Transcript of "Richard Jansen, CIO at UKZN - POE and the changing face of the CIO portfolio"

  1. 1. Richard JansenCIO – University of KwazuluNatal
  2. 2. Power over Ethernet (PoE) and its impact on the CIO portfolioPoE is the transfer of electrical power, along withdata, to remote devices over standard data cablesin an Ethernet network (Cat3/Cat5/Cat5e/Cat6 ).
  3. 3. IEEE802.3af-2003 Specifications• The original IEEE 802.3af-2003 standard version of PoE supplies up to 15.4 W of DC power (minimum 44 VDC and 350 mA) to each device.• Only 12.95 W is assured to be available at the powered device (PD) as some power is dissipated in the cable.
  4. 4. IEEE802.3at-2009 Specifications• Cabling: CAT5E required• Power Feeding: 2-pairs and 4-pairs possible – Focus on 2-pairs Medium Power: PSE 30W output, PD 25.5W input – 4-pairs High Power should be based on 2x2-pairs: PSE 60W output, PD 51W input• IEEE 802.3az Energy-Efficient Ethernet – savings upwards of 3 watts per link
  5. 5. Integration• Open standards• Management platform

  7. 7. King III Governance• Chapter 5 of King III requires IT representation on the board• Why are we only paying lip service to this requirement?
