Switching module installation and connections
In order to exercise close/open operations explained in this section, a switching module
(or pseudocard) must be installed in the mainframe. A switching module can be installed
by the user, however external connections to the switching module are only to be
performed by qualified service personnel.

WARNING
Perform the following steps to install a switching module into the Model 2701 mainframe:
1.
2.
3.
4.
5.

For inexperienced users, it is recommended that DUT and external circuitry not
be connected to switching modules. This will allow you to exercise close/open
operations without the dangers associated with live test circuits.
To prevent electric shock that could result in injury or death, NEVER
handle a switching module that has power applied to it:
•
Before installing (or removing) a switching module, make sure the
Model 2701 is turned off and disconnected from line power.
•
If the switching module is already connected to DUT, make sure
power is removed from all external circuitry.
Slot covers must be installed on unused slots to prevent personal contact
with high voltage circuits.
Turn the Model 2701 off and disconnect the power line cord and any other cable
connected to the rear panel.
Position the Model 2701 so you are facing the rear panel.
Remove the slot cover plate from the desired mainframe slot. Retain the plate and
screws for future use.
With the top cover of the switching module facing up, slide the module into an
empty slot. For the last half inch or so, press in firmly to mate the module
connector to the mainframe connector.
On each side of the module, there is a mounting screw. Tighten these two screws to
secure the module to the mainframe. Do not overtighten.
Reconnect the power line cable and any other cables to the rear panel.
When you turn on the Model 2701, the model number of the switching module will
be briefly displayed.
