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, ..., 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> </ol> -- Main.TobyBlake - 15 Dec 2009 -- Main.GeorgeRoss - 15 Dec 2009
