bottom one >:)...... just got it. found it on ebay for 30$. they said wasnt tested, and it wouldnt turn on. i took the risk. bought new batteries and it works perfectly!!! a smart ups1400 new is prob like 800$. i tested it and it ran for 35mins and still had 2 bars left with a battery that wasnt fully charged. so now the site should have have less downtime
first one powers modem and switch and the bottom one covers the server.
