I have Cisco 2504 Wlan Controller and 12 APs. Yesterday I tried to update system starting by uploading new FUS.
I didn't do any preloading stuff since our WLAN is only use in working hours. Now it has not been accessible for almost 20 hours and other VLAN doesn't show up at all. Controller ports 1 and 2 seems to doing some networking, but ALM LED is amber which states Controller status activity, such as firmware upgrade and SYS LED is also amber which means System failed the bootup process or an error caused the system to halt. A status or error message is posted on the console screen.
I cannot access via SSH or via HTTPS
