Power Supply Module Features
Power Supply Module Features
The Cisco ME 3800X and ME 3600X switches support two power supply modules, either AC or DC
input. You can install two AC or DC input power supply modules, a mix of AC and DC input power
supply modules, or one power supply and one fan module. The power supply and fan modules are
hot-swappable.
Caution Both slots must be occupied either by two power supply modules or a power supply and a fan module.
Do not run the switch with an empty slot unless you are replacing a faulty power supply or fan module.
Running the switch with an empty slot triggers an alarm.
Each power supply module contains three fans. The switch can operate safely if one fan fails. A fan
failure triggers an alarm. When a fan fails, replace the power supply module immediately.
See Chapter 3, “Installing and Removing AC and DC Input Power Supply and Fan Modules,” for
instructions on installing the AC and DC input power supply and fan module. See Appendix A,
“Technical Specifications,” for voltage and other specifications.
Power Supply Module LEDs
The power supply module LEDs show the status of the power supply modules. Figure 1-5 applies to both
AC and DC input power supply modules.
