Why -48VDC (The Sign)?– The Battery Positive is Grounded– Negative Polarity Reduces Corrosion Problems
with Underground Cables and Conduits
Why -48VDC (The Value)?– Low Voltage (<72V or 60V) Did Not Require
Licensed Electricians– Was Not Governed by the NEC
Why not use commercial AC directly?– DC Was Used to “Carry” Voice Signals– AC Power Was Not Deemed Reliable
Enough for Critical Telecom Applications– AC Cannot be Easily Stored
Convergence Has Blurred the Difference Between Telecom and IT Loads

AC UPS– Higher Voltage Batteries (120 to 240 Cells)– Regulated AC Output Voltage
• Lower End of Discharge Voltage (1.65V/C Typ.)• Longer Runs of Higher Power Feasible
– Power Capacities Available up to 3000 kVA– Redundant Generators Are Typical– 15 Minute Batteries Typical– More Complex

Converged Networks – The Power ChallengeConverged Networks Converged Networks –– The Power ChallengeThe Power ChallengeEntire Network is Critical
Even short interruption can be damagingSingle point of failure for both Data and VoiceVoice prioritization (911 access, QoS)
Traditional Telecom Service Providers Designed System for High Availability Power to the Telephone
Now power to operate network resides in the facilityPower Demand
PoE introduces -48VDC power into Enterprise NetworkPoE consumption can be up 7 times the power for data only
Switch requires multiple, higher ampacity, 208V, or 3-phase powerAdditional power requirements will drive need for coolingVoIP may require longer battery run timesSpace requirements
Changing Responsibility in Enterprise NetworkChanging Responsibility in Enterprise NetworkChanging Responsibility in Enterprise NetworkTraditional Approach:
Two Separate Networks’ Responsibilities
Voice - Telecom Service ProviderData – Data Processing / IT ManagerInfrastructure – Facility Manager
Converged Network:Single network responsibilityIT Manager
May not have Facility Manager(especially in smaller businesses)
Power to Operate Network is the User’s Responsibility
Wall power–Needs DC converter for connectingIP phone to AC wall outlet
Power over the Ethernet (PoE):–External power (Mid Span)
•Needs external power patch panel•Patch panel delivers -48VDC over pairs 3 and 4
–Inline power•Powered linecards for switches androuters•Uses pairs 1 and 2 (same as Ethernet) for delivering -48VDC

What is “High Availability” ?What is What is ““High AvailabilityHigh Availability”” ??Term widely used in the information technology industry– Increasing need for non-stop computing
– Demand for “uninterruptible” power (7xForever)
Not a standardized “product” or “offering”– Manufacturers are free to use the term at their
discretion
– High Availability is more than just a product or
system configuration
Decision maker must determine the level of availability desired vs. cost to achieve
