4.3 The Enhanced Chassis -48V DC version (ECDC)
The 1RU Enhanced Chassis can house a maximum of 3 modules, and it is equipped
with two -48V DC 75W power supplies. The unit is forced air ventilated, the air flow
going from front to back. The maximum power consumption of the chassis with
optional modules is 75W. By default all connectors are located at the front of the unit.
The power plugs are located at the rear of the unit. The rack ears of the chassis may
be moved to provide for mid or rear mounting of the unit. The rack ears are designed
to support the weight of the unit.
4.3.1 Dual Power Supply
ECDC rear: two -48V DC connectors located on the the right.
The Enhanced Chassis (EC) is delivered with two -48V DC / 75W power supplies,
providing power redundancy. Each EC unit consists of a 1RU chassis with 3 option
slots. In normal operation load is shared between the two power supplies. If mains fall-
out occurs for one of the power sources or one of the power supplies fails, the power
supply still in operation will take the full load, seamlessly. This means that monitoring
operation will not be affected if one of the power sources fails. Power supply failure will
be indicated by a red LED located rightmost on the front of the chassis.
