Memory Module installation or replacement
Note: The Memory Module has a proprietary formatting scheme — do not attempt to install a non-ESI drive.
Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the CompactFlash Memory Module will require that the ESI-50L be taken out of service.
All of the system’s configuration data and customer recordings are stored in the Memory Module.
Replacing it, therefore, requires re-programming and re-recording, unless you have previously performed a backup
using ESI System Programmer software. (Prompts stay intact, however.)
Note: Be sure to observe all proper procedures regarding the prevention of electrostatic discharge (ESD) when
performing the following procedures; otherwise, circuit boards may suffer damage.
Install the Memory Module
1. Open the lid of the cabinet (you must remove the screw
on the top that secures the lid).
2. Power down the system.
3. Plug the Memory Module into the J11 connector on
the main board (see diagram, right).
4. Secure the lid to the KSU.
Remove the Memory Module (if replacing)
1. Open the lid of the cabinet (you must remove the screw

2. Power down the system.
3. Remove the Memory Module from the J11 connector on the main board (see diagram, above).

LED functions
The unit's various LEDs are designed to provide visual feedback as follows:
• The Power LED is located on the right side of the Base Cabinet, and is illuminated when power is being
applied to the system. This LED blinks periodically to indicate that the main processor is operational.
• The Port LEDs are located above their respective connectors on each installed port card. Each LED is
illuminated when any port on its associated port card is in use.
Note: Disconnecting a connector when its respective LED is lit will disconnect any of its ports that are in use.
Upon power-up, approximately five minutes are required for the system to configure. The Power and Port LEDs
will blink three times to indicate that the power-up sequence has been completed.
