E4G-200 Series Alarms Interface
The alarms interface for both the E4G-200 and E4G-200-12x routers is implemented as a DB-15 female
connector. This interface relays alarms to an external device (output alarms) and monitors alarms from
an external device (input alarms). The alarms are controlled from the ExtremeXOS software.
The alarms interface provides two input alarms and eleven output alarms. Input alarms can be
configured to monitor alarms from an external source and raise a trap or flag, or to be an input source
to clear Minor or Major alarms. The output alarms can be connected to an external visual or an audible
interface. The output alarms can be either persistent or non-persistent. For information about
configuring alarms, refer to the ExtremeXOS Concepts Guide.
For details about the connector, see “E4G-200 Series Connector Pinouts” on page 126.
E4G-200 Series Power Supply
Both the E4G-200 and E4G-200-12x routers have an integrated DC power supply with dual feeds on the
front panel. Power feed A can be connected to one power source and power feed B can be connected to
a different power source to provide protection should either source of power fail. The power supply is
not field-replaceable.
The back panel of the E4G-200 and E4G-200-12x router provides an alternate attachment point for the
grounding lug.
