Connector Pinouts

This section describes certain I/O interface connectors of the cc3000 Carrier Grade Server.

Alarms

The alarms port interface is a standard DB15-pin connector (see Figure 31). 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 15 gives the pinout of the alarms connector.

CAUTION

Do not apply more than 60 Volts (maximum) to any pin or combination of

pins on the Alarms connector.
