only 1 strip of 8 work

[rgbmike]

I've loaded the basic test program into teensy3.2. I have 8 strips of ws2812 of 16 pixels each.
only strip 5 seems to be working.
I've moved the cat5 wire pair to a different strip and it works fine.
Also, replaced the octows2811 with another one with the same results.
any ideas as to why only 1 of 8 strips work?
TIA Mike

const int ledsPerStrip = 16;

DMAMEM int displayMemory[ledsPerStrip*6];

const int config = WS2811_GRB | WS2811_800kHz;

OctoWS2811 leds(ledsPerStrip, displayMemory, drawingMemory, config);

const int LEDPIN = 13;
byte bLoop = 0;

void setup() 
{
  Serial.begin(9600);
  //flash ledpin 3 times on setup
  pinMode(LEDPIN, OUTPUT);
  for(bLoop = 0; bLoop < 3; bLoop++)
  {
    digitalWrite(LEDPIN, HIGH);
    delay(1000);
    digitalWrite(LEDPIN, LOW);
    delay(1000); 
  }
  Serial.println("Starting leds");
  Serial.print("numpixels=");
  Serial.println(leds.numPixels());
  leds.begin();
  leds.show();
}

Found the problem. Always check your rj45 wiring. mine was not correct the data and grounds were switched.
All is working n
