    Because the LGB5028A and LGB5052A switches comply with the IEEE 802.3 standard, if a device connected to the switch has a fixed configuration at full-duplex, the device will not connect correctly to the switch. The result will be high error rates and very inefficient communications between the switch and the device.

  • Page 33: Contacting Black Box

    Check connections between the switch, the power cord, and the wall outlet. System LED is OFF Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com for assistance. Verify that the switch and attached device are powered on. Make sure the cable is plugged into the switch and the corresponding device.
