AC- and DC-Power Input Connectors
The Cisco ME 3400E-24TS-M and the Cisco ME 3400EG-12CS support combinations of power-supply
modules: two AC, two DC, or one AC and one DC. The two AC- and one DC-power connectors on the
front panel accommodate the mixture of AC- and DC-power-supply modules. The DC-power connector
has the standard A and B feeds for DC redundancy. See Chapter 3, “Installing and Removing AC- and
DC-Power-Supply Modules.”
Alarm Input Port
The switch supports four alarm inputs. The alarm input is a dry-contact alarm port. Use the CLI to define
each alarm input to respond to a normally open or closed dry-contact closure and to define the alarm
severity as minor, major, or critical. When a condition triggers an alarm, the console displays an alarm
message, and the corresponding Alarm LED responds (see the “Alarm LEDs” section on page 1-11).
