Comdial Dxp Plus, Fx Series Instructions Manual

							Installing the Cards in the DXP1.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

groundl&point since it should have a heavy ground w&e connected between it and a good earth
ground.
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.
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.
Refer to illustration and remove the currently installed memory cards from the 
DXCPU-68K board.
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.)
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.
When pressing the DXCPU-68K board into place, press it only at the extractor lever locations.
If 
YOLL apply
pressure at other locations, 
YOLL 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 DXP System
1.

3.
4.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:
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.
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.After power up, set DIP switch 8 to its OFF position.
Press the RESET button on the CPU board to reset the system.
NOTE:The system 
per$orms the automatic master clear one time following the initial power up after yolr 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 
LL~ in a master cleared and operational mode after Yost have pelformed a software upgrade.
However, by turning DIP switch 8 OFF, you prevent the DXP from becoming operational at power 
~1p after
YOLK have pellformed a sofrware 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.

							Understanding the VMMIGCA40-182Translating the DXP Database
You can use the VMMI to translate the database residing in a DXP to a format that is compatible with the
IOA software release. Before you can translate the database, you must convert it to a 9A software release
level as described in the paragraph titled Converting the DXP Database.
1.Select the VMMI program from the Windows menu screen.
2.From the VMMZ window, select the File pull-down menu.
3.From the File pull-down menu, select Open. System default conditions cause the VMMI program to search for all
*.DXP files in the VMMI directory; however, you may need to type the path location and DOS file name of the
DXP database that you wish to translate.
4.From the Open Data Base File window, select the database for translation, and OK your choice.
5.Select a file location for the translated database and OK your selection.
6.Select the destination program for the system to use. The Select Board Type window opens.
7.Use the Select Board Type window to describe the board configuration of the DXP database that you are
translating.
(a) Make a record of the DXP’s physical board configuration by entering product codes in the following table.

(b) Using your charted information, answer the prompts on the Select Board Type window. The prompts first asks
for all installed station boards beginning with the DXP’s left-most universal slot in the main cabinet. The
prompts then ask for all installed line boards beginning with the DXP’s left-most slot in the main cabinet.
When a slot in the original DXP contains an auxiliary board, select the No Board response.
When the prompt asks for a station board but a line board occupies that slot in the original DXP, select the No
Board response.
When the prompt asks for a line board but a station board occupies that slot in the original DXP, select the No
Board response.
When you finish listing the board configuration, OK your selections.
(c) The VMMI program presents a screen graphic that depicts the boards installed in a default arrangement in the
main and expansion cabinets of a DXP Plus system. The default arrangement places station boards in
ascending slot order beginning with slot 1 in the main cabinet; it places line boards in descending slot order
beginning with slot 30 in the lower expansion cabinet. The VMMI program leaves a blank slot for any place
that you answered a station or line board prompt with a no board response 
						

							GCA40-182Understanding the VMMI(d) Since your system may not include one or both expansion cabinets or you do not care for the software
arranged board layout, use your mouse to move the board images to the slots that you would rather that they
occupy. Make a record of these board locations so that you or your installer can physically install the boards
to match your plan.
