Real-Time Clock
An internal real-time clock with battery backup provides the system software with time of day on system
power up. This allows the system to verify the validity of the certification authority (CA) certificate. The
Cisco IAD2801 has a socketed lithium battery. This battery lasts the life of the router under the operating
environmental conditions specified for the router, and is not field-replaceable.
Note
If the lithium battery in a Cisco IAD2801 should fail, the router must be returned to Cisco for repair.
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Warning
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according
to the manufacturer’s instructions.
