Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Rackmount UPS twistlock question

No, you will need to have a 30 amp twist-lock socket installed.
I suppose if the ups' *actual* power requirements were low enough
you could replace the line cord on the ups, but installing the proper
outlet would be the "right thing" to do. Modifying the ups would
probably void it's warranties and certifications.

Per code, you can't simply change the plug on the end of the cord. It's a bad idea anyway. If the UPS draws more than the new plug can handle it can melt and possibly catch on fire.
The proper way to handle this is to have an electrician install a new 30 amp circuit with the proper breaker and outlet in the server room.
If for some reason the exisitng 20 amp curcuit actually used 10 guage wire it will be a simple breaker and outlet change. But if the wire is 12 guage, which is what is needed for a 20 amp circuit, the wire can't be used.

There are standards, at least you aren't using OLD 20A twistlock (those cought on fire under normal use)
It's just the right ammount of amps for the device isn't the right ammount for everything else. How would you like to plug your cell phone charger into a 30A twistloc?
The great thing about standards is there are so many of them.puck said:
Like tekie was saying, though, the differences in plugs are there for a reason. You don't want to be plugging a device that might draw 30 amps into a 15 amp plug, but those devices are rare enough that you don't want to pay the extra money to make all outlets and wiring handle the 30 amps, thus there has to be a difference purely out of safety. Was that sentence long enough.
