Power Supplies
Two power supply types are used in the Trinix routing family, one type
for the 128 chassis and another for the 256 and 512 chassis. Both types,
which share the same feature set, are OEM products. The power sup-
plies differ primarily in power delivered, size, and weight.
The 128 and 256 chassis are designed for two power supplies. The
optional (and recommended) second supply provides redundancy and
increased reliability due to “load sharing” - both supplies work less,
creating less strain and decreasing the likelihood of failure of either
unit.
In AC power applications, the 512 chassis is equipped with two power
supplies mounted in a separate chassis. For redundancy, space is pro-
vided for two additional supplies (recommended). The 512 power
supply chassis may be mounted above or below the main chassis,
depending on video cable routing requirements (or weight distribution
requirements).
All power supplies are front loading and hot swappable and each has
its own fan for cooling. Automatic line sensing technology is used to
adapt the supply to all major power standards throughout the world.
The back panel of the chassis provides a separate AC connector for each
supply and a third connection for a 48 VDC input.
The power supplies each deliver 48 volts to all components and the
individual components convert down the voltages for their particular
need.
For additional redundancy, it is possible to operate the router with a
combination of internal power supplies and a external DC power
source.
