Power-Related Hardware 3

Your Lucent Technologies representative can plan for added power-related hardware to provide your system with additional power and protection from power surges, although most systems do not need extra surge protection. Other accessories apply to system-specific conditions.

Power Accessories 3

In a power failure, battery backup units can keep the system running for several hours. When you connect adjuncts and adapters to telephones, the power requirements for the telephones and the system increase. Sometimes it is necessary to add a power accessory, described in this section, to an individual telephone or to the system to accommodate these additional needs.
