Hi,

Management port can be used for following features:

  • Management through SSH / WebUI
  • Out of band access to management with AOM
  • Logs / SNMP outbound connections if destinations are in same network as Management port or a specific management route was configured
  • failover heartbeat

The most critical service is failover heartbeat. The recommended configuration is to define 2 failover networks :

  • one HA network
  • Management Network

If your deployment is configured with both networks (

Device Management  ››  Devices  ››  your device ›› Failover
) and HA plan self IPs are defined with Port Lockdown 
Allow Default
or 
Allow All
, you can unplug the management port without issue.
