WYTRON DVD-393 issues

An older DVD duplicator had some serious issues, The firmware needed an update, some writers needed to be rolled out, a hard disk to be installed, and a bunch of other stuff

It took me ages to get the firmware, and ages more to learn how to install it.

1- Get this CD ISO file, burn it in closed session and finalized disk.

2- Unattach all drives but the reader… if you are sure the writers are properly attached, Just put the CD in the reader

3- Press Mode for 4-5 seconds, then click MODE a few more times to get to update

4- Click GO until it tells you to restart

Now i have a WD800BB HDD i want to have there, i connected it to the second spot on the IDE cable connected to the reader (The one comming from the back of the unit), Now to where do the 7 writers go ?

Over the years, i have had pleanty of trouble with 8 port switches, With plenty of traffic going through such switches while analyzing database data on multiple computers, i have always had problems with them overheating and then the process halts, and it is easier to do it all over again than to rewrite the software and teach it how to resume, the answers have always been simple, Get an aluminum (Or if you are lucky to find a brass (zinc and copper)) heat sink, you would simply get some thermal epoxy, unmount the existing heat sink and fix your larger heatsink on the heating processor (the switche’s processor) and voila, problem gone.

Yesterday i got a D-Link DGS-1008D 8 port, Thinking that D-Link would actually put a decent heatsink on a switch, i plugged it in… then not very surprised, the thing overheated (And it is not even summer yet).

No problem, found a nice piece of aluminum from a hard disk enclosure, Cut it to an appropriate size, bent it a couple of times, and unscrewed the switch casing, Surprise, no heat sink at all (Surely this should mean they did not expect the processor to heat up so much), so i got my beloved thermal epoxy and fixed my new heat sink on the relativly large processor (As big as the die from an intel dual core processor), reassembled the casing, and put it back on the network.

A few hours later i went to see what it was doing, there was no network load, NONE, and to my surprise, the casing was very warm VERY, i unscrewed the case and the new heat sink is so hot it is annoying to keep your thumb on it (Thumb feels least).

So whats the story D-Link, am i missing something ? I got my handly little battery operated drill, and punched some holes above the heatsink, but the damn thing back on the network, i will go and check on it now (5 Hours later)…

The thing is very hot, i took off my heatsink and went to get a proper one, i though this was an overkill for something D-Link did not bother cooling !

Anyway, i will come back and finish this post, along with pictures of everything as soon as i find the time to install a new heatsink.
