Modifying Your Vanguard 6435/6455
DIMs, SIMMs, DIMMs and Switches
Introduction The appropriate DIMs and SIMMs should have been installed on the motherboard at
the factory. If they are not, you can install the components.
This section explains how to:
• Add and remove DIMs.
• Setting DIM DIP Switches.
• Add and remove SIMM and DIMMs (SDRAM, FLASH, Data Compression,
Encryption).
• Set Switches.
For instructions for removing the motherboard, refer to the “Accessing the
Motherboard” section on page 3-16.
Adding or
Removing a DIM
Refer to Figure 3-10 for the location of the DIM Slots. Placement of the DIM
determines if the associated ports acts as a DTE or DCE (see Figure 3-11).
Figure 3-11 shows how to position a DIM on the Vanguard 6435/6455 motherboard
and set the DIM DIP switches. The Vanguard 6435/6455 supports V.11, V.24, V.35,
V.36, and DSU DIMs.
For instructions for removing the motherboard, refer to the “Accessing the
Motherboard” section on page 3-16.
Note
The DIM DIP switches are located under the DIMs. Therefore, before you can
reset the switches, you must remove the DIM.
