NetBox version

v2.11.1

Feature type

Change to existing functionality

Proposed functionality

  • Create a cable type "Power (Y type)"
  • When this cable type is used, allow multiple power ports to connect to the same outlet
  • Calculate power draw to that outlet to be the sum of both ports attached to the cable

Use case

It's occasionally necessary to use a Y adaptor to power both power supplies on a device when not enough outlets are available. Example of such a Y adaptor:

Currently there is no acceptable way to model this cable type within Netbox.

Implementing this will likely require overhauling the cable model completely. Which isn't to say we won't do it; just setting expectations. However, we may want to re-cast this as general support for multi-point cabling, as I suspect there's a high degree of overlap with modeling breakout cables (e.g. a 40GE interface connected to four channelized 10GE interfaces).

Great idea Jeremy to make it generic, there are a few other use cases where this pops up. Ex. Copper cabling for telephony that use these types of Y cables.
