Rear Panel
The rear panel on the Cisco ME 3400E-24TS-M and the Cisco ME 3400EG-12CS-M has two
power-supply slots for installing the removable power supplies and a ground connector. See Figure 1-9.
The switch can operate with only one fan. For maximum efficiency, at least two of the four fans should
be operational in a warm environment. A fan failure triggers an alarm. When a fan fails, replace the
power supply immediately.
The rear panel on the Cisco ME 3400EG-2CS-A has a fan exhaust, a ground connection, and an
AC-power connector (Figure 1-11).
