As there is 2 interface in MR57,ports can be used for 10Gbps agg. throughput and POE power.... Customers want to connect both ports from different switches for HA requirement, Can we use these interface for HA purpose.  If it is possible what configuration we should do.

If you have a switchstack you can use lacp

In case of no stack/lacp port2 gets disabled. im not certain if port2 gets enabled when it detect a problem on port1.  (But i think not because of its called disabled and not something like standy/backup)

Note: High Availability and Power Sharing will be available in future firmware versions

We recently did an install using 5 GB Cisco 9300 switches, and had to port channel on the same switch.  We are using shared power on the stack for resiliency.
