Catalyst 2350 Switch Power-Supply Modules
The switches have one internal 265-W power-supply module ( Table 1-5 ). The 265-W AC-power-supply
module is an autoranging unit that supports input voltages between 100 and 240 VAC. The
DC-power-supply module has dual input feeds (A and B) and supports input voltages between 36 and 72
VDC.
The AC-power-supply module uses an 18-AWG power cord for connection to an AC power outlet. The
DC-power-supply module requires wiring to a DC-power source.
The power-supply modules have two status LEDs.
For more information about replacing a power-supply module, wiring a DC-power-supply module, and
for module specifications, see
Chapter 3, “Power Supply and Fan Module Installation,” and Appendix A,
“Technical Specifications.”
Fan Modules
The switch models has an internal hot-swappable 12-V fan module that inserts in the switch rear panel.
The air circulation system consists of the fan module and the power supply modules. The airflow patterns
vary depending on the power supply configuration.
