+Each node in Sandbox 2 (SB2) has a USRP X310 (with 2 UBX-160 daughtercards) directly connected to it via a 10G ethernet link. This link shows up as {{{eth2}}} on the nodes.
+
+Sandbox 2 also has a pair of 60 GHz 16+16 IEEE802.11ad beamforming transceivers available for optional connection to the X310 frontends.
+
 ===== RF Connections =====
- The X310's connected to the nodes in this sandbox are interconnected via coax cables as follows with a 30dB attenuator on the TX/RX side of each link for protection. This setup is designed to facilitate FDD dependent experiments.
+ The RF connections of the X310's in this sandbox can be configured in one of two topologies.

+ The first topology has both X310's interconnected via coax cables as follows with 30dB of attenuation between each TX/RX & RX2 link for protection. This setup is designed to facilitate FDD dependent experiments.

+ The second topology is for use of the 60 GHz transceivers. In the currently available configuration, the X310 of node1-1 can acts as a transmit-only radio, while the X310 of node1-2 acts as a receive-only radio.

+===== Selecting RF topology configuration =====
+ Use the instrumentation service to check the current configuration as well as make changes to it.
