# Detailed information about the Soyuz descent module connection box?

Anyone have some detailed information about how all this connectors, located in the soyuz descent module?

Are they used only when they setup the Soyuz or they are also connected to the equipment module?

I get this picture from the module TMA-19M exposed in the Science museum in London

Update 2 (MS-04)

From this Soyuz MS-04 Construction, Testing and Integration video we can see this connection box multiple times

• Welcome to Space! Nice question. – DrSheldon Jun 8 '19 at 22:32
• Thanks, i see today one of this modules in the science museum of London and it was very impressive that amount of connectors. – Ricardo Albear Jun 8 '19 at 22:36
• Soyuz: A Universal Spacecraft identifies it as "umbilical connector panel" but doesn't state whether or not it's an interface to the equipment module. – Russell Borogove Jun 9 '19 at 3:22
• A quick browse through the Soyuz Crew Ops Manual yielded nothing either. Is this a standard module? It looks different from the one behind it. – Organic Marble Jun 9 '19 at 11:01
• I found more related information, looks like its connected during the flight so is not only for building or testing purposes – Ricardo Albear Jun 9 '19 at 12:06
