AP1852E Cisco Mobility Express Controller Issues

[bluecorvette86]

I have an AP1852E that I have started setting up.  It is connected to a local trunk port on my switch, with the management VLAN configured as the native VLAN.  When it first started up, the Cisco Mobility Express Provisioning ran just fine, I entered all of the revelvant information, and completed the setup.  Upon reboot, the controller never successfully boots back up.  I just keep seeing the following message form the console:

"waiting for uplink IP address and reachable default gateway"

I can see that the AP is pulling a DHCP address just fine, just like it did upon first setup.  I have tested this using an access port on the management VLAN and the controller will start up just fine, but that does me little good.  Any ideas what I need to do to get teh controller to boot up properly while connected to a trunk port?  Thanks!

When you boot up a Mobility Express AP, it takes around 5-8 minutes before it boots up to a controller.

Scott,

Thanks for the reply.  It has been sitting here for a couple hours with no change.

I had similar issue, do i need to console in to make changes to the DHCP. How do i get back into the box or UI to make changes?

[Scott Fella]

You need to console into the AP to see if the unit has obtained a DHCP address. You could always factory default the AP if you want to be able to UI using the day 0 setup.

Hi everyone,

Does someone knows if the AP 1852I works as standalone without connecting to wired network? I´m going to setup a Site Survey and I need to use the 1852I as Autonomous AP but I didn´t find in the Cisco Software Center any version to be used as autonomous only LWAP and Mobility Express.

Thanks for your comments.

Neyton

[aesmaeil]

There is no Autonomous Code for 1852I.Your only option is to use Mobility express.

Ali,

Hi Scott,

Could you help me with the similar problem.

I just bought a AIR-AP1832I-H-K9. 

It is a thin AP by default.

I try to change it to MOBILITY EXPRESS how ever, I can't due to some reason.

I plugged in the console and use PuTTY to check and found a message keep showing on the screen.

"waiting for uplink IP address and reachable default gateway"

The following is the output of my console and show version.

[kphang]

I reolved my issue once i managed to console into the ME AP. The issue was i have plugged into a lightweight environment and had changed it into lightweight AP. It went into the CAPWAP discovery process. Once i updated the firmware back to ME, it all works and start broadcasting CiscoAirProvision SSID.

I still have another unit that won't boot up when i plug into the same PoE switch, but when i plug into AC power adapter it works. Could be hardware issue.

[Scott Fella]

You shouldn't bring up a ME AP when there is a WLC or IOS-XE MC on the network. Any mobility express AP should be on a network where there is no controller and or remove any option 43, DNS or layer 2 broadcast capabilities.

-Scott

[kphang]

Agree. I plugged it in because i was testing the power issue on the first one that i mentioned. Conveniently i took the second unit and test out the PoE. After that i try to bring up the second unit as ME, and that is where i faced the bootup issue. Anyway, thanks Scott and everyone. I am happy with the performance so far.

[Scott Fella]

Glad to help.
