LifeSize support said we should write a python mechanize script to shutdown the server via script.. this is an implementation of that! https://community.lifesize.com/thread/2249

remote_shutdown_lifesize.py

import mechanize
import cookielib
import urllib2

# Configure the server IP, Username & Password (defaults provided)
server='10.0.0.1:8181'
username='administrator'
password='admin123'

# Using mechanize: http://wwwsearch.sourceforge.net/mechanize/
br = mechanize.Browser()
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)
br.set_handle_equiv(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]
# You may need a proxy server
#br.set_proxies({"http":"proxy_server_ip:3128"})
try:
	url = 'https://%s/server-admin/operations/shutdown/poweroff' % server
	print "Shutting down server: %s" % server
	br.open(url)
except urllib2.URLError as e:
	print "Failed to connect to %s" % server
	exit
# Login using the web-form
br.select_form(nr=0)
br.form['username']=username
br.form['password']=password
br.submit()
# Push the "shutdown" button on the confirmation page.
br.select_form(nr=0)
br.submit(name='power-off')
print "LifeSize server is shutting down."
# Output whatever the page says, should be: "Powering off the server."
print br.response().read()
