Check the Status LEDs
When power is applied, the green LED labeled “STATUS” will light. This indicates that the system is OK and
that power is applied. Once the T-600 boots, the yellow “BEAT” (heartbeat) LED will begin blinking, with a
typical rate of about 1 Hz. Blinking should begin within 30 seconds after power is applied.
If after applying power, the STATUS LED goes out, or if the BEAT LED comes on (steady) and stays lit longer
than two minutes, contact Systems Engineering for technical assistance. See also the
About the Battery
The T-600 is provided with a custom 10-cell NiMH battery pack mounted to the unit (under the cover). This
battery allows the JACE to continue operation through very short power bumps (a few seconds in duration). If
a longer power outage occurs, the battery provides enough run time for the T-600 to backup data and then
shutdown. Typically, this is one minute. Shutdown occurs automatically, after data is backed up to on-board
flash memory.
The T-600 charges the battery during normal operation, until fully charged. Typically, the charge operation
completes within 18 hours. Following a power outage, the battery is charged again, as necessary. The power and
battery circuitry is monitored by a station running on the JACE (via the PowerMonitorService). Station alarms
are generated whenever primary power is lost, or if the battery is uncharged or unable to hold a sufficient charge.
The battery should be replaced approximately every three years, or more often if the unit is in a high temperature
environment.
Note
A NiMH battery characteristic is to lose charge if not left in charge mode (trickle charge). Leaving the
battery unconnected, or in the unit powered off will cause the battery to fully discharge in a matter of
weeks. Note that in the case of a new T-600, it ships from the factory with a completely discharged
battery. Therefore, allow at least 18 hours for the battery to charge if it has not been in a powered unit.
