Cannot connect to ProCurve Switch 2650 after software upgrade

I have update ProCurve Switch 2650 from version 10.50 to 10.70. When I reboot switch it became available for ping and telnet some time and then (about 1 day) became unreachable by ping and telnet. But it still working (ports are active, computers are working in network), but I cannot to connect to switch by telnet or ping it. Howerer arp work and I see MAC of switch (arp -a). And I still can connect by console port.

Hello,
the actual firmwareversion for a 2650 is H.10.74.
Update to this one and try again.

In my first message I wrote a mistake. In really firmwareversion is 10.74 (not 10.70). And I tried to load it (10.74) several times, but problem is persist. We have 30 switchs ProCurve Switch 2650 (2626) and after update 10 of then have one problem (became unreachable by ping and telnet).

There is nothing interesting or something that can help to understand reason of problem. If you wish, I can attach "show tech all" information from one of problem switchs.

Can you list a sh run from the Switch?

Maby there are config settings like STP or other.

In what case STP settings may call problem with IP ?

When STP is enabled and the topology changed it is possible that the switch is unreachable.
You can look in: sh spa det
Here you see the counter for changing and the last change.

At least try to downgrade and look if same faultys happens.
