Refer to Start Up

Procedure



Visual Inspection

Visual Inspection purpose is to insure all installationand wiring work were done in proper way

1-Check the appearance and label

2-Check the ODU &Antenna frequency based onfrequency plan

3-Check the fixing way of rack and equipment

4-Check the cable connection and power Polarity

NESIC CAIRO



Please refer to your equipment Instruction manual

2-DC input Voltage value & Polarity 1-Check the DC input voltage in IDU is connected correctly

and in the accepted range

Power requirement: +/- 20 to +/- 60

Or (+/-20 to +/- 72)

NESIC CAIRO

Confirm the

Polarity before

insert the power

Cable

+-



1-Never switch it Off before at least 30 sec2-Never connect or disconnect the IF Cable

while the equipment is powered On

3-Leave the equipment to warm up

3- IDU Start up 1-Be sure the power cable and IF cable are connected in

Proper way

2- Carefully Poll out the Power On / Off toggle switch and put

in ON position.

2- To shutdown the IDU switch the toggle switch to Off
