    Why does the backup Coyote Point Systems Stereo Equalizer continue to boot?

      Samuel SawyerAug 14, 2025
      If the backup Coyote Point Systems Stereo Equalizer continues to boot, it might be due to a conflict with the primary Equalizer. This can happen if certain Dell and Cisco switches have Spanning Tree enabled by default, causing a delay in network accessibility and triggering failover mode. To resolve this, either disable Spanning Tree or enable PortFast for all ports connected to the Equalizers.

      If clients are timing out when trying to contact a virtual cluster on your Coyote Point Systems Stereo Equalizer, several factors could be at play. It might be that the Equalizer isn't properly gatewaying reply packets from the server. To resolve this, log on to the server(s) and check the routing tables and perform a traceroute from the server to the client, adjusting the routing until the Equalizer's address shows up in the traceroute output. Another potential cause is having the test client on the same network as the servers. In this case, the servers might try to send data packets directly to the client, bypassing the Equalizer. To fix this, add host routes on the servers so that they send their reply packets via the Equalizer. Also, ensure there are active servers in the virtual clu...
