ICX 7150-C12P factory reset not initiating?

Disclaimer: I am not tech savvy so I apologize if I don't use the right terms.

I moved into my first home and found the cable box a complete disaster. I eventually found the Ruckus switch and 2 access points mounted on the ceilings. However, it seems that none of the ports on the back are configured for POE, so I attempted to use the switches IP to login and troubleshoot the issue. It appears one of the previous owners may have changed the password, because none of the default usernames and passwords I've found have worked. 

I attempted a factory reset of the switch, but it doesn't seem to initiate. I've done the following steps:

Unplug power, press factory reset button for 10-15 seconds, turn power on while continuing to hold factory reset button (I've tried holding it for anywhere from 5-60 seconds).

The only thing that happens as soon as I turn the device on (while holding factory reset button) is that the status lights briefly flash amber once, the system light turns yellow, the power light turns green. Eventually the system light turns green.

Am I doing something wrong?
