stack grayed out in inventory manager using firmware manangement

[JohanHendrikx]

I want to do a firmware upgrade using inventory management. The stack is gray out. An other stack I can do an upgrade. Both stacks are simular (same modules and same firmware.)

Why is the stack gray out ?

This is probably an SNMP Polling thing.
See "Netsight: All devices grayed out in the firmware upgrade wizard" in GTAC Knowledge.

I believe a key point of that article is that SNMP Polling is device-specific - so that it could be enabled on one device and disabled on a different (and grayed out) device.

Paul, not all my devices are grayed out.

Sometimes it helps to rediscover the switch = netsight console -> choose the device -> rightclick -> refresh (rediscover) From my understanding the swith was not reachable during the discovery and the device type is not fully propagated through the Netsight. Good luck
