MBL connects to router through two chained switches, but not to one

This is driving me nuts. I have a slave 5-port switch connected to my main 16-port switch, and my MyBookLive works fine through that, but if I connect it directly to the main switch, it doesn’t show up in the router IP list nor is it accessible on the network. The Ethernet lights are: one on solid, one blinking only very occasionally, not rapidly like it should. Any suggestions? Tried several cables, different ports, etc.
