Killin Modems

For those who enjoy the more geeky side of my job:

Today the temperature in our server room began to climb, our air conditioner is dying and although we've had one on order for 6 months, it hasn't come yet. Well because of this situation we decided to start powering off non-essential servers. For the past 2 years we've been migrating dialup users to dsl users. So the quick decision was made to power off our Dialup users to save the heat, and convert the 24 modems to 8 since we seem to still have modem users.

Mind you this is completely impromptu, no planning at all.
problem 1 - the modem card inside the old Dell desktop running w2k3 server is disabled because it is incompatible with the external modem/serial bank.

problem 2 - after enabling all the OLD modems we go to patch the phone lines and find that the cable terminated are the wrong type of cable.... we need an Rj4 cable on one end and an rj11 on the other. Where are they? So I began to bring up the server hardware while the others scoured boxes for these OLD cables. Woops.

problem 3 - after they all searched for a few hours, I lucked out and found them within 15 minutes of looking, we patched them... all should work right? ... nay... no dial tone on the patch panel... SO we call the telephony guy over;

"sorry about this but we schedule a server maintenance that was supposed to be very very simple and in fact is turning very bad on us very quickly, could you drop everything and come help us?.. please?" he did, nice bloke that he is, and soon we discover that no dial tone means that the pairs weren't patched properly.

Mind you this entire project is reverting back to what we used 8 years ago, because since then they upgraded the modem capabilities.

We're now 10 minutes over our 2 hour window, and are manually repatching 8 telephone lines. Which means we're still not sure that our dialup server is functional.


THIS is exactly the kind of thing you want to do on a Friday. It's sort of the old nightmare project, the only thing is, there is very little stress because most of our customers are on DSL now.


Q: How many technicians does it take to revert a dial up server from 24 modems to 8 modems, thus reclaiming 6 rack units of space and about 1 degree of cooler room temp?

A: 4. One to start the project, one to run around asking questions and grab tools while the other guy scratches his head and says "remind me why we started this project again", one to know exactly how it all fit together 8 years ago, and one to patch the telephony jacks.

All that to say, it is working now. I blog this so that you know not all our projects go super smooth and professionally, but hey, we got it done. (-;
