RADWIN 1000/2000/5000 User ManualVersion 2.6.50p 3-11
The purpose of the LEDs is shown in table 3-2 below:
 To mount an IDU (using figure 3-8 above):
1. If the rack already holds other equipment, ensure that it is properly
grounded.
2. Attach the rack mounting brackets (K) to the IDU.
3. Bolt the IDU into an empty slot in the rack, ensuring that it sits securely.
4. Ground the IDU to the rack using grounding lug I. The IDU should be left
permanently grounded.
Connecting power to the IDU
The IDU-C has redundant power connection circuits (items G and H in
figure 3-8 above). An enlarged schematic of the power connectors is
shown in below:

Note

using the four screw holes on each of its sides.
