Appendix – AHX Monitoring

AHX monitoring enables monitoring HDR director switch cooling devices (i.e. AHX) and sending events to the UFM. The events are triggered on the switch associated with the cooling device if the monitoring utility encounters an issue.

The monitoring utility runs periodically and communicates with the AHX devices over the Modbus protocol (TCP port 502).

  1. Enable AHX monitoring. Run:

    Copy
    Copied!
                

    ufmapl [ mgmt-ha-active ] (config) # ib managed-switch ahx-monitor enable

  2. Set the AHX monitoring interval. Run:

    Copy
    Copied!
                

    ufmapl [ mgmt-ha-active ] (config) # ib managed-switch ahx-monitor interval

  3. Add AHX devices for monitoring. Run:

    Copy
    Copied!
                

    ufmapl [ mgmt-ha-active ] (config) # ib managed-switch ahx-monitor device

  4. [Optional] Review the settings. Run:

    Copy
    Copied!
                

    ufmapl [ mgmt-ha-active ] (config) # show ib managed-switch ahx-monitor AHX Monitoring: Enabled : Yes Interval: 1m     AHX Devices: Switch name : switch-01 Primary IP address : 10.10.1.11 Secondary IP address: 10.11.1.11
