Unexplained intermittent CAN / 2CAN Jaguar problems at GSR

Source Please? I'm looking here:

<R59> If CAN-bus communications are used, the CAN-bus must be connected to the cRIO-FRC through either the Ethernet network connected to Port 1, Port 2, or the DB-9 RS-232 port connection.

And

<R50> Connections to the cRIO-FRC Ethernet ports must be compliant with the following parameters:
A. The DAP-1522 radio is connected to the cRIO-FRC Ethernet port 1 (either directly or via a CAT5 Ethernet pigtail).
B. Ethernet-connected COTS devices or custom circuits may connect to either cRIO-FRC Ethernet port; however, these devices may not transmit or receive UDP packets using ports 1100-1200 except for ports 1130 and 1140.

That seems to be two conflicting rules, but the 2CAN would probably count as a "pigtail"

Also, the 2CAN must be connected to the PD board by a dedicated 20 A breaker, ie not on the end part.

<R39> F. Custom circuits and sensors powered via the cRIO-FRC or the Digital Sidecar are protected by the breaker on the circuit(s) supplying those devices. Power feeds to all other custom circuits must be protected with a dedicated 20-amp circuit breaker on the PD Board.

Hooray for rules quotations. I am confused about in rule <R59> they say the radio may be connected directly OR with a pigtail. Them female to female connections, eh?

(Yeah, yeah I know, a pigtail is a male-female...)
