Connecting the Harmonic MediaGrid 3000 System Components
About BMC Connectivity
Each controller on the ContentServer contains a troubleshooting utility called the Baseboard
Management Console (BMC), which can be accessed in the event of system failure. The BMC
requires a 1 GbE connection from NIC 0 on each controller on a ContentServer to the network
switch.
Connecting the ContentDirectors to a Network Switch
Follow these instructions for single-site Harmonic MediaGrid systems. If you are configuring a
stretch cluster, follow instructions in
