Add "Can I Power Cycle my nodes?" section to the FAQ, which points off

at the tutorial section describing the node_reboot command.

<h3>Can I reboot (power cycle) my nodes?</h3>
<p>
Yes. Each of the PCs is independently power controlled. If your
node becomes wedged, or otherwise unresponsive, you can use the
<tt>node_reboot</tt> command, as discussed in the
<a href="tutorial/tutorial.php3#Wedged">Emulab Tutorial.</a>
</p>
<p>
The Sharks are also power controlled, but because of the limited
number of power ports available, the entire shelf of 8 sharks is
on a single controller. The <tt>node_reboot</tt> does its best to
cleanly reboot individual sharks, but if a single shark is
unresponsive, the entire shelf will be power cycled.
