Configuring an alarm input

The 7210 SAS-D, 7210 SAS-Dxp, 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C do not support alarm contact inputs; instead, they provide an option to configure the console port as an alarm input pin. A single alarm input pin can be enabled for use with the console port, allowing operators to monitor external events and alert the operator.

You can configure generation of events when alarm input pins transition between the open and close states. For each generated event, you can specify the following:

• action associated with each state transition

• severity associated with each state transition

• log message associated with each state transition

The RXD and TXD pins of the console input is used to provide a single alarm input pin functionality. The RXD and TXD pins of the console port is used by software to detect external events. The operating system detects an open or closed circuit, triggers an alarm, and logs it when an event is detected.

By default, the console port does not provide alarm input pin functionality. The CLI command configure>system>console>use-console-alarm-input is used to enable the use of console port as an alarm input pin. After this command is executed, the console port can no longer be used as a console port, and the system generates a log message to convey this restriction. Additionally, the user must configure the alarm-contact-input parameters for the console by using the CLI command config> system>alarm-contact-input console-1.
