NetBox version

v3.5.4

Feature type

Data model extension

Proposed functionality

Add Molex Micro-Fit 2x2 to power port inlet type.

Use case

Various devices utilize various Molex connectors for power input. For example, Cradlepoint E300 and IBR900-1200M routers and the Cisco 891 router all use a 2x2 Molex Micro-Fit connector.

Database changes

None required.

External dependencies

None.

Are these devices connecting directly to a power source via these connectors? Typically Molex connectors are used to connect an external power supply, which itself houses the device's actual power port.

They are external PSU. I have used 881's (similar to the 891's) before, it is a stupid connector.

However, if someone wanted to get pedantic they could model the power adapter as a separate device.

The Cradlepoints specifically can be hardwired to a vehicle ; the cable in this case just carries direct power and a couple GPIO lines.

Going to make this available for implementation as it does appear to be able to support direct connection to a DC power source.

Should likely add additional types for other devices (for example, Nexus 9k is typically a Molex Mini-FIT)

Can this feature be reviewed again for implementation, looks like there is already a solution under #13014

The use case I have is although typically you are right these devices will use an included external power supply to convert from 240vAC -> 48vDC, there is also a use case i have in certain environments such as industrial controls cabinets where they will be connected directly to a 48v power source, using the Molex headers. Not a showstopper but it would be good to model the connector accurately if only for my own sanity, rather than just using the "other" connector type 😄

Unfortunately no one has volunteered for this. The linked PR was closed as this issue needed to be re-evaluated.

We would need a new PR going forward

I'd be happy to work on a new PR to implement this, if implementing the new connector types is the way forward
