Modules have their own physical interfaces. See the documentation for the respective module for
more information.
•
The two Ethernet interfaces are used for 10/100 testing and for administrative functions on the unit,
such as upgrading firmware.
•
The 2.5 mm mic/headset jack and USB port are for future use.
1.3 General product handling and operation
This section provides basic information for general operation. For most functions and tests, the buttons,
display, and other components operate in a similar fashion. Once you become familiar with general
operation, you should be able to set up and run most functions and tests, referring to this document only
as necessary for specific technical details, contained elsewhere in this document.
1.3.1 Powering on/off and sleep mode
When the unit is off, the power button turns it on. When the unit is on, the power button prompts you
whether to power off the unit or to place it into sleep mode. Sleep mode allows the unit to save power but
return to active testing more quickly than a full boot up. To restore the unit from sleep mode, press the
power button once again. Note that the restoration process causes the unit to recheck module and
licensing status, after which it returns the screen to the default menu, not necessarily the menu that was
active when sleep mode was activated.
The unit supports automatic sleep mode activation after a specified amount of idle time. For more
information, see
1.3.2 Attaching, detaching, and handling modules
CAUTION:
Before attaching or detaching a module, the unit must be powered off or
placed into sleep mode. Failure to do this could result in damage to the module
or base unit firmware. For more information on initiating sleep mode, see
Powering on/off and sleep mode
NOTE:
To prevent damage to the module bay and to keep electrical connections clean, you should
keep the module placeholder (the “dummy” module) installed when no module is in use. New
units are shipped with the placeholder attached.
Modules are fastened to the base unit using fastener screws attached to the upper “feet” of the unit. To
remove a module, loosen/disengage the two screws and gently pull the module from its electrical
