I recently purchased an Aironet 1142 (AIR-LAP1142N-A-K9) from a government office supply auction. I brought it home and connected the power supply (EADP-18MB) directly to it to make sure it powered up properly. Everything seemed to work properly (the led went through several different color changes), but I didn't have my console cable with me, so I couldn't configure it.
I left the unit powered on and drove to my office to grab my console cable. Upon my return, about 45 mins later, I realized that the unit was powered off and would not come back on. After some research, I noticed that the power supply was not for this unit, even though the input/output specs are correct and meet the Aironet's requirements. Hoping the power supply was the culprit; I ordered a Power Injector (AIR-PWRINJ3) and a power supply (PSA18U-480C). They arrived today, but I'm still not getting power to the unit. The led is not lit, neither is the 'device status' light on the power injector. I tried cycling the unit on while holding the mode button, but I'm still getting nothing.
I was thinking that the led maybe disabled or something, but I cannot telnet to the device or get to the 'ap' prompt in putty.
Could anyone please shed some light to the issue I'm having? Did I fry something out leaving it directly connected with possibly the wrong power supply?
Well, this happened a few weeks ago, so any odor is long gone. I will say that I didn't smell anything strange when it happened. I've just been waiting for the injector and correct power supply to arrive.
I didn't want to crack it open until I received some advice or direction. I'll open her up tomorrow and see if anything looks strange/burnt/melted.
