CHAPTER 4

TROUBLESHOOTING

This chapter provides diagnostic and troubleshooting information.

4.1USING LANVIEW LEDS

The EMM-E6 uses the Cabletron Systems built-in visual diagnostic and status monitoring system called LANVIEW. With LANVIEW, you can quickly scan the EMM-E6 LEDs to observe network status or diagnose network problems.

NOTE

The STBY, RCV, XMT, and CLN LEDs are in a matrix, which provides these indicators for four of the EMM-E6 Ethernet channels. To read the LEDs, the vertical column indicates the interface or channel the LED designates, while the horizontal row denotes the condition or statistic being monitored.
