Redundant server heartbeat cable
Take care to use the proper serial cable to interconnect redundant K2 Media Servers
that take the role of file system/database servers. This cable supports the heartbeat
mechanism whereby the servers monitor each other’s health. It is a 9 pin serial cable,
but it is not a standard RS-232 null modem cable. The heartbeat cable is supplied with
your system (Grass Valley part number 174-8137-00) and has a pin configuration as
follows:
1 – 4
2 – 3
3 – 2
4 – 1&6
5 – 5
6 – 4
7 – 8
8 – 7
9 – No Connect
