Preparing and Installing the 9A426-02 Module
2-4
SRAM SIMMs
Each front panel port on the 9A426-02 Module is equipped with two megabytes of
Static Random Access Memory(SRAM).
To increase the SRAM of a front panel port, install the SRAM SIMM from the ATM
Memory Upgrade Kit (ATM-MEM-UGK) in the port’s corresponding SIMM
socket. To increase the SRAM of the module’s second front panel port, install an
additional SRAM SIMM in the port’s corresponding SIMM socket.
The SRAM SIMMs fit into the SIMM sockets located at the front section of the
module as shown in Figure 2-2. Installation instructions are included in the
upgrade kit.
APIMs
The preparation of the 9A426-02 Module includes the installation of at least one
ATM Port Interface Module (APIM) in one of the module’s front panel ports (if
desired, you can install two APIMs). The module is shipped with no installed
APIMs. You customize the module to your particular need by selecting from a
variety of APIMs, and then installing the selected APIM(s) in the module.
Figure 2-2 shows two APIMs installed in a 9A426-02 Module. Installation
instructions are provided in the following section.
Installing an APIM in the 9A426-02 Module
To install an APIM in the 9A426-02 Module, you must:
• Unpack the APIM
• Remove the 9A426-02 Module’s ATM-Port Retaining Plate
• Insert the APIM in the 9A426-02 Module
• Attach the 9A426-02 Module’s ATM-Port Retaining Plate
Throughout each of these procedures you must never expose the module’s
components to Electrostatic Discharge. Make sure you have attached the
module’s disposable grounding strap to your wrist and always place the module
on a non-conductive surface.
