Talk:19-inch rack/Archive 2

Screw holes and panel size
I felt the language needed to be modified somewhat. The article said screw hole mounting is no longer typical. I can only speak from experience on this, but I've almost never actually run into any other type of mounting. My main experience on this has been government and military (15 years), though even when I was in the civilian sector (8 years) screw holes were more common. Certainly the racks I've been building for aviation equipment the past couple months have been 72" tall screw mount types. :) In any case, I was also noticing there are no references to "A" panels.  The "one unit pizza box" has been described to me as an "A" panel space (two units would be a "B" panel, three a "C", etc.)  I don't know, however, if this a colloquialism or not.  Does anyone have any other references to this? Murasaki66 (talk) 15:47, 12 March 2008 (UTC)
 * I've never heard of this, and EIA-310 defines "A", "B", and "C" -type cabinets, with varying restrictions on height and depth, and whether protrusions (handles, etc.) are accounted for in the dimensions. I think your usage was indeed a colloquialism. jhawkinson (talk) 01:08, 2 June 2009 (UTC)

What is 2s?
Can someone enlighten us as to the definition of a 2s rack? Thanks! googhie (talk) 03:50, 22 July 2008 (UTC)googhie


 * "2s" probably means "2U", that is, two spaces or two rack units. That would be 2 × 44.45 mm (1.75 in) = 88.9 mm (3.5 in) tall, 19 inches wide (of course) and an unspecified length deep. A friend of mine runs a rack equipment store; here are some photos of a 2-space, 10-inch deep portable rack suitable for protecting rack equipment on the road: Audiopile - Cases- 2U rack with lids Binksternet (talk) 04:44, 22 July 2008 (UTC)

Mounting strips + Rails (Slides) illustration needed
In the 19-inch_rack section an illustration of the mounting strips would be really useful. Preferebly with measurements. Same goes for the 19-inch_rack section, which could also use and illustration or photograph. Electron9 (talk) 08:25, 3 January 2009 (UTC)

Merge with Pizza_box_form_factor?

 * No - the original pizza box systems have nothing to do with 19-inch racks.--NapoliRoma (talk) 05:28, 20 February 2009 (UTC)
 * Yes - they are used synonym -193.171.252.134 (talk) 11:20, 25 February 2009 (UTC)
 * A 19-inch rack is a rack, 19 inches in interior width, used to hold electronic devices in equipment rooms and laboratories.
 * A pizza box is a flat, square desktop computer.
 * I would assert that these are not synonymous.--NapoliRoma (talk) 02:03, 26 February 2009 (UTC)


 * No - The original Sun 'Pizza Box' was 16-inches square. Standard rackmount equipment is 17-inchs (give or take) wide.  While you may be able to rack mount a Sun 'Pizza Box' with appropriate adapter brackets or a shelf, so too can you rack mount a desk top computer.--Chassisplans (talk) 15:44, 7 March 2009 (UTC)

23" holes
This article states 23" racks have "holes on 1-inch (25 mm) centers". 23-inch rack states "Hole spacing is the same as for 19-inch (480 mm) racks".  Which is it?  --Pascal666 09:31, 3 April 2009 (UTC)
