Re: Cable Colors
I don't know of any hard standard in use anywhere. I've generally taken to the following:
Green == low-bandwidth straigh-through Telephone, T1, Serial, etc. Purple == Roll Cables (almost always serial, sometimes telecom) (8-1 7-2 6-3 5-4 4-5 3-6 2-7 1-8) Orange(C) == EIA-568b cross-over cable (ethernet xover) Orange(F) == Multimode Fiber Yellow(F) == Singlemode Fiber White == Clear (inside VPN concentrator network) Black == Crypt (Outside VPN concentrator network) Blue == Publicly accessible networks Red == Backend (usually OOB management) networks Pink == KVM (KVM switch <-> Dongle)
Occasionally I encounter needs for greater specificity, but, these usually do most of what I need.
I'm sure others use entirely different choices.
