Re: [time-nuts] Z38xx rack mounts
Hi Mike, Many thanks for the information, but as I understood it the question was asked with regards to the Z38xx Telecom styled units and not those variants such as the HP58503 series that were indeed built into HP desktop cases as you describe. The HP Z3801A etc and similar units from other manufacturers, Trimble for example, meet the Nortel GPSR specification, a copy of which is available for download at Didier's web site, and do not have the physical frame structure that would accept the HP link lock kit. However, the box itself of the Z3801A unit, although in this case just a bare aluminium enclosure, is very similar in size to the body of HP's normal half rack test gear, it's really the front panel on the Z3801A that flings a spanner into the works, so for anyone prepared to remove or modify that panel the rack mounting problem becomes much less of an issue. On the question of similarities in size between the Z3801A chassis and a standard HP 1/2 rack unit, there seems to have been a number of 58503A desktop units offered for sale, generally from China but not always, that the supplier claims to have been upgraded from a Z3801A, or sometimes a Z3805A. These units do have the rubber bumpers fitted, and what looks like an HP desktop style panel, but generally seem to retain the usual Z3801A aluminium enclosure so I imagine the bumpers would just be a push fit over that. One current Ebay offering clearly shows the internals as looking very much like a standard Z3801A but makes the claim Z3801A has been upgraded by us, which the feature is the same as 58503A. A screenshot of SatStat also shows the unit identifying as 58503A but aside from the cosmetics I've never seen any clear indication of what's actually claimed for this upgrade. Are there any significant performance differences between a Z3801A and a 58503A, and was any actual HP or Symmetricom firmware ever available to make such an upgrade, or is this more likely to be purely a cosmetic exercise with someone hacking the standard Z3801A software so it now identifies as a 58503A, or perhaps something somewhere in between?

Re: [time-nuts] Z38xx rack mounts
Yes many telco racks of old were 24 and as I recall nasa or someone had 28. That said I did what Bruce suggest some 8-10 years ago. Al panel spray painted to math the 3801 and cut a hole to fit the unit. Not having clever tools lots of drill holes a hack saw and then cleanup with a file. Came out well. I mounted the 2 in series power supplies to get to 36V in the remaining space on the panel along with on off switch fuse and light.

Re: [time-nuts] Z38xx rack mounts
Dave, I, too, hate piles of dumb little boxes. So when the Z3801 appeared I went on line, bought some sheet aluminum of appropriate thickness, cut a panel sized piece, drilled a few holes with an appropriate twist drill to allow the start of a hacksaw and then finished the clearance hole for the 3801 with a file. I supported the 3801 with some aluminum extrusion angle stock and then painted the whole she-bang with paint to match my stuff. And lo, no dumb little box, and it fits a standard 19 inch rack perfectly. If you send me an email address I will send a photo.

Re: [time-nuts] Z38xx rack mounts
Plan B and a half. or C and three quarters or whatever:-) I just measured a Z3801A case, can't speak for any others in the series, and that measures 9 1/4 inches from one outside edge of the front panel to the opposite side of the box itself. Cutting off opposing edges from two front panels, either to 9 1/2 inches each or perhaps a bit less to allow for a central dividing trim, would allow two units to be mounted side by side in a 19 inch rack with panels butted up but a bit of separation between the boxes, whilst keeping the existing fixings on the two outer edges.

Re: [time-nuts] Z38xx rack mounts
It's actually not a problem, as I mentioned before the boxes themselves are only 8 inches wide and centered in the panel. If you cut each panel down to 9 1/2 inches that would leave a separation between the boxes themselves of 1/2 inch so overall width behind the panel would be 16 1/2 inches, which is quite a common size for rack mount units anyway.
