Can't change IP address on N5765A

I'm trying to change the IP address on my N5765A power supply using Firefox and I can't get it to change from it's default of 169.254.198.224.  It is an older unit, serial number US13K1169M with firmware revision A.05.06.

Interestingly, when I go to the View & Modify Configuration page and click on Modify Configuration, the Current Setting IP address is 169.254.57.0.

I click on Manual and change the IP Address to 192.168.1.60 and then click 'Save', and then 'Reboot Instrument' but the address stays at 169.254.198.224.

I have tried with Firefox on both Windows and Linux machines with the same results.

What am I doing wrong?

Below are screen shots of the above steps.

Thanks,

Reboot Instrument and nothing changes:
