Do not reflash the ROM on the KVM, in any circumstance whatsoever. This sounds a bit silly to put as a general machine room rule of thumb, but it's actually a very bad thing, because you can't use the KVM for a while, and then you have to re-input the server names so that everyone else knows how to get to the machine they're supposed to use. Fortunately, that hasn't happened for a very long time now, but it used to be a common occurrence. (Jeff Arnold, Jeff Grafton, and Dan Tran used to be particularly bad violators of this). It was eventually determined that the key sequence "Scroll-Lock Scroll-Lock r" would initiate the ROM reflash sequence, and Scroll-Lock was often pressed to regain control of the terminal (make it not sleep). Many times after this happened, one would begin typing "root" and badness would result. Try typing something else first to make sure you're not going to do Bad Things®.
