Page 5-31 of that manual details the LED display codes.

Note also that the Series 37 requires certain PCAs to be in certain slots 
(pages 3-2 and 3-4), so it would be good to verify this too.

And as Gavin mentions, the CPU tries to talk to the terminal after 
completing the self-test, so it's important to have a working terminal 
connected and turned on when powering up the system.
