---+ Notes

<ol>

<li>Power to the main server room will be removed by throwing the breakers in the distribution board.  The three for the core switches have been labelled; it'll be interesting to see whether they're correct or not.  Restore power after marriner is back up.

<li>Power to the self-managed server room will be removed by throwing the main switch in the distribution board.  Restore power after everything else.

<li>Power cables in the comms racks to be labelled to make the necessary disconnections/reconnections easier.<br><em>Done - idurkacz</em>

<li>Trailing TP cables to be set up from core0 for CO's laptops.<br><em>In hand: the eight core0 ports C13, C14,&nbsp;..., C20 have been set to DHCP; cables need to be attached - idurkacz</em>

<li>The unused Sanbox 5600-2 is to be liberated from Rack 4.

<li>Techs' help to be arranged for powering off the closets.<br><em>In hand</em>

<li>Turn off Nagios alerts for the entire period by:
  <ol>
    <li>Just before the power-off, hand-editting the file =curlew:/usr/bin/notify-by-jnotify= and replacing the line
<verbatim>
  my $message = join("\n",<STDIN>);
</verbatim>
by
<verbatim>
  my $message = join("\n",<STDIN>);
  exit;
</verbatim>
    <li>On curlew, =om nagios_server stop; om nagios_server start=
  </ol>

Revert all this after the power-off is over.

  </ol>
