Configuring the Dual DSU
!HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
The Model 7511 Dual DSU is designed to protect sensitive components
from damage due to electrostatic discharge (ESD) during normal
operation. When performing installation procedures, however, take
proper static control precautions to prevent damage to equipment. If
you are not sure of the proper static control precautions, contact your
nearest sales or service representative.
Procedure
To configure the Model 7511 Dual DSU:
1. Review Table 2-1 to determine the proper settings for your environment.
The first choice for each option (shown in boldface type) is the factory
default setting. If you choose the factory default value, you do not need to
change the position of the associated switch.
The factory default setting for all switches is Off.
2. Mark any options in the table that you wish to differ from the factory default.
3. Using Figure 2-1 and Table 2-1, verify that the switch settings for both DSUs
on the 7511 card match your selections.
Do not modify the settings of switches not listed in the table. Any switch
not designated for customer use should be in the Off position.
4. Where required, verify that the local and remote DSUs employ the same
options. For example, both the local and remote DSU must use the same
Line Rate and 64CC Data Scrambler settings.
