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 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 Series

3700 is turned off and disconnected from line power.

• If the switching module is already connected to a device under test

(DUT), make sure power is removed from all external circuitry.

NOTE For inexperienced users, it is recommended that DUT and external circuitry not be

connected to switching modules. This will allow you to exercise safe close/open

operations without the dangers associated with live test circuits.

Module installation

WARNING Slot covers must be installed on unused slots to prevent personal contact

with high voltage circuits.

Perform the following steps to install a switching module into the Series 3700 mainframe:

1. Turn the Series 3700 off and disconnect the power line cord and any other cables

connected to the rear panel.

2. Position the Series 3700 so that you are facing the rear panel.

3. Remove the slot cover plate from the desired mainframe slot. Retain the plate and screws

for future use.

4. With the top cover of the switching module facing up, align the module's card edge into the

slot's card guide and slide in the module. For the last ¼ inch or so, press in firmly to mate

the module connector to the mainframe connector.

5. 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.

6. Reconnect the power line cable and any other cables to the rear panel.
