Does anyone have a copy of the EIA-310 document? (For the uninitiated, EIA
is the Electronic Industries Alliance, formerly the Electronic Industries
Association.)
EIA-310 carries the title," RACKS, PANELS AND ASSOCIATED EQUIPMENT."
According to a summary of this document in the EIA 1991 Catalog, it
incorporates metric measurements. However, every manufacturer of
rack-mountable equipment in this country specifies that their products fit
19" standard racks (or other less common sizes). The standard they refer to
is allegedly a RETMA one. However, RETMA became EIA 43 years ago, so I
always take a RETMA standard rack reference as an EIA-310 reference. (RETMA
stands for Radio Electronics Television Manufacturers Association.)
If anyone has a copy, could you please say whether it specifies 19" or 480
mm.
Also, a vertical module in a rack may be specified as being 1-3/4" deep.
Again, is this really 1.75" or is it 44 mm (or 45 mm)?
