we bought cisco aironet 1600 series AP. we can logon using console but we cnt get into the global configuration mode. i dont have a power cable and since it only has one ethernet port um unable to confogure it using a web interface. and the swith that i am connecting it to does not support POE. what can i do?
Well after going to your query I must suggest you that you refresh/upgrade you Firmware.
Besure that if you are using LAP then firmware is accordingly and if its Autonomous AP then firmware is different. You can get it from Cisco website.
Furhter more normal scenario is that for LAP you can but you dont need console access as it works with WLC and you can manage it from WLC.
FOr Autonomous you can config via console or GUI.
Now for your question as you mentioned you dont have power cabel if you dont have power cabel then you need PoE if your switch dont support PoE then I think you need other switch who support OR use power cabel, because for console access you need power what ever the AP is LAP or autonomous.
So bottom line is that you give power to the AP via power cabel or Ethernet and access it via console if its not LAP or you need CLI access only to do things manually. then from there you can go into global config mode as the fireware is upgraded previously so you dont have any issue.
