UTStarcom MSG2000 User Manual

Preliminary

It is important to note that the fabric switch manager is part of the payload power 

domain. Therefore, the fabric switch and XLRs only start after the CNODE signals 

the fabric switch manager to power on. 

The CNODE signals the fabric switch manager to power on through a daemon, 

which runs a script that configures the fabric switch when the payload domain is 

activated. The daemon also monitors the fabric switch for proper functioning. For 

example, if a link is disconnected and reconnected, the switch responds appropri-

ately and the link continues to work uninterrupted. 

The fabric switch may also be custom configured to do things such as change traffic 

flow, handle VLANs, and direct certain packets to specific boards or payloads. A 

detailed description of fabric switch configuration is provided later in this 

document.
