Re: "Can you ship right length cables for the customers so everything is neat and tight"

Re: "Each time customer/vendor touches a cable behind the back for troubleshooting, it takes couple of hours to make sure system health is normal due to the cabling mess at the back"
This should also be resolved with the new cable trays that we have been shipping since mid-2015. Can you share more details if that is not the case?
