Upgrading Circuit Cards
Installing a Circuit Card in the MAP/40
NOTE :
Read Chapter 4, “Running the Configuration Program,” of your MAP/40
Voice Processing Hardware Installation book and run the configuration
software program before installing any card, unless you are replacing a
card. You will need the output from the configuration program in order to
install your hardware. Your system arrived with output from this program in
the shipping carton.
Refer to this configuration data sheet in order to check addresses of exist-
ing cards. Also, when removing a card, set address switches and jumpers
of the new card matching to the old card.
Follow the steps below to install any circuit card. Get specifics for each card in fol-
lowing chapters.
1. Verify that the new or replacement card is on site and appears to be in
usable condition, that is, no obvious shipping damage, etc.
2. Refer to the output from the configuration program for this system to con-
firm that it is the correct type of card for that slot.
This is not necessary if you are replacing a card and not adding one.
3. If you are currently connected to the telephone network, notify the tele-
phone company that you are disconnecting. They will ask you which
extensions are affected.
!
WARNING :
If you disconnect the MAP/40 from the telephone network on a continuing
basis without letting the telephone company know, they can disconnect you
permanently (Digital Circuits ONLY).
4. Perform a “soft” shutdown of the system, if you have been operating the
MAP/40 as a fully loaded system.
Remove the configuration floppy diskette, if you have had the MAP/40 only
operating in order to run the configuration program.
5. Turn off the MAP/40 front panel main power switch and remove the incom-
ing AC power cord.
Also disconnect keyboard and video cords from the MAP/40.
6. Tag the power cord plugs with a note indicating that nobody other than
yourself should reconnect power to this equipment.
7. Remove the exterior chassis cover.
