Installing Isa/Pci Cards - Siemens SIMATIC Panel PC 870 Equipment Manual

Caution
The electronic modules on the p.c. boards are very sensitive to electrostatic dis-
charge. You should therefore take appropriate precuations when handling them.
Please refer to the directive for electrostatically sensitive devices (ESD guideline
at the end of this Manual).
Installing the SDRAM modules
When plugging the modules, proceed as follows:
1. First open the device as described in Section 4.1.
2. Plug the modules into the socket. Please observe the recess (anti–rotation
element) on the connector side of the SDRAM module.
3. Push the module down, exerting slight pressure on it until the locking snaps into
place.
4. Close the device.
Caution
Risk of damage!
Make sure that the modules fit tight in the socket; otherwise, they can fall down or
be damaged.
Installation
The memory configuration is detected automatically. When the device is turned on,
the mapping of base memory and extended memory is displayed automatically.

Installing ISA/PCI cards

Notes about the cards
The computing unit is designed for the use of cards as per the AT/PCI
specification. The dimensions of the cards must not exceed the stated dimensions.
If the height is exceeded, contact problems, malfunctions and difficulties with
installation cannot be ruled out. The illustrations show full length AT/PCI cards.
Depending on the slot, there might be constraints concerning the overall length.
