CHAPTER 14
TROUBLESHOOTING
This chapter includes information for troubleshooting network and EMM-
E6 operational problems. The following sections describe the EMM-E6’s
LANVIEW LEDs, provide a troubleshooting checklist, and explain how
and when to reset the EMM-E6.
14.1 USING LANVIEW
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.
