I have tried all my possible way .. but still i am unable to get the display oy cisco-3750.

kindly suggest any other technique or method.

When I powered ON the C-3750 it works. and thier FANS are working properly.

When ever I Power UP the SWitch while pressing mode button

It LED status on sys LEd is green

all other LEDs (pps, master stat, dup & speed)show light . and at the en only sys led remain green and thier is no display on my system .. although i have treid diff system and console to quit the dout on cable or sysytem.

waiting for ur replay.

Thanks and regards

)-Verify Switch POST Results

2)-Monitor Switch LEDs

3)-Verify Switch Connections

4)-Monitor Switch Performance
