Patch Panel Manufacturers

As part of the How to Specify an Equipment Rack, a new page was added that covers Patch Panel Installation. Both topics are linked off the main page relating to Equipment Chassis Design. A few other pages in the section were also updated at the same time.

The patch panel page provides a description and a small list of manufacturers and should enhance both sections on chassis and rack design. A link to the patch panel page is also provided on the Engineering Dictionary page.

Interest in the PCI Bus is Falling

I was just updating some of the data relating to the PCI Bus yesterday, really just adding some data. There was no new page added.

The main page relating to the Peripheral Component Interface is the PCI Bus Description. Just a few lines of text were added, the real update occurred on the page containing the PCI pin out,[which does not have a page rank?]. I started to add a better description of the signals, and added a few more notes. There are also two additional pages that were updated, each related to PCI card size; Half Sized PCI Board, and Full Sized PCI Board. I guess the only other page is Manufacturers of PCI Boards, but it wasn't updated.

I noted a steep decline in page visits for any of the pages relating to the PCI Interface, by about 4-to-1 over the last three years. Google had data that goes back to 2004, so I posted their graph for PCI Bus searches instead.
The Graph is a Google Trend for the search term PCI Bus.

Electronic Equipment Cabinet Installation

Following the last posting covering Equipment Rack Design, a new page has been added to the same section relating to Chassis Installation within an Equipment Rack. The new page follows the topic on Equipment Cabinet Grounding and proceeds the topic covering Manufacturers of Electronic Racks [which leaves the section].

Over the last three years there has been no real increase in pages views for this section. In fact other then the page visits being some what flat, they have really been a bit low this year. The main page to the topic starts at; How to Design an Equipment Chassis, with some topics covering what to avoid too.

Remember if your designing a chassis for ship board use consider Components to Help with Anti-Vibration, or Chassis Self Leveling Products. Of course any of the other topics are relevant also; in addition to the one relating to Military Chassis Specifications.
