Why do the Quasar module network connections need to loop back to the distribution board?

Updated 4 months ago by Bryan Jones

SCOPE

This article applies to the Quasar Console (surface) and the internal network wiring.

DESCRIPTION

Some people have notices that in the Quasar console, each module is wired together but then the last module is looped back to the second port on the distribution board. Why? And, is this required?

THE ANSWERS

Required? No. However, this is the recommended configuration and how any factory configured units will be built.

There are two reasons why the last module in any Quasar Console frame it wired back to the distribution board.

First (and primary) this is for redundancy reasons. It allows for the second port to be looped to a second network switch.

Note that Spanning Tree for Access ports must be properly configured on your Cisco switches BEFORE plugging in the second port. Spanning Tree is a method of blocking ports that are used for redundancy until they are needed. While many switches have Loop Detection, this is not the same thing.

The second reason for looping the last module back is that it allows for a convenient place to hook up a laptop or other computer for configuration purposes, however, this port is NOT designed to handle any AoIP traffic, but only TCP control packets, and therefore it should never be connected to xNodes or IP-Driver enabled computers. This should be used only for modules (like a split Quasar frame) or a configuration PC.
