Understanding and Using the DLC170AD
Figure 7. DLC170AD Configuration Switch SW6
Note:
When using the DLC170AD with the DLC170DA, set the peak audio level rotary switches on
both function modules to the same setting to achieve unity gain.
The rotary switch is calibrated with the input terminated in 600 Ohms. Table 5 describes the rotary switch SW6
configuration options.

Installing the DLC170 Modules and SFP
The DLC170 and associated SFP are hot swappable, enabling you to safely install them while power is applied
to the host chassis. Use the information that this section contains to install either a DLC170AD or a DLC170DA
module. Before you install either module type, see the DLC170 data sheet for a detailed description of the
product specifications including environmental requirements that you must adhere to when installing the
modules.
To install a DLC170 in the host chassis (see
Figure 8) , perform the following steps:
1. From the back of the chassis, remove the two screws that secure the blank tray to one of the unused
function module slots (if necessary). Use any available function module slot.
2. Slide the DLC170 into the slot using the printed circuit board guide rails located on both sides of the slot.
3. Push the DLC170 in until it is firmly seated into the backplane and flush with the chassis.
4. Tighten the two mounting screws that secure the module to the chassis.
Note: Failure to properly secure the DLC170 to the chassis with the two mounting screws can
result in disconnecting the module from the backplane when you attach a cable to the
monitor jack located on the front panel.
