In my previous post  I was talking about how to fix the corrupted IOS in Cisco 1250 Series Wireless Access Point. Now in this series let’s see how to fix the solution to fix the corrupted IOS in Cisco 1250 Series Wireless Access Point.

 

In the previous post we know that whenever an IOS is missing in the Cisco Wireless Access Point you will get the following error

 

The system is unable to boot automatically because there are no bootable files.

 

Followed by the promt

ap:

There are two ways to fix this problem, in this post I will show you how to fix the problem   by transferring the IOS file to the Cisco Access Point using a TFTP server.

 

 

Whenever you boot you IOS corrupted Cisco Access Point and when you get following error at the command prompt

 

ap:

 

Connect the corrupted access point to any Cisco Catalyst Switch and also connect your PC with a solar winds TFTP server installed to the same switch with the same subnet. In the following example we are configuring the IP address for the PC with Solar winds TFTP server and corrupted access point as follows

 

 

Follow the below mentioned steps

 

Step 1:

Assign the ip address, netmask and default gateway to the IOS corrupted access point by using set command as shown below.

 

ap:set IP_ADDR 10.0.0.10

 

ap:set NETMASK 255.255.248.0

 

ap:set DEFAULT_ROUTER 10.0.0.10

 

Step 2:

Initialized the TFTP server in the Cisco Access point by entering “tftp_init” command

 

ap: tftp_init

 

 Step 3:

Download the IOS image file for Cisco 1250 Series Access Point from Cisco Web Site (CCO id is required) and remove the file extension (.tar) as shown and copy the file to solar winds TFTP server directory.

 

Step 4:

Make sure that the solar winds TFTF server is started and the downloaded the IOS image file is placed in the TFTP server directory.

 

Step 5:

Extract the IOS file downloaded into the Cisco Access Point by using “tar -xtract” command to inflate the image file from your TFTP Server.

 

ap:  tar –xtract  tftp://10.0.0.8/c1250-k9w7-tar.124-10b.JDA3 flash:

 

 

 

Step 6:

Once the whole IOS file is extracted the set the boot path in your IOS corrupted Cisco Access Point as shown below

ap:  set BOOT flash: c1250-k9w7-mx.124-10b.JDA3/ c1250-k9w7-mx.124-10b.JDA3

 

Step 7:

Then you boot your Cisco Wireless Access Point by using a “boot’ command.

 

ap:  boot

 

 

Once the Cisco Wireless Access Point is booted you will see no errors and its working fine. I have also uploaded the video as well which might help you to recover the IOS in a Cisco 1250 Access Point. Same procedure can be applied on other Cisco Access Points as well with proper IOS files.
