In summary, the Keysight N6709C is the rack mount kit required to install any N6700 family mainframe (N6700C, N6701C, N6702C) into a 19-inch equipment rack. It supplies the front rack ears and rear supports that replace the standard rack rails and slides, which are not compatible with the N6700 because of its 1U size and airflow requirements.
What is the N6709C used for?
It is the only supported way to rack-mount a Keysight N6700 mainframe. Standard rack-mount hardware will not work — the N6700 chassis is 1U with side-only airflow, and conventional rails block the vents and don't match the chassis mounting points.
The N6709C is required equipment any time an N6700C, N6701C, or N6702C is going into a rack. It does not change the system's electrical or measurement behavior; it is mechanical hardware only.
Why can't I use a generic 1U rack kit?
The N6700 vents air from the sides rather than the top or bottom. A generic 1U slide or rail set sits flush against the chassis sides and obstructs cooling. The N6709C is engineered to clear those vents and to land on the rear panel without interfering with the I/O ports used for cross-mainframe sequencing.
Industry standard 19-inch racks hold up to 42U or 48U; one N6709C kit secures one mainframe in 1U. A fully populated 24-bay rack of N6700 mainframes — each holding up to 4 channels — yields up to 96 independent programmable outputs in a single bay. The N6709C does not consume additional rack space beyond the 1U the mainframe itself occupies.
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: Standard rack-mount hardware will not work with the N6700. If the mainframe is going into a rack, the N6709C is not optional — order it explicitly. Trying to rack-mount the N6700 with conventional rails will obstruct the side air vents and may compromise cooling.
