Cabletron Systems THN-MIM manual Using Lanview, Port OK POK LED, Receive RCV LED

TESTING AND LANVIEW

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.

3.3USING 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.
