AsantéHub 2072 Network Management Module Installation Guide

Name

Function

 

 

Hub Status LEDs

Provides warning and packet collision data about

(bottom row of 8 LEDs

the segment (not the module); the first four are

per segment)

warning LEDs, the second four provide the total

 

percentage of packet collisions occurring at any

 

instant on Segment 1 or Segment 2.

 

LC - Late Collision. A collision which occurs after

 

the 64 byte Collision window

 

MC - Misaligned/CRC. This received data frame

 

was not an integer multiple of eight bits (or one

 

byte).

 

RF - Runts/Fragments. This frame is greater than

 

two bytes and less than 64 bytes, has a Start

 

Frame Delimiter, and has a bad Frame Check

 

Sequence (CRC) error).

 

SM - Short Event/Missing SFD. This data frame is

 

less than ten bytes and does not have a Start

 

Frame Delimiter.

Out-of-Band LED

Flashes when Out-of-Band is in use with the AMS

 

Link (RJ-45) only. Note: This only functions when

 

the NMM is in operational mode.

SETUP LED

Lights continuously to indicate DB-9/RS232 is

 

being used for setup (DIP Switch 2 in DOWN

 

position).

 

Flashes when management station running AMS is

 

communicating through the DB-9/RS232 (Out-of-

 

Band) connection.

ASANTEVIEW OUT-OF-

Terminates the Out-of-Band daisy-chain. The end

BAND TERMINATION

hub in the chain must be terminated. If only one

(DIP Switch 1)

hub is in the chain, set this switch to the DOWN

 

position.

RS232/AMS LINK

Indicates (switch is set to UP position) RS232 is

CONFIGURATION

being used with AsantéView Out-of-Band.

(DIP Switch 2)

Switch set to DOWN position indicates RS232 is

 

used for terminal mode or when AsantéView Out-

 

of-Band is connected using the RS232 port on the

 

NMM.

Select Slot button

Lets you select a particular module and then use

 

the Change Segment button to place the module

 

on a different segment.

Change Segment button

Lets you place the selected module on Segment 1,

 

Segment 2, or neither segment.

Segment 1 LED

Lights to indicate that the module is currently on

 

Segment 1 of the backplane. Segment 1 is the

 

default setting. If both Segment LEDs are off, the

 

module is not connected to either of the two

 

segments.
