OptiView TM Series II
Getting Started Guide
The LEDs on the front of the analyzer represent the following conditions:
Link - Indicates one of five conditions given below.
green solid = link present with fiber or twisted-pair MDI connection (analyzer
!
receives on 3, 6 pair)
amber flashing = cable or wire mapper present, but no link present
!
amber solid = link present with MDI-X connection (crossover, analyzer
!
receives on 1, 2 pair)
red flashing = no cable or no link present on fiber
!
red solid = an over voltage condition has been detected such as being
!
connected to an ISDN line
Transmit - Indicates the analyzer is transmitting packets. Packets are transmitted
while running Traffic Generator, and routinely transmitted by the analyzer
discovery process. The analyzer communicates with devices to determine their
device type and identity. The LED will flash faster as more transmit activity from
the analyzer occurs.
Collision - Indicates that collisions have been detected by the analyzer on the local
network. As more collisions occur, the LED flashes faster.
Errors - Indicates that errors have been detected on the local network. Errors
include CRC alignment errors, undersized packets, oversized packets, and jabbers.
Utilization - Represents traffic at the point where the analyzer is connected (local
traffic). Ten LEDs indicate utilization in 10 percent increments. The first five
LEDs (from left-to-right) are green, followed by three amber LEDs (indicating
more traffic), then two red LEDs (indicating very heavy traffic).
The green Utilization LEDs also flash during cable testing. Do not
disturb the cable while these LEDs are flashing or the measurement
results may be invalid.
