RE: Worst design decisions?
* How about the plastic stand-offs that hold the AIM-VPN cards in the 2600 and 1700 series. Yeah...the ones that DON'T come with your SmartNet replacement chassis and that you have the pull the entire board to release. * And how about this: Cisco: PICK A BUSINESS END ON YOUR SMALL OFFICE ROUTING EQUIPMENT. Most of my less clued customer like to "help out" and rack the equipment ahead of time. And it always gets done pretty side out. Yeah..the side with a Cisco logo and three lights. It sure does look like it should be the front, but it's useless that way. Maybe putting the power on that side would clue people in to the fact that it's basically useless to point that at the easy-access side of the rack. * PCs with built in Ethernet that is so close to a lip on the case, with the release pointed down, that you need to use a screwdriver/knife/whatever to release the cable. * Lack of proper SPAN support on 29xx/35xx series switches. Read only? I can live with it. No inter-vlan? Very bad. Does that make my worse design decision using Cisco CPE at my small customer/remote office sites? Hmmmm.... Daryl G.

Grrrrr! : Thats to prevent it from being disconnected accidentally : (or for any other reason :->) Actually, the original intent of those hoods was to snagproof the locking tab -- which is of interest to places that have the Web O' Patch Panel Cables. Think "pull a disconnected cable out of the tangled mess and try not to break off the locking tab". 8-) So it's a tradeoff between preserving the RJ45 connector and making it easy to disconnect. -- -- Todd Vierling <tv@duh.org> <tv@pobox.com>
Actually, as awkward as those rubber hoods are, what I like about them is that when you're pulling a disconnected patch cable through a rat's nest of wires, they prevent the plastic tab from being bent backward. On Thu, 18 Sep 2003, John Palmer wrote:

Not a shameless plug since I don't work for them or own any stock, but Avaya makes a snagless cable with a second clip which hinges from the back of the RJ-45 connector. Makes them easier to use as opposed to hooded and regular vanilla cables. -- Nathan Norman - Incanus Networking mailto:nnorman@incanus.net Liberty may be endangered by the abuses of liberty as well as by the abuses of power. -- James Madison

Since you are the second person to point that out... 2 suggestions: - 1. Cut the head off and re-crimp it if it has to go that far. - 2. Use regular power tape, scotch tape, or duct tape to hold the tab down until it has reached its destination. (You do keep duct tape around right?) ;-) Gerald - How are ya? Never been better, ...

(You do keep duct tape around > right?) ;-) Best tape to use is masking tape it usually will not leave a heavy residue . Just do not leave tape on them in storage any opf the tapes will leave residue & the tangs take a memory . But I also liked another type of hood that did not use a complete surround covering over the tang . It was more of a thin spring tang same width as the rj45 tang & rising from the rear of the hood which went over the top of the rj45 tang & about half way down its length . But even it had some of the bad properties of the rj45 tang it could bend & then it caught on everything or just broke off . Tho it made the last slot near the bottom easier to contend with .

True but there are also snagless connectors available where the release tab actually makes a V shape such as to not catch when you're pulling it through a cable raceway. They definitely do cost a few more $$ though. I believe the usual suspects... Panduit, AMP sell them. Luke

Level3 gives customers cables with these ends. Very nice. Looks like a very odd (but quality) crimping process. Absolute genius. I just reworked a really messy cabinet and all the patch cables had those connectors. Not one snag. Best Connector Ever. C

I wouldn't consider that a design flaw. In fact, in some environments that may be the preferred way of doing it. Not only will it look nice and neat, but if the side of the box where all the connections are located on is less accessible to humans that may help lessen opportunity for someone to touch something they shouldn't be touching. Unless your devices are constantly being re-cabled, this might be considered good design practice. John
