www.mgeups.com Power Protection for Voice over IP, and other new, Mission-critical Network Applications Brad Amano Market Segment Manager MGE UPS SYSTEMS June 20, 2006 Powering the Converged Network Voice Data Power page 2 Market Opportunity Significant VoIP advantages over traditional enterprise telephony networks > Reduced carrier circuit charges > Enhanced applications – Desktop video conferencing – Voice-enabled Web sites > Integrated management systems and strategies > Increased flexibility for a reduction in overall complexity and elimination of circuit redundancy page 3 Market Opportunity Power over Ethernet Standardization > IEEE 802.3af – This standard allows a convenient and cost-effective powering of the phones (no local desk DC power needed) as well as simple, centralized power protection of the whole installation directly from the switch/wiring closet. page 4 IP Telephony Considerations Key considerations in the implementation of Power over Ethernet > Availability – Five nines (99.999%) availability – 5.3 minutes or less of downtime per year > Simplicity of installation – Elimination of individual AC sources page 5 Powering IP Phones Utilizing PoE Switches Patch panels Utilizing PoE Midspans PoE powered IP line (cat 5/5e/6 cable) PoE powered IP line (cat 5 cable) Non powered IP line (cat 5/5e/6 cable) Non powered IP line (cat 5 cable) Patch panels PoE midspan PoE Switches UPS & battery extention (long backup time) Connection to backbone UPS protects the rack equipment Switches Connection to backbone UPS & battery extention (long autonomies) UPS protects the rack equipment AC In AC In page 6 Selecting the Appropriate Sized PoE Midspan and UPS At servers and switches level Active Equipment (Switches, IP PBX) UPS vs. Centralized Active Equipment (Switches, IP PBX) UPS page 7 Selecting the Appropriate Sized PoE Midspan and UPS Example: Switching closet with 96 IP lines (4x 24-ports switches) providing connectivity to 48 users, each with a PC and a PoE-powered IP phone. Equipment 24-port switches without PoE support 24-port switches with PoE support Midspan units Other equipment Rated input Power in Watts 150 400 220 0 X X X X X Number of stacked switches 4 0 2 0 X 1/Power Factor X X X X 1.10 1.10 1.05 1.43 Extra power margin for future expansion Total UPS Sizing page 8 = Power in VA = = = = = 660 0 462 0 40% = 1,570 Selecting the Appropriate Sized PoE Midspan and UPS UPS Technology > Line-interactive > True On-Line, Double Conversion – Ultimate Voltage Regulation – Genset Compatibility Remote Management > Manageability of PoE device and UPS > Reduction of costs page 9 PoE Applications VoIP Initial applications : > IP telephony > Wireless LAN > IP video surveillance Extended applications > > > > RFID tag readers Bluetooth access points Thermostats Security access control (badge readers) > POS terminal devices (scanners, credit card readers) > Alarm systems, smoke detectors > Mini laptops, PDAs WLAN page 10 Conclusion Change in the way we think about powering network components. New network applications and devices are adapting to and greatly benefiting from such technology. With the combination of this standard, it is now convenient, easy to manage and cost-effective to reliably power network devices such as IP phones, wireless access points, IP-based security devices and many other devices. page 11
