Hardware Installation
Memotec Inc. 4-5
You can increase the number of voice channels supported by upgrading the DSP module.
Refer to “DSP Modules” on page 5-11 for a description of the different kinds of DSP
modules that can be installed.
CAUTION:
These DSP modules are for the SDM-9210/9210GW, SDM-9220/
9220GW, SDM-9230/9230GW, SDM-9606 or SDM-9620 only. DO NOT use
a DSP module intended for the SDM-9360, SDM-9380 or SDM-9585.
NOTE:
The SDM-9606 has one DSP socket for a single DSP module (see Figure 4-
2 ).
4.3.2 Installation Procedure
NOTE:
To ensure proper digital voice operations and GSM traffic handling, install all
required DSP modules before you power up and configure the unit.
To install a DSP module:
1. Wear an ESD (Electrostatic Sensitive Devices) wrist strap, and attach it to one of the
ground lugs on the SDM-9600 chassis:
• Front ground lug, located beneath the
POWER ON
LED. Refer to Figure 5-1 .
• Rear ground lug, located to the right of the dual power input modules. Refer to
Figure 5-2 .
CAUTION:
Electrostatic charges can damage system components. Always use
an ESD wrist strap when accessing internal components of the unit.
In countries where a 2-pin non-grounded power cord must be used, ensure that the
SDM-9600 is independently grounded with a wire from Ground securely attached to
one of the ground lugs on the SDM-9600 chassis.
2. Locate the blade on which you want to install the DSP module. If this blade is already
installed in the SDM-9600 chassis, remove it as described in
“Removing a Blade” on
page 4-12 .
3. Place the blade on a hard, flat surface. Skip to step
6
if the DSP socket is empty.
4. If you are upgrading a DSP module that has already been installed:
