Cat 5 Cabling Mnemonic-a few....

( I figured I'da Swipe this cause it's offten so easy to forget the B cabling order. )


Cat 5 Cabling Mnemonic

| No TrackBacks
I don't have to make Ethernet cables or punchdowns very often -- perhaps once a month, at most.  Something that has always bugged me is that every time I made a cable, I had to look up the T568A or T568B wiring standard to remember the termination order.

I remembered the basics.  Unpowered cat 5 uses pins 1 and 2 for transmit, and pins 3 and 6 for receive.  I knew that (white/)blue and (white/)brown never changed their pin numbers. A straight cable is always "A" to "A", or "B" to "B", while a crossover is always "A" to "B".

But for whatever reason, I could never remember the exact color order for the wires, and certainly could never remember which colors are swapped between T568A and T568B.

So I made a mnemonic.  There are a few cat 5 mnemonics on the web, but they mostly seemed like rote memorization rather than utilizing the power of a true mnemonic: a mnemonic is catchy.

So here it is:

"A" is for "apples", that always start green.
"B" is for "bees", that like tangerines.
Whites always come first, except is it's blue.
Brown always comes last, the color of poo.

This works (for me, anyway), but it requires some fundamental understanding of the wiring standard, and how Ethernet uses it.  I think this is fine, since if you don't understand the fundamentals, you shouldn't be terminating cable in the first place.
Blue - The Sky is Blue
Orange - the Sun is orange on the horizon
Green - on the Horizon there is trees
Brown - The Trees are in Dirt.

shrug.. seems to work - that's for A though.. B you just flip orange and green.

and my favorite:

I like that one because it has 2 of the colors in the saying and its funny and easy to remember!!

New jobs on the table hopefully not call center types of helpdesk....

Help Desk



as Being mainly the only offering with almost a Masters Degree , theirs mainly Call Center work.

however the non Glued to the phone positions with Desk-side support I can Hang with 

the Last Call Center Was getting me Kinda Dreary trapped behind a desk , After 13 years in IT , I'm more to the point I like face to Face interaction , Mixed duties and I'm far better than just entry level work on offer but have to often try to re-stomach it 

So Since I have experiance On my own time I'm doing consulting work to make up for the bleak IT outlook that is In Indianapolis , IN as the recession squeezes harder. 

For Seimans , they call it helpdesk , its really more of an entry level Active directory Administration job along with ticketing etc ,  perhaps some deskside support and trouble calls. 

or with the City of Indianapolis , In for actual feild work , 

or an offer from the Indiana BMV , for feild work as well ,

Contracts up for grabs makes me antsy , however I look forward to getting a few side contracts of my own.

Lampooning helpdesk jobs , I'll take them if I have too , I just can'a stand them with a phone glued to my head and 5 calls per second , I'd rather work desk-side support really 

I can fix the problem myself , instead of just ticketing and letting it fester.

 is finally migrated over to Google Apps , however little time to rest on my Laurels as much house keeping and
 Improvements are  is still needed. 


It is a Vast improvement to things and will hopefully help me Capture a better Client  base 
by Fixing up my Personal website , linked to my Small Business site. 


Particularly 


but the only thing of annoyance with Google apps Free , as my personal Site space only needs a few things is 
Lack of Picasa-web which is useful for site images and or common image sharing and make making adds easier and 


Blogger custom domains  with a Sub-domain option ie blog then "My-Domain" .com , net etc. 


wish list would Include adding Blogger to Free as well as Picasa as uploading images logs and etc via picasa tool is 
painless , and often very much faster , however as for my site or picasa web I have doubts of using terribly much space , just a few pica
and other things to help Evangelize my Websites or logos and typical images on a website or logos etc.
