I followed the Cisco guide for upgrading my WLC to 6.0 code. It tells me to download and install the SWLC3750K9-5-2-157-0-ER.aes file to install the bootloader. I noticed this file was not listed under the 6.0 version, but was found under the 5.2 folder in downloads. Anyways, all went well with the upgrade, and now I can see "Emergency Image Version - 126.96.36.199" listed on the summary page f my controller. My questions:
1. My other controller also has 6.0 software installed, but it's Emergency Image Version shows "N/A". I think that tells me that whoever upgraded to 6.0 didn't also install the BOOT file? Is this a problem?
2. What is the purpose of this file?
