TECHNOLOGY

Power over Ethernet Controllers (PoE)

•Network is installed by the Computing Services group

•Controller receives power from the Ethernet cable

•Installed and operated by Computing Services

•Computing Services provides the PoE switches

Lessons Learned

l ll f d•Earlier installation of IT equipment required

•IT installation moves to the critical path for the     substantial completion of the building

•Need a strong team effort between the Computing Services group and the Controls contractor
