Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies all of the IMC-21GA’s power needs.
Communication Connections
RJ45 Ethernet Port Connection
The IMC-21GA has one 10/100/1000BaseT(X) Ethernet port located on
the front panel to connect Ethernet-enabled devices.
When connected to a 10/100 Mbps Ethernet port, the pinouts and cable
wiring diagrams for both the MDI (NIC-type) and MDI-X
(HUB/switch-type) ports for both straight-through and crossover
Ethernet cables are:
