CTX100 AC Power Considerations
The power supply in each Strata CTX100 Base and Expansion Cabinet furnishes power to all of
the stations and some of the interface peripherals (see Table 2-59). The primary AC power for each
cabinet is 120VAC.
CTX670 AC Power Considerations
The power supply in each Strata CTX670 Base and Expansion Cabinet furnishes power to all of
the stations and some of the interface peripherals (see Table 2-60). The primary AC power can be
120VAC, 208VAC or 240VAC. Systems containing six or seven cabinets require 208VAC or
240VAC.
