MCS-7825 won't copy OS 2000.4.3(a) image

See bug at:

Apparently, Cisco doesn't know why it happens to some and not to others and there is no way to prevent running into it. When attempting to load OS 2000.4.3(a) on a supported MCS-7825-H2 or the like, everything will proceed until the image is copied o the disk(s). The copy will fail and you'll have to begin the process again.

You can simply keep retrying (it may take a dozen attempts) and ultimately it will work, or follow the steps on the link re: trashing the RAID array. If that doesn't work:

"If perform all of the above steps and this has not resolved the issue, I have also seen it resolved by performing a System Erase from the HP SmartStart CD menu options (when booted from), prior to installing. If you do not have a SmartStart CD, you may be able to perform a similar action in the BIOS menu (F9 on boot-up) to Erase NVRAM/Boot Disk in the Advanced Options sub-menu. "

Cisco 1841 and HWIC-AP-G-A

Although the website indicates all K9 IOS versions support the HWIC-AP-G-A, you must still use the T-train versions. Last success was using c1841-adventerprisek9-mz.124-2.T2.bin, verses new and improved but not supportive version c1841-advipservicesk9-mz.124-12.bin.

During boot you'll see UNKNOWN CARD in slot X if not supported.

Cisco LWAP 1131 and 4404 WLAN Controller

If you follow the quick setup guide for the 4404, you are really basically on target. Enter some IP addresses for your interfaces, DHCP server, Radius, etc., verify you have the appropriate layer 2 or 3 connectivity to your APs, plug them in and you've got yourself a nice wireless network.

  1. If you are using 1131 APs, you'll likely need to upgrade the 4404 code.
  2. Set the time on the 4404 correctly!!!!

I've heard the time is important in training, saw documentation about it, and of course forget to check it everytime.

My experience is that you can stare at your configs all day and while nothing appears out of line, your APs won't find an AP-Manager and will happily keep rebooting forever.
