CTX100 Power Considerations
72 Strata CTX General Description 11/02
CTX100 Power Considerations
The power supply in each CTX100 Base and Expansion Cabinet furnishes power to all of the
stations and some of the interface peripherals (see Table 18). The primary AC power for each
cabinet is 120VAC.
CTX670 Power Considerations
The power supply in each CTX670 Base and Expansion Cabinet furnishes power to all of the
stations and some of the interface peripherals (see Table 19). The primary AC power can be
120VAC, 208VAC or 240VAC. Systems containing six or seven cabinets require 208VAC or
240VAC.
