2-54 Feature Upgrade Procedure
6. Operate the INITIALIZATION (SW1) to the ON (right) position.
7. Restore system power.
8. Observe the CPU/Power LED. After approximately 4 - 6 sec., the LED should begin to
flash.
9. If the LED remains unlit or lit without flashing, repeat the above steps from Step 3.
Once the power up sequence is complete, DEFAULT DATA is loaded and the system
should be fully operational.
Feature Upgrade Procedure
Use the following procedure to upgrade the DHS system Feature Package software. Once
the upgrade is complete, the system must be initialized to assure proper operation.
1. Disconnect system power and remove the KSU cover by removing each of the 4 front
cover screws located at each corner.
2. If an Option Module is installed it must temporarily be removed to gain access to the
system software EPROM socket (U9).
3. Use the diagram (refer to Figure 2-29: DHS Components ) and locate the system
software EPROM socket U9. Observe the orientation of the notch at one end of the
EPROM so that the new EPROM is installed with the same orientation.
4. Using an IC extractor tool, remove the DHS software EPROM from the U9 socket.
5. Carefully remove the new software EPROM from its packing material and inspect for
damage (if any damage is noticeable please contact Vodavi Customer Service).
6. Install the new EPROM into the vacated U9 socket with extreme care so that no
EPROM pins are bent when inserted. The EPROM MUST be inserted such that the
notch is oriented at the top of the chip when in place (same orientation as the
previously removed chip).
7. Replace the Option Module if removed in Step 2.
8. Following proper power up and initialization, the system should function properly
with the new Feature Package software features operational. All specific customer
database data must be re-entered to customize system operation for use.
Refer to
Chapter 7, Maintenance/ Troubleshooting
, for further assistance if power up
cannot be activated.
Any handling of system integrated circuits must be done in a static controlled environment.
Please use satisfactory static preventive practices while handling system components and
while working on the system KSU with cover removed. (USE A STATIC WRIST STRAP!)
