2.4.2 LEDs
When powered on, the Summit Z3‐16 Exerciser activates user accessible LEDs on the back
of the card.
TRAIN (training) LEDs
There is a TRAIN LED indicating whether the link is TRAINED or not.
Transmitter and Receiver LEDs
There are 32 LEDs, 16 for Transmitting and 16 for Receiving. These LEDs light up in two
colors displaying transmitting or receiving activity.
 Green ‐ no errors on the lane
 Yellow ‐ the Summit Z3‐16 Exerciser detects errors on this lane
2.4.3 Bus LEDs
There are 3 LEDs indicating the operating speed of 2.5/5.0/8.0 GT/s which is Gen1, Gen2
and Gen3 bus speed.
2.5 PCI Express Test Platform 16x2.5GT/s / 16x5.0GT/s / 16x8.0GT/s
The PCI Express Test Platform 16x2.5GT/s / 16x5.0GT/s / 16x8.0GT/s (see Figure 2.3 on
page 20 ) for the Summit Z3‐16 Protocol Exerciser can be purchased optionally to allow
the Summit Z3‐16 Exerciser to act as a host machine, enabling extensive protocol level
testing of PCIe devices. It provides a convenient, powerful and flexible PCI Express Test
Platform for PCI Express devices at data rates up to 8 GT/s and lane widths up to x16. It
has two PCIe slots, one dedicated to the Summit Z3‐16 Exerciser and another for the
Device Under Test. The Summit Z3‐16 Exerciser can be conveniently powered by the PCI
Express Test Platform using a special power cable, which eliminates the need for an AC
power adapter. When purchased with the Summit Z3‐16 Exerciser it provides power to
the Summit Z3‐16 Exerciser. The PCI Express Test Platform has a DUT PCIe x16 slot to
capture protocol traffic between systems.
In addition, there is a complete Gen3 protocol analyzer interposer built into the platform
to enable connectivity with a PCIe analyzer such as the Summit T3 to monitor exerciser
traffic.
When the PCI Express Test Platform is powered on it provides power to the DUT slot and
the Summit Z3 slot. When using the PCI Express Test Platform you can choose a generic
internal reference clock or external reference clocking from an external source.
