CAUTION:
There is a danger of explosion if the battery is incorrectly replaced or handled. Do not
disassemble or recharge the battery. Do not dispose of the battery in fire. When the battery is
replaced, the same type or an equivalent type recommended by the manufacturer must be
used. Used batteries must be disposed of according to the manufacturer's instructions.
Return the board to Intel for battery service.

Operating Temperature

The ZT 5504's heatsink allows a maximum ambient air temperature of 50°C with 200 LFM
(linear feet per minute) of airflow. External airflow must be provided to the ZT 5504 at all times.
Refer to the "Electrical and
refer to the topic "Temperature
on monitoring the processor temperature.

Reliability

MTBF: 14.6 years (excluding on-board hard disk drive)
MTTR: 3 minutes (based on board replacement), plus system startup
