Another way to shut off the heartbeat is to plug in an Ethernet 'loopback'
connector into the network port. Then tell the DELNI that it is attached
to a network. No heartbeat from the network - no heartbeat on the DELNI.

The connector should have been a part of your DELNI package. We found out
about this at Notre Dame when we started to plug DEMPRs into standalone
DELNIs. Performance was terrible. Connecting the loopback connector and
switching the DELNI to network connected mode solved the problem.
