Power Supply Features
The Cisco ME 3400E-24TS-M and Cisco ME 3400EG-12CS-M support two power supplies, either AC
or DC. The switch runs with one power supply, but you should replace a switch that has a failed power
supply as soon as possible to maintain redundancy.
See Chapter 3, “Installing and Removing AC- and DC-Power-Supply Modules,” for instructions on
installing the AC- and DC-power supplies. See Appendix A, “Technical Specifications,” for voltage and
other specifications.
