Is their any methods/utility of updating firmware in the ConneXium managed switches and Firewalls without having to connect via it's embedded web page?
These ConneXium device have 3 user interfaces, which you can access via different interfaces for software upgrade:
1) System monitor via the V.24 interface (out-of-band)
2) Command Line Interface (CLI) via the V.24 connection (out-of-band) and Telnet (in-band)
3) Web-based interface via Ethernet (in-band).
