EMM-E6 Installation Guide 4-1
CHAPTER 4
TROUBLESHOOTING
This chapter provides diagnostic and troubleshooting information.
4.1 USING 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.
