ONFIGURATION
Prior to turning on the IRD, ensure that all cabling is correct. Ensure that the
unit is connected to the mains power supply and grounded according to local
instructions.
2.4.1. Electrical Power Connection
The IRD is powered by AC power. Connecting the AC power cable to the IRD AC
connector makes the ground connection to the IRD.
When the IRD is rack-mounted, the jackscrew must be connected to the rack
housing, which in turn should be correctly grounded.
For a view on the jackscrew, see Figure 2-2.
