Ok, the rodent issue is dealt with. Everything has been taken apart (and documented), cleaned thoroughly, and put back together. Now I'm completely lost. Plugging it in, the large orange light on the PSU lights up. With the switch on the PSU switched to "LOCAL" and the breaker turned on, the blower kicks in. Thing is, I don't have a key for the front panel power switch. However, James Lothian's 11/750 FAQ says that the power supply being switched to "LOCAL" should override the key setting and power up the machine, but the power light on the front doesn't light up, nor does anything else. On the PSU, there are no failure lights, but "Power OK" doesn't light up either. Any thoughts? John
