I have an APC Rack PDU AP7920 (hardware revision B2, manufactured 07/21/2012). When I log in via telnet I get:
American Power Conversion Network Management Card AOS v3.3.4 (c) Copyright 2005 All Rights Reserved Rack PDU APP v3.3.3
I would like to upgrade the firmware. On the APC website, I found two options (they are very hidden for some reason):
apc_hw02_aos392_rpdu392.exe (i.e., v3.9.0/3.7.4 and 3.9.2/3.9.2).
go.bat and entering correct IP address, username and password, I get for both:
Checking network connection ... ERROR!!! Login unsuccessful.
That's definitely not true: IP and login details are 100% correct. How can I upgrade this?
