CAUTION: GS7xxT v6.3.1.43 update destroys SNMPv3 credentials!

Note that the nodejs net-snmp library does not support any of the SHA2 family algorithms, hence if you're (directly or indirectly) relying on this library you will not be able to securely manage your switch after upgrading to v6.3.1.43. You'd need to use SNMPv2c instead, which has no security whatsoever, or downgrade back to v6.3.1.39.
Another caution: if you downgrade back to v6.3.1.39, the password of the web interface will get reset to factory default ("password").
