System Alarm Contact Inputs
The 7210 SAS platform hardware supports alarm contact inputs that allow an operator to monitor
and report changes in the external environmental conditions. In a remote or outdoor deployment,
alarm contact inputs allow an operator to detect conditions, for example, air conditioner fault, open
door.
An operator can configure generation of events when alarm contact inputs transition between the
open and close states. For each generated event, the operator can specify the:
• Action associated with each state transition.
• Severity associated with each state transition.
• Log message associated with each state transition.
Configuring an Alarm Input in 7210 SAS-D and 7210 SAS-K devices
Unlike the 7210 SAS-E, the 7210 SAS-D and 7210 SAS-K does not support alarm contact inputs,
instead, it provides 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.
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 a close circuit and 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, user
needs to configure the alarm-contact-input parameters for console, by using the CLI command
configure> system> alarm-contact-input console-1.
NOTE: The user must enable a telnet session with the node, before enabling console as an alarm-
input. Once the alarm-input functionality is enabled, the user can configure the alarm-contact-
input <no shutdown> using the telnet session.
