EXT-DEV (External device alarm)
G650
A TN2312BP IPSI, in a G650 with a carrier address set to A, has two alarm ports that connect to
external devices. An example of an external device is an uninterruptible power supply (UPS).
Refer to Figure 115: G650 Cabinet Environmental Hardware Components
on page 1959 for
further information.
Conditions can occur on the external device that close the contacts on the alarm leads. This
notifies the switch to originate an EXT-DEV alarm. One set of leads generates a major alarm,
the other set generates a minor alarm.
In this case, the designation of major or minor refers to the port, not to the severity of the alarm
associated with the connection. For example, the major port can be administered as a major,
minor, or warning alarm, and the minor port can be administered as a major, minor, or warning
alarm. Analog line ports can also be administered as external device alarms in the same
manner.
