In summary, the Keysight N6708A is the filler panel kit required when an N6700 family mainframe is configured with fewer than four modules. Each kit contains three filler panels; each panel fills one empty module slot. Without filler panels in place, the mainframe will not airflow correctly and proper operation is not guaranteed.
What is the N6708A used for?
It closes off empty module slots in an N6700C, N6701C, or N6702C mainframe. The N6700 is a forced-air-cooled chassis with side vents; an open module slot disrupts the intended airflow path and can affect cooling on adjacent installed modules. The filler panels restore the airflow profile of a fully populated mainframe.
Why three panels per kit?
A four-slot mainframe configured with a single module needs three filler panels. Each kit is sized to fully outfit that worst-case configuration in one purchase. Customers running two-module or three-module configurations use what they need and keep the spares for future module additions.
Filler panels are mechanical only — there are no electrical connections, no firmware impact, and no calibration considerations. They are a required consumable any time a mainframe ships partially populated, which is common in build-to-order N6710C, N6711C, or N6712C systems and in mainframe + module orders placed under the standard ordering path.
Accessories Supplied
Each module is supplied with the quick-disconnect plugs needed to wire to the mainframe’s output and sense terminals. Relay and high-speed test extension features are factory-installed options (see below) and are not field-installable accessories.

Notes |
| Quick disconnect plugs (power & sense) |
Standard with the module. Enables fast system setup and maintenance. |
| Factory-installed options |
Output disconnect relays (Option 761) and output disconnect/polarity reversal relays (Option 760), where available, are configured at order time and built into the module. |
| Documentation |
Mainframe ships with documentation; modules install into the mainframe and inherit its host control and connectivity. |

Important: Filler panels are not optional. The N6700 mainframe relies on a defined airflow path that depends on every slot being closed — either by an installed module or by a filler panel. Operating the mainframe with open module slots is not supported by Keysight.
