Number Of People; Tasks And Roles - Sun Microsystems Datacenter Switch 3456 Installation Manual

Number of People

The minimum number of people involved with the installation of the Sun Datacenter
Switch 3456 is two. Many tasks involve two people to maintain safety. While some
tasks only require one person, three people is ideal as it provides redundancy in
some situations and makes many tasks easier. Four people can make a couple of
tasks very easy. Yet in most situations, four or more people are detrimental, as they
might end up interfering with each other's work.
