CHAPTER 3
USING LANVIEW
LANVIEW is a visual diagnostic and status monitoring system
developed by Cabletron Systems. LANVIEW LEDs can help you
troubleshoot network problems such as open segments or FDCMIM
power problems. The following sections describe FDCMIM LEDs.
3.1
FDCMIM STATUS LEDS
The FDCMIM has two LEDs, PWR and FNB, that show MIM status.
PWR (Power)
When ON, this green LED indicates that the FDCMIM is getting
power from the MMAC.
If the MMAC power is ON, but the FDCMIM PWR LED is OFF,
remove the FDCMIM from the MMAC and check for bent or broken
pins on the FNB (backplane) connectors. If you find any damaged
connectors, do not re-install the FDCMIM. Contact Cabletron Systems
Technical Support.
FNB (Flexible Network Bus Status)
This multi-state LED can indicate the following:
Green
The FDCMIM connects to one or more FDDI
MIMs through the MMAC FDDI bus.
Amber
Management has disabled this module.
Note: You must use an FDMMIM in conjunction with the FDCMIM to
have management available. If you do not have an FDMMIM in the
hub, an amber LED indicates an FDCMIM hardware problem.
