This chapter explains how to use the LANVIEW LEDs to help
troubleshoot network problems.
3.1 LANVIEW INDICATORS
LANVIEW is a built-in diagnostic and monitoring system.
Incorporated into the entire Cabletron Systems product line,
LANVIEW lets you quickly scan a series of LEDs to get a sense of
network activity and help you isolate physical layer problems. This
section explains each of the MR-9000TPT LANVIEW LEDs.
Power (PWR)
When lit, this green LED indicates that the MR-9000TPT is receiving
power. The On/Off switch is located on the back of the unit, next to
the power cord connection.
Transceiver Power (XCVR PWR)
When lit, this green LED indicates that the MR-9000TPT is providing
power to the transceiver connected to port 9, the repeater's AUI port.
Jam (JAM)
When this red LED flashes, the repeater is propagating a collision
from the segment where the collision occurred, to all segments
connected to the repeater. The repeater transmits the jam pattern
(1,0) to all segments when it detects a collision on any segment.
