Step-4 : Install C-Size Modules
C-Size Modules can be installed in any slot except slot 0, and need not be
installed in adjacent slots. However, when installing multiple modules
which make a virtual instrument, the modules should be installed in
adjacent slots. This allows cables to be easily connected between the
modules. When installing a virtual instrument such as a scanning
multimeter, install the multimeter to the left of the multiplexers, which are
then installed in adjacent slots to the right.
Use Figure 4-4 or 4-5 and the the following steps to install C-Size modules:
1. If the mainframe is turned on, turn the mainframe off by
pressing the button in the lower left corner of the mainframe.
2. Insert the module into the mainframe by aligning the top and
bottom of the module with the card guides inside the mainframe.
Slowly push the module straight into the slot until it seats in the
backplane connectors. The front panel of the module should be
even with the front edges of the mainframe.
When installing the module in the Agilent E1421 mainframe, the
"top" of the module will be on the left when it is installed
horizontally.
3. Tighten the retaining screws on the top and bottom of the module.
NOTE If the module fails to insert properly, make sure you are lined up in the card
guides and make sure the tabs are turned towards the center of the card.
