A super capacitor in the processor module provides backup power for the system’s clock and its memory in case of power failure or system shutdown. The super capacitor retains data for four to five days.

PCMCIA Memory Card

The processor includes 4 MB of on-board memory that can be erased and written over multiple times. A PCMCIA memory card can be used to install or upgrade the system software into this memory. A memory card can also be used to back up and restore system programming.

There are different types of memory cards, each about the size of a credit card. Their labels indicate contents and function. Described below are three types of PCMCIA memory cards that you may encounter. For more information, see System Programming or contact your Lucent Technologies representative.
