I have 3 APC PDUs for sale (pics below). They are 1U rackmount, 15amp units with 8 ports each. Frankly, I don't know the model number. I believe they are part of the discontinued MasterSwitch line. They allow for remote power cycling and some other features that we never used
They still work great, and they were pulled from a working environment. We simply upgraded our entire network and these are no longer needed.
Asking $30/ea or $75 for all 3, plus shipping. Paid via PayPal. Will give preference to shipping within North America, but will accept offers from anyone.
You can create different user accounts that have access to a specific port - thus allowing you to provide a client with the ability to reboot ONLY their server(s). Otherwise, yes, you can simply do it for your customers through the master login.
