We have 2 M4300-52G-PoE+ ProSAFE 48-port 1G PoE+ and 2-port 10GBASE-T and 2-port 10G SFP+ switches, both with a AGM731F SFP Transceiver in port 52 on each. After a power outage, we always have to reseat these transceivers in order to get them back online. Is this normal? Is there a way to prevent this?
Re: AGM731F had to be reseated after a power outage.
Definitively not a normal operation procedure.
What firmware is installed and active on these M4300-52G?
Intentionally deployed 1000BASE-SX SFP? Are these used for the direct connection of these two switches? Or are the other 2-10GBASE-T ports configured into a lag somehow?
Re: AGM731F had to be reseated after a power outage.
The 2 M4300 switches are stacked using ports 51 on both, with the AXC761transceivers and the connector cable.
Ports 52 on both M4300 switches have the AGM731F transceivers and are members of Lag 1, connecting OM3 fiber to our top of rack switches in our server room.
Whenever we loose power for a long enough time that the UPS times out and these switches shutdown, when the power is eventually restored, both AGM731F transceivers are not responsive with no link or activity shown on them. I then have to disconnect each one, pull them out and push them back in, and reconnect the fiber connections to get them to come back up. Would really like to figure out how to prevent this from happening, so that when power is restored, they come back online on their own.

Unless I'm wrong (more of a Smart Switch Series geek), we have no LAG spanning multiple devices on a stack, lack of what is named MLAG. But then, why should the single fiber link to the unknown (1 GB really?) rack top switches. This is why I asked about more details in this area. Should the copper links and the fiber links associated to a single LAG?
Re: AGM731F had to be reseated after a power outage.
The LAG on the stacked switches works fine. The only issue we are having is when we experience an extended power outage that goes beyond our battery backup. After the power is restored, the two AGM731F transceivers will be unresponsive. We have to disconnect them from the switch and reseat/reconnect them again to get them to "wake-up".
We'd like to know if there is a way to prevent having to do this. If there is a setting that can be changed to allow those transceivers to automatically enable themselves after a power outage.

Provide exact insight - what is the LAG config about here, please?
For whatever reason, the ports seem not to come back enabled after a cold boot (power loss), requiring unplug and re-plug the AGM731F modules.
