Power Box Test

Power terminals resistance values (Note: external powercable not connected, because there is not main power switch

on the power panel)

Switch OFF: the resistance between NEG1(-)/NEG2(-) and

RTN1(+)/RTN2(+)/PGND should be infinity;

Switch ON: the resistance between NEG1(-)/NEG2(-) and

RTN1(+)/RTN2(+)/PGND should be tens K,if the resistance

less than 20, short circuit happens and must be eliminated;

Check the metal piece between (BGND &PGND) terminals


11/62


Cable Check

All cable including power cable, GND cable, relay cable and

tail fiber should be nicely put in order and be labeled correctly)


12/62


Boards Appearance Check

You must affirm:

All bolts on top and bottom of boards should be tightened and not falling

off.

The metal reeds on the two sides of boards should not be warped

Spans of GXCS/CXL1/4/16 should be buckled (the jiggle switch should be

closed)

All boards are screwed well and plugged to the end

Anytime when in contact with boards, you should wear anti-static wriststrap or anti-static glove

The RJ-45 interface on AUX should not be mis-plugged


13/62


Dont Forget!

Engineering document single station part, must

be done for each sites

Be sure all power supply switches are OFF

during the hardware check
