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 66: G650 Cabinet Environmental Hardware Components on page 824 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.
These leads are labeled Major and Minor alarm. The designation of major or minor refers to the
lead, not to the severity of the alarm associated with the connection. For example, the major
lead can be administered as a major, minor, or warning alarm, and the minor lead can be
administered as a major, minor, or warning alarm. Analog line ports can also be administered as
external device alarms in the same mer.
If the External Device Alarm feature is enabled on the change system-parameters
customer-options form, the alarm level and the text string for the alarm condition for each
external alarm lead can be administered on the SAT screen using the
add eda-customer-alarm command. The alarm leads are tested using the
test eda-external-device-alrm location command.
If the External Device Alarm feature is not enabled on the change system-parameters
customer-options form on the SAT, a contact closure to ground for the Major Alarm lead will
generate a Major alarm for EXT-DEV, and a contact closure to ground for the Minor Alarm lead
will generate a Minor alarm for EXT-DEV. The alarm leads are tested using the
test environment location command.
