Power

All E-series routers provide a power architecture that distributes redundant –48 VDC feeds through the router to each line module, SRP module, and fan module where DC-to-DC converters provide local conversion to the required secondary voltages.

The ERX-310 router is available with either DC or AC power inputs. The AC-powered version can be configured with one or two hot-swappable power supplies for optional redundancy. (See Figure 5 and Figure 6.) The power supplies convert AC power to internal –48 V redundant DC feeds that are then distributed through the router.
