Test required for 1% of the product:

Take the printout of BOM of Active Hub of same revision number which is written on the P.O. Now perform the following tests.

Following test needs to perform on Main controller PCB (PT0012M). Must take out 1 unit randomly from the burn In Test and
do the following test.

Component Verification

1- IC’s / Diodes Verification

IC’s:

All IC’s numbers are written on the top of IC, verify all the IC’s with the PLM BOM.

Diode:

All diode numbers are written on the case diodes, verify diode number with the PLM BOM.

2- Resistor Verification

For all resistor needs to measure the resistance with the help of multi meter and compare it with the BOM. Don’t
need to de-solder, the value found on the meter will be approximate.

For Resistor R58 on main controller PCB, they are specified for 1% tolerance. Hence de-solder them and take them
out. And Measure with the multi meter. The value should be

R1 = 120 ohms (In between 118.8 ohms to 121.2 ohms)
