# Step 5: Connect your Outposts server to your network
<a name="install-network"></a>

To complete the network setup, you connect the server to your upstream networking device with network cable. 

Consider the following information about connecting to the network:
+ The server requires connections for two types of traffic: service link traffic and local network interface (LNI) link traffic. The instructions in the following section describe which ports to use on the server to segment traffic. Consult with your IT group to determine which port on your upstream networking device should carry each type of traffic.
+ Ensure the server has connected to your upstream networking device and has been assigned an IP address. For more information, see [Server IP address assignment](https://docs.aws.amazon.com/outposts/latest/server-userguide/local-server.html#lni-address) in the *AWS Outposts User guide for servers*.
+ The optical connection on an AWS Outposts server only supports 10 Gbits and does not support auto-negotiation of port speed. If the host port tries to negotiate port speed, for example, between 10 through 25 Gbits, you can run into problems. In such cases, we recommend you do the following:
  + Set the port speed on the switch port to 10 Gbits.
  + Work with your switch vendor to support a static configuration.

# Configure the QSFP network for your Outposts server

With the QSFP breakout cable, you use breakouts to segment traffic.

The following image shows the QSFP breakout cable:

![\[An image of a QSFP cable showing both ends.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/QSFPcable-both-ends.jpg)


**Note**  
AWS Outposts servers have a physical RJ45 port beside the QSFP port. However, this RJ45 port is not enabled for any customer use. If you require RJ45 1GbE connectivity, use the included QSFP cable to connect a 10GBASE-X SFP\$1 to a 1GbE RJ45 media converter.

One end of the QSFP cable has a single connector. Connect this end to the server.

The following image shows the end of the cable with the single connector:

![\[An image of a QSFP cable showing the single connector.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/QSFP-single-end.jpg)


The other end of the QSFP cable has 4 breakout cables labeled 1 through 4. Use the cable labeled 1 for LNI link traffic and the cable labeled 2 for service link traffic.

The following image shows the end of the cable with the 4 breakout cables:

**To connect the server to the network with the QSFP breakout cable**

1. Locate the QSFP breakout cable that came with the server.

1. Connect the single end of the QSFP breakout cable to the QSFP port on the server.

   1. Locate the QSFP port.

      The following image shows the location of the QSFP port on the 2U server.  
![\[An image of the QSFP port on a 2U server.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/ru2-network-qfsp-server.png)

      The following image shows the location of the QSFP port on the 1U server.  
![\[An image of the QSFP port on a 1U server.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/cubscout-qsfp.png)

   1. Plug in the QSFP with the pull-tab in the correct orientation.

      For the 2U server, plug in the QSFP with the pull-tab on top as the following image shows.  
![\[Shows the QSFP cable plugged into a 2U server with the pull-tab on top.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/qsfp-on-2U.jpg)

      For the 1U server, plug in the QSFP with the pull-tab on the bottom as the following image shows.  
![\[Shows the QSFP cable plugged into a 1U server with the pull-tab on the bottom.\]](http://docs.aws.amazon.com/outposts/latest/install-server/images/qsfp-on-1U.jpg)

   1. Ensure that you feel or hear a click when you plug the cables in. This indicates that you plugged in the cables correctly.

1. Connect breakouts 1 and 2 of the QSFP cable to the upstream networking device.
**Important**  
Both of the following cables are required for an Outposts server to function.  
Use the cable labeled 1 for LNI link traffic.
Use the cable labeled 2 for service link traffic.
