Comdial Dxp General System Description Release 10a Instructions Manual

							Up-Grading Your System To
Software Release 10A
Up-grading to software release 10A requires that you perform the following detailed operations in the
sequence that they appear in the following pages of this publication. If you need detailed procedures for
doing these operations, refer to your DXPSystem Hardware InstructionsandProgramming Instructions
and Recordsservice binders and to GCA40–182,Understanding The VMMI.
Converting The Database
Storing The Current DXP Database
Employ a personal computer with an XMODEM communications program and use the current embedded
MMI programming method to store the current DXP database to the computer’s hard drive. The saved
database can include any or all of the following data: system information, station parameters, line
parameters, toll restriction and automatic route selection parameters, and system speed dial numbers but it
does not include the SMDA/SMDR records. If you need these SMDA/SMDR records, you must make a
printout of them before you perform the database storage. This is necessary because this save/restore
feature does not record the stored records and they will be lost.
Once you store the current database disconnect your computer from the DXP.
Converting The Current DXP Database
With your computer disconnected from the DXP, convert the current database to a 10A database.
1. Obtain a copy of revision 9A or later PCMMI programming software and load it on your computer.
(Remember, you can always down load the latest PCMMI software from the Comdial Technical
Services Bulletin Board by calling 1–804–978–2583 or from the Comdial home page on the World
Wide Web by connecting at: http://www.comdial.com/ ).
2. If the stored database is not at software release 9A, use the revision 9A or later PCMMI to convert the
current DXP database to a software release 9A database.
3. Use the revision 9A PCMMI to down-load and store the software release 9A database to your
computer’s hard drive.
4. Load the new VMMI programming software on your computer, and use it to translate the stored  data
base to a 10A database.

							Installing The RAM Card And Software Card
Turn off the power to the DXP, and install both the RAM card (DXRAM–EXPC.) and the software
memory card (DXPSW–DLRC) on the central processor unit (DXCPU–68K) circuit board of the DXP
digital communications system.
Preparing A Static-Safe Work Area.
CAUTION
Electronic circuit boards are susceptible to damage caused by electrostatic discharge and  must  be
handled accordingly. Refer to the Comdial publication IMI01–005,Handling Of Electrostatically
Sensitive Components,for general information. Specific handling precautions are also included in this
installation instruction. The expanded memory card (DXRAM–EXPC) and the system software memory
card (DXPSW–DLRC) are supplied in static protection bags. Do not open a static protection bag prior to
installation time.
When servicing electronic circuit boards, it is a good practice to do so at a static-safe work area prepared
ahead of time for this purpose. The illustration details a typical static-safe work area.

							Installing The Cards
1. Loosen the retaining hardware and remove the front panel from the DXP main cabinet.
2. Turn off the AC power switch, and disconnect the AC power cord from the AC outlet. Disconnect the
cable of the optional battery back-up from the main cabinet power supply.
3. Place a conductive mat in front of the cabinet area and ground the mat to a good earth ground (the
third wire ground of the AC power line is an acceptable grounding point). The grounded conductive
mat will provide a safe static electric discharge path.
4. Install the static discharge wrist strap (supplied with the main cabinet) on your bare wrist; adjust it for
a snug fit. Be sure that the strap is touching bare skin and is not isolated by clothing.  Connect the
wrist strap cord between the wrist strap and an AC or earth ground.
NOTE: With the common equipment in the installed position, the ground lug on the side of the
cabinet is an appropriate grounding point since it should have a heavy ground wire
connected between it and a good earth ground.
5. Locate the DXCPU–68K circuit board, loosen the retaining screws, remove it from the DXP main
cabinet, place it in a static protection bag, and transport it to the static-safe work area.
6. At the static-safe work area, with your wrist strap in place, remove the DXCPU–68K circuit board,
the new DXRAM–EXPC. expansion memory card and the new DXPSW–DLRC software memory
card from their static protection bags.
7. Refer to illustration and remove the currently installed memory cards from the DXCPU–68K board.
8. Orient the DXCPU–68K board and the new memory cards as shown in the illustration, and attach
them with the supplied hardware. (The screws and standoffs between the cards are essential to ensure
proper grounding.)
9. Place the old memory cards in static protection bags and save them for later return for credit. Place
the DXCPU–68K board and newly installed memory cards into a static protection bag and transport
back to the DXP main cabinet.
10. With your wrist strap properly grounded, remove the DXCPU–68K circuit board from the static
protection bag. Orient it with the top and bottom guides in the main cabinet board cage, and press it in
firmly until the board edge connector properly mates with the backplane connector.
CAUTION
When pressing the DXCPU–68K board into place, press it only at the extractor lever locations. If you
apply pressure at other locations, you may damage the board assembly.
11. Make a final inspection to ensure that the DXCPU–68K circuit board is in the correct slot, oriented
correctly and mated properly; then install and tighten the supplied screws to secure it to the board
cage.

							Master Clearing The System
1. If you do not master clear the system, it is possible the DXP will not perform properly with the new
memory card. The DXCPU–68K board provides a method for the master clear to occur automatically
at the initial power up after you have changed or upgraded the software card. When you perform an
upgrade, you must execute the following sequence of events exactly as they are stated here:
2. On the DXPCPU–68K circuit board, set DIP switch 8 to its ON position. This step enables the DXP
to perform the master clear and is a required step; otherwise, the software upgrade will not occur and
the system will not operate.
3. Connect the AC power cord to the AC outlet and turn on the AC power switch. At power up, the DXP
automatically executes a master clear operation. Observe that the LED indicators on the
DXCPU–68K board, the DXSRV services board, and all installed station and line boards flash in a
random pattern during the master clear sequence. After the master clear sequence is complete, the
indicators on the DXCPU–68K and DXSRV boards turn on steady and the indicators on the station
and line boards wink ON for four seconds and OFF for four seconds.
3. After power up, set DIP switch 8 to its OFF position.
4. Press the RESET button on the CPU board to reset the system.
NOTE:The system performs the automatic master clear one time following the initial power up
after you have up-graded the software. It will not perform an automatic master clear
operation again after subsequent power ups. Because of this, you can leave DIP switch 8
ON if you wish. Leaving it ON will ensure that the DXP will always power up in a master
cleared and operational mode after you have performed a software upgrade. However,
by turning DIP switch 8 OFF, you prevent the DXP from becoming operational at power
up after you have performed a software upgrade. This is good because, should you forget
to save your database, it gives you an opportunity to reconsider your actions before the
DXP erases the current database.
5. Replace the front panel on the DXP main cabinet.
