Dell 2700W UPS Console Login and HTTPs

Posted by paris on May 30, 2016 in Fixes

 

Default password for console is admin

After setting the IP , you need to reset the management card

Once set , the http webserver listens you go to it and it displays

Unable to display webpage after clicking

The card is configured in SSL mode.
Click here to go in HTTPS.

however https:// does not load.

This is due to the low certificate this device uses for https communication ( 512 ) and RSA keys under 1024 bits have been blocked

You can re-enable this with 

certutil -setreg chain\minRSAPubKeyBitLength 512
