Power Supply Features
The Cisco ME 3400E-24TS-M and Cisco ME 3400EG-12CS-M support two modular redundant power
supplies, either AC or DC. The switch requires a single power supply to operate. If a failure occurs with
a power supply, replace only that failed power supply 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.
