Pitfall 2: "Switch boots into ROMmon after upgrade"
Cause: The boot variable still points to the old file, or the new image is corrupted.
Solution: At switch: prompt, run set BOOT=flash:c3560e-universalk9-mz.152-4.e10.bin then boot. C3560e-universalk9-mz.152-4.e10.bin -UPD-
Pitfall 3: "The -UPD- file causes high CPU for process 'Spanning Tree'"
