By utilising advanced PSU circuit topology and the latest signal switching
technologies,
Freeway
offers a very compact router with low power dissipation,
ensuring fit and forget
reliability.
For extra security, each frame has provision for
two PSU modules so that one may act as a backup in the event of a PSU fail. The
high-speed converter technology in the PSU is monitored by two on-board
microprocessors that assess the condition of the mains and of the supplies
leaving the power unit
.
Should any of the PSUs vital-signs show a warning
condition these are monitored and. if appropriate, an external warning alarm may
be activated.
Freeway
PSUs may be withdrawn from the unit from the front and a
replacement hot-plugged; thereby ensuring continuous service. For details, see
Chapter 3.
