Today ended up being a long day. My trusty little Cisco 2610XM router just died today. Leaving me for a while without access to the internet and my Exchange and Web Servers unable to talk to the outside world. At first I thought that the power supply just failed, and having a variety of cisco routers available from my cisco lab I tried switching the power supply out. It didn’t work however, and I found that the power supply of the Cisco 2610XM router worked just fine in a 2611 router. So I reseated all the memory and tried again, still nothing. Next I tried it without any memory, still nothing. Best I can figure now is that something went wrong on the system board. So I’ll be sending the unit back to get replaced.
In the mean time however I need the network to be up. My 2611 router doesn’t show my ADSL WIC so I can’t use it so I figured I would just configure the 2wire modem I received from AT&T to get everything up and running. It should be easy right? Wrong. This modem must be the most complicated piece of equipment on the planet from the way AT&T talks about it. No one there seems to know how to configure it with static IP routing. Hey, if you just want to give out dynamic IP addresses to your clients then that’s easy, however we had the hardest time getting the router to show my server in the device list on the router. It took 2 1/2 hours on the support line with AT&T and 9 different departments to solve the issue and get my static private address to point to a static public IP. Something that with my Cisco router could be accomplished with one command in the IOS and take no more than 30 seconds.
It’s all setup now and things are working. I decided to mount both my Cisco wireless router and Dlink gigabit switch to the wall behind the rack I have the server and switches on. This keeps them from having to be on top of the desk or rack and keeps everything out of the way. The AT&T router will now be my #3 backup, I plan on getting another Cisco router that will support my ADSL WIC and configuring them both. That way if for any reason my router dies again (I’m hoping not) I’ll be able to put the new one in and be down for only a short period of time. Downtime is not an option when you are hosting your own web sites and email servers.
