Problem: Quality and reliability of service are primary concerns of any IT specialist, and for good reason. When purchasing and installing a VoIP phone system, high standards of quality and reliability are expected, but not always achieved. Without additional AC outlets for each phone, coupled with the possibility of an occasional power outage, how can reliability be achieved?
Solution: Using a PoE (Power over Ethernet) switch could increase the quality of a VoIP hosted PBX system and could therefore positively affect the quality of service. PoE technology can save time and cost of installing separate power cabling and AC outlets and eliminates the need for a dedicated uninterrupted Power Supply (UPS) for individual devices connected to the Ethernet. This means that in it is possible to centrally back-up IP telephony phones in the event of a power failure.
In the design and installation phase, power supply is often overlooked or underestimated, which could lead to increased cost and loss of time. PoE reduces the need for dedicated power protection at the desktop but can increase power protection requirements at the switch level.
Not all companies that provide hosted services include PoE due to the extra cost, but as the customer, it is important that you are aware it is an option.
Problem: While the use of a Power over Ethernet (PoE) switch eliminates the need for a dedicated Uninterrupted Power Supply (UPS) for individual devices connected to the internet, system reliability could still be at stake in the event of power failure.
Solution: A power backup to your data room, specifically the PoE switch is crucial to maintain uninterrupted service.
A UPS provides emergency power to a system when the input power source fails. It is different from an emergency power system or generator in that a UPS provides near-instantaneous protection from power interruptions.
The use of a PoE increases reliability and flexibility of a phone system by removing a point of failure in the external power supply. PoE simplifies installation because only one cable is needed, so the workspace is uncluttered.
Using a backup batter system like a UPS on the PoE switch ensures that all of the IP phones in your system will maintain power in the event of a power failure.
