Power Considerations
Each CTX670 Base and Expansion Cabinet houses a power supply that furnishes power to all of
the stations and some of the peripherals that interface with the cabinet (see
Table 1-60, “Strata
CTX670 Electrical Characteristics” on page 1-46 ).
Reserve Power
Two or four customer-supplied 12VDC reserve batteries can be connected to the system to
maintain normal operation during a power failure (see
Table 1-63 on page 1-48 and Table 1-60 on
page 1-46 ). The batteries are kept in a highly-charged state by the standard power supply and must
be connected when the system is operating normally. Fully charged batteries must be connected
when normal AC power is available, batteries cannot be connected after/during an actual power
failure.
Underwriters’ Laboratory (UL) and local electrical codes require certain standards for connecting
commercial AC and reserve power to the CTX670 system.
Table 3-1 describes which assemblies
may be required to meet UL and local electrical code standards.
