According to what I read here
it states "When the BayStack 252 hub is in a managed hub stack, it is referred to as a "slave" because it is managed through a connection to a Baystack 250 or 253 hub. The BayStack 252 hub can also function as an unmanaged hub in a network." To me that implies that it will not work as a managed hub alone.
Another issue is that it is a hub, not a switch. I would not want a hub on a modern network as it would limit throughput and performance for any connected devices. The cheapest switch
would outperform it, and in addition would save a lot on power consumption. Scott.
