failure on 2960s stack iOS upgrade

applied an iOS update to a stack via tftp. I used the archive Download-sw tftp:// method. I rebooted the stack after complete and it never came back up. I discovered the master switch upgraded but not the member. The member was sitting there with all amber lights on and frozen after the iOS load. The master wouldn't finish boot until I removed the member from the stack. I had a version mismatch and they would not communicate.

What did I do wrong in my upgrade process?

Before reload, you had to make sure each stack member had the IOS in their flash with the command;

dir flash1:

If the image was not copied to the stack members, you could've issued the command archive copy-sw

Use a USB stick to upgrade the IOS or you can use the Management Interface.  In order for you to gain access to the member, power down the master and let the member run autonomously.
