Trinix Asymmetrical Power
Supply Configurations
Introduction
The Trinix Asymmetrical routers use external power supply modules,
which reside in a 1 RU power supply frame. Each of these frames can house
up to four power supply modules. The power supply modules are moni-
tored by means of I
2
C links.
The number of power supply frames, power supply modules, and I
2
C links
can vary depending on the model of the asymmetrical router that is used
and the redundancy configuration. This section provides the configuration
guidelines for the interface, connectivity, and monitoring of the power
supply modules.
The External Power Supply Frame
The Lineage Compact Power Line Shelf (see Figure 135 ) is the current
power supply frame that is used for the Trinix Asymmetrical routers.
Figure 135. Lineage Power Supply Frame
The Lineage power supply frame supports up to four power supply mod-
ules. The power supply frame sets the output voltage of each power supply
module to 48 VDC.
