This page documents the computers and networking equipment directly related to the radome. General documentation of W1XM's networking stuff (to the extent that it exists) is located in Athena.
This wiki is currently public, do not put credentials or other sensitive data here.
This server is a Factor 202 (industrialized Raspberry Pi) located in the climate-controlled rack on the roof directly under the radome.
It does the actual CANbus communication (see Overview) with the radome motor drives and serves a custom WebSocket-based protocol for controlling the dish remotely.
The WebSocket server and its protocol are in this Github.
This server is only accessible from within RSnet.
This server is a Dell Precision Rack 7910 located in a rack in 54-1912.
It is used to run computations and recordings of data from the software-defined radio(s) for the radome. It is owned by the MIT UHF Repeater Association W1XM.
This server is accessible from RSnet, MITnet, and the public Internet.
This server is a Gigabyte R183-Z93-AAV1-000 located in a rack in 54-1912.
It is also used to run computations and recordings of data from the software-defined radio(s) for the radome. It is owned by MIT Junior Lab (Physics Dept.) and is used by their students remotely.
It has 18 TB of fast storage for SDR data recordings mounted under /data.
This server is accessible from RSnet, MITnet, and the public Internet.
This desktop computer is a Dell Optiplex 7910 located in 54-2101. It is used for casual (non-compute-heavy) access to the radome SDR data and general desktop use in the shack.
It has a fiber link to the radome rack.
This computer is only accessible from within RSnet.
The high-speed fiber networking for the SDR data is separate from RSnet and MITnet, although the switches are connected to RSnet for management.
There are fiber links from the radome's climate-controlled rack to both 54-1912 and 54-2101. The fiber links use the following switches:
1) m54-radome-sw1.mitrs.org – located in radome rack
2) m54-2101-sw2.mitrs.org – located in 54-2101 rack
Currently, one fiber connects the radome switch to the 54-2101 switch. Multiple fibers connect from the 54-2101 switch to w1xm-eme-1, scotty, and laforge.
