Key ChallengesDesktopPhone availability is affected by power problems if the phone is powered locally.IDFHeat dissipation, physical space, high availability, and electrical wiring need to be quicklyupgraded. Switches power the phones (15W per phone)Loads increase from 1000W max to 4000WSwitches and UPS(s) require much more spaceNetwork must provide same availability levels as legacy telephonyMDFPhysical infrastructure (rack, power, and cooling) needs a quick upgrade. UPS loads are much larger than the existing UPS can handle. The current UPS/Cooling solutions are not designed to provide the new availability requirements. Entire infrastructure may need to be replaced due to space problemsData CenterRacks must be quickly integrated into the data center infrastructure for new switches andservers.VoIP and IP Telephony 2004 APC Corporation.

APC SolutionsVoIP and IP Telephony 2004 APC Corporation.

Key Considerations for SolutionsPower Size the total UPS load not just the switch and beware of how the phones are powered Provide ample run time across the network- 1 to 2 hours is a typical requirement for phones Determine needed availability requirements (N 1 Redundant, 2N redundant, etc.)Racks Select open racks for switches with side-to-side air flow Choose racks that will support the larger UPS and battery frames Ensure availability of enough receptacles and that PDU strips won’t be overloadedCooling Ensure solution allows monitoring of temperature in the room Identify increased ventilation/cooling needs and supplement as neededManagement Design a complete management strategy for entire infrastructure rather than individual equipment Ensure a sound strategy for networks with many remote sitesServices Consider on-site service for locations with little or no support staff; Needs Assessment surveys and ExpertInstallationVoIP and IP Telephony 2004 APC Corporation.
