PDP-11/03 basic questions

Today I powered up the "new" 11/03-L, with which I have absolutely no experience. The POWER OK light blinked slowly on and off for a while and then went out. Now it doesn't come on at all. The top card in the cage, though, has a row of red LED's and a large green one, all of which are lit. Power supply is H7861, cage is BA-11SA. The cards from top to bottom are: M8189 2 Mb Clearpoint memory card (don't see a model number) M8061 M7957 M8053 Dilog CQ 1610 card (what is it? Many 2861 PLCC chips in sockets) M8029 I didn't see a lot of 11/03 manuals on the bitsavers site. Before I do a lot of searching and headscratching, can one of the -11 gurus tell me what kind of beast I've got here? Or point me to the appropriate manuals? thanks Charles
