Introduction
Overview
The instructions are for the original Trinix DV-33128, DV-33256 and DV-
33512 routing switchers.
For Installation instructions for the newer NXT or Asymmetrical frames,
see Installation for NXT and Newer Frames
on page 35 . For more information
about these frames see the Trinix Installation and Service manual.
The TRX-PSFRM-TER-1RU product, sometimes referred to as a tertiary
power supply, is designed to supplement the Trinix DV-33128, DV-33256
and DV-33512 internal power supplies to provide increased backup protec-
tion. This product comprises 1RU chassis that can hold up to four 1200W
100-240AC, 50-60Hz power supplies (TRX-PSU-1200W) and a 3 meter
power cable that interfaces this 1RU chassis to the legacy Trinix chassis.
These packages can be used in various combinations with Trinix DV-33128,
DV-33256, and DV-33512 routers. This flexibility is shown in
Figure 1 on the
next page.
The power supplies are bussed together so that the power load is shared at
all times. If one power supply fails, the remaining power supplies on that
bus will continue to provide power. The failed power supply should be
replaced as soon as possible.
