Reformatting the RAM Disk
Follow the procedure below to test, format, and copy the standard databases onto the RAM disk:
[ ] 1.
Ensure that a backup of the current databases and voice prompts is available. The data
will need to be restored following the reformat procedure. Refer to the
Model 640
Operating and Programming Manual
(Part No. 025-9417) for details.
[ ] 2.
Verify that the ROM disk EPROMs (Part No. 601-0329) are version 2.01 or later.
[ ] 3.
Power down the paging terminal.
[ ] 4.
If this reformat coincides with a ROM disk software update, remove the current ROM
disk (Part No. 702-9389) and replace it with the new one.
If only the ROM disk EPROMs are being updated, remove the ROM disk. Then remove
the EPROMs from the disk and replace them with the new ones. The new chips should
be installed in U1-U4.
[ ] 5.
Verify that the BIOS version is 1.0 for the currently shipping V53 microprocessor (Part
No. 601-0696). The BIOS EPROM is located to the immediate left of the RAM disk on
the main processor board.
[ ] 6.
Install JP9 and JP10 on the main processor board. The jumpers are located together on
the right rear corner of the board, next to the ROM disk.
[ ] 7.
Power-up the paging terminal.
[ ] 8.
The front panel COM and MODEM lights (on the left) blink in the sequence shown in
Table 28.
