some systems with
Hot-Plug management the Power Indication LEDs on the interposer may prevent the host system
from turning ON bus power to the device, if this happens disconnect the LEDs using SW1 to allow
proper bus power operation.

Pushbutton reset switch SW3 is used for NC-SI RBT
Interface PHY device reset.
Default position: Open
Pushbutton SW4 is used to turn off the terminations
and remove all loads on the unused interposer
receivers depending on the maximum number of
lanes to be analyzed. Press the pushbutton switch
(SW4) to move to the next active width as indicated
by the LEDs (next to the switch) on the interposer.
This is useful for devices that require terminations
not to be present in order to train to a lower link
width. The Active Width can be also controlled from
the PCIe Protocol Analysis.
Default position: x16
Note:
Even though the Active Width may be lower than
x16, it may be possible that the Signal Detect LEDs for
higher lanes are ON if those lanes are transmitting signal.
