Both BRS are still in the middle of an upgrade, we are waiting for some thermocouples to arrive on Friday. As it stands, both BRS look like they are running, but when I logged onto the beckhoffs, one seemed frozen and one was running old code, so I don't believe either is actually in a good state.
For now, we should avoid using either one, so SEI_CONF should stay in TEST_SWARM when appropriate, or SC_OFF_NOBRSXY if there is work in the LVEA or a large earthquake. LARGE_EQ should also be safe.
