User-Accessible Components on the Module’s Motherboard

The user accessible components on the module’s motherboard include two Look- Up Engines, up to two user-installed ATM Memory Upgrade SRAM SIMMs, and up to two user-installed ATM Port Interface Modules (APIMs). See Figure 2-2.

NOTE

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.
