Companies like this never do anything, much less anything of this magnitude without a massive army of consultants who put a meaning behind each and every pixel. This gets expensive, and the writing of checks with lots of zeros in them assures CxOs that they shelled out for something worthwile.
Since I was not informed of the meaning behind the logo, I will attempt to discern it for myself. We will start out with the washed out colors, a faded steel blue and a nondescript red. They mimic the pale skin tones of the pasty faced wiring closet trolls that so love Cisco equipment, a tip of the hat to you boys and girls.
The vertical lines are really feng shui based, but far from providing easy access for dragons to pass, it is actually landing lights for them. You don't think Cisco keeps it's marketshare through high prices alone do you, it needs large reptilian help.
Moving on, we get to the font, a classic early 80s mac piece meant to show the advanced nature of the Cisco UIs. If IOS can do that fancy graphical stuff, our fonts can too, the PARC boys would be so proud of this achievement, you can almost see them shrug with apathy over this moment.
Last up, we have the sheer blandness of it all, meant to promote the nigh boundless excitement of a closet full of boxes who's only purpose seems to be making LEDs blink and fans pushing hot air out the back. Be still my beating heart, Cisco seems to have hit a home run here. µ
