The User Accessible Components on the motherboard of a 9A426-02 Module are

positioned in close proximity to one another. Therefore, to attain easier access for

removing a desired component, you may opt to remove an additional component.

For example, you may remove an SRAM SIMM to gain better access for

removing a Look-Up Engine.
