TESTING AND LANVIEW
Page 3-2
At least 100 packets should be sent and received with no errors.
The packets will be received from and sent back to the LAN-MD
acting as the
SERVER .
When the applicable segment(s) connected to the THN-MIM have
successfully completed these tests, the segments are ready for normal
operation. If any failures were noted, please contact Cabletron Systems
Technical Support.
3.3 USING LANVIEW
The THN-MIM uses Cabletron Systems built-in visual diagnostic and
status monitoring system, LANVIEW. A network troubleshooter can
quickly scan the LANVIEW LEDs to observe network status, diagnose
network problems and identify which node or segment is faulty.
The following discusses the function and the purpose of each
LANVIEW LED on the THN-MIM.
NOTE: There is one Port OK ( POK ) and Receive ( RCV ) LED for each
port on the module.
Port OK (POK) LED
When lit, this LED indicates that the port is connected to the network.
If the LED is not lit, one of the following conditions exist:
a. The occurrence of 33 consecutive collisions on the attached
segment or the collision detector was on for more than 2.4 ms.,
causing the port to be electrically disconnected from the MMAC
b. The port was turned off by Local Management
c. The port has yet to receive a valid data packet after
segmentation or upon power up.
Receive (RCV) LED
This LED normally flashes on and off to indicate that the MMAC is
repeating the data packet. The rate at which the LED flashes will
increase as network activity increases.
