1INTRODUCTION
The Silicom PE10G8TS81 TimeSync Adapter STS2 is a 1/10 Gigabit Ethernet PCI Express Gen4
TimeSync server adapter, designed for X86 Servers and high-end appliances.
The 1/10 Gigabit Ethernet TimeSync PCIe server adapter is based on the Intel E810 chipset and best in
the industry timing solution targeting 5G/Class C wireless base stations and carrier-grade systems.
The Silicom STS2 provides support to synchronize the host system from any of the eight 1G/10G ports
or from an external 1PPS or 10MHz. The STS2 TimeSync server adapter supports both 1588v2/PTP
and SyncE for high clock accuracy in PTP Master and PTP Slave modes. The design conforms with O-
RAN requirements for LLS-C1, LLS-C2 and LLS-C3 (O-RAN-WG4-CUS.0-v04.00) operation modes
with both Boundary and Transparent clocks.
The Silicom STS2 supports:
•IEEE1588v2/PTP over IPv4, IPV6, and Ethernet
•PTP profiles ITU-T G.8275.1 and ITU-T G.8275.2
•SyncE /ITU-T G.8262
•T-BC Boundary Clock and T-TSC Slave Clock / ITU-T G.8273.2
•T-GM Grand Master /G.8273.1
•PRTC Primary Reference Time Clock Class B/G.8272
•T-TC Transparent Clock /G.8273.3
•1588 Software Stack and Servo Software in x86

4. Push the card downwards into the slot. Apply moderate pressure until the card “clicks” into
place and sits snugly in the slot.
5. Ensure the card connectors align with the slot’s back panel aperture and secure the card with
a screw.

Note: Route the cables in such a way as to prevent damage during system operation. Keep the cables away
from sharp edges and use plastic cable ties to secure them properly.
See Appendix B for further insertion/extraction guidance and precautions of RF cables.

2. Connect the USB cable:
•Connect the connector to F on the STS card.
•Connect the USB connector to a USB port on the host computer.

3IDENTIFYING THE CARD IN THE LINUX SYSTEM
After installing the card and powering up the system, verify that the card is identified by the system.
1. Run lsusb to view the device location on the USB bus:
(note the below is example of what you can get, need to see that you have the two lines in RED)
The output should include the two lines in the red box.
2. Run lspci -nnv | grep 02d8 to view device details on the PCI bus.
The output should include these eight lines, one for each 10G port on the device.

5APPENDIX B: Usage Precautions OF RF Cables
Note: RF cable connector is sensitive and extra precaution required to mate the connectors.
Insertion:
•To mate a connector, place the plug connector above the receptable connector, the mating axes of
both the connector plug on cable and the receptable connector on board must be aligned together to
allow connectors mating.
•Use your finger or available tool with flat surface to press vertically the plug connector gently onto
the receptable connector.
•Once connector has been mated a "click" sound will confirm fully mated connection.
•See below link to a video that shows proper connection process
https://youtu.be/8wGxuiWoBvo
•Route the cable in a way that no damage will occur during system operation. Keep the cables away
from sharp edges, moving parts, and use plastic cable ties to secure them properly.
•Pay attention: once the connectors were
mated - do not apply excess forces than
indicated at the diagram on the right.
•Do NOT forcefully twist or deform cable as
it may stress the connector.

Silicom TimeSync Hardware Installation Guide
Page 15 of 16
Extraction:
•Improper extraction can subject the plug and receptacle to uneven twisting or wrenching motions
which can result in damage to the connectors.
•To disconnect a connector, use your nails or end portion of ”L” shape available tool, locate it under
the connector flanges and pull off vertically. Alternately you can hold the connector lid and pull off
vertically.
•Do not pull the cable in order to disconnect a connector- it may damage the cable or the connector.
Note: Be careful not to damage the connector with your fingers or nails.
