Connector Pinouts

This section describes certain I/O interface connectors of the xSeries 343 server.

Alarms

The alarms port interface is a standard DB15-pin connector (see Figure 34). This connector allows remote display of alarm conditions. Each alarm (Major, Minor, Critical and Power) is the output of a STDT relay contact. A common contact with normally open and normally closed connections is included. Power alarm has just a common and normally open contact outputs. The major and minor alarms contain external reset circuits. Table 12 gives the pinout of the alarms connector.

Note

Do not apply more than 60 Volts (maximum) to any pin or combination of pins on the Alarms connector.
