I'm in a situation where I'm going to have to deploy a rack of servers in an unmanned location in another country. On rare occasions, I've had systems that would not recover gracefully from a warm reboot and needed the power cycled. Years ago, I had such a device from APC, but haven't needed one in a long time since all my locations are staffed. I'd welcome any suggestions from the list.
Best regards,
Have a look at http://www.realvnc.com/products/KVM-over-IP/ which is one product which supports kvm (keyboard video mouse) over IP, the advantages are obviously the ability to power cycle etc a box just like if you were in front of it, or see error messages if the network connection is down.

I use these, you can hook up a modem to some of these so they can be rebooted without internet connectivity too:

depends on the server vendor, most have remote access cards such as DRACS or iLO etc. If Dells these also have a BMC which means you can powercycle the box without having to buy a DRAC although you can't 'see' whats going on on the console for that you need a DRAC.
If its just remote power cycle then Baytech do good options that are easily expandable although remember that you'll need to double up on sockets as the servers will have redundant PSU's wont they.

Baytech has an interesting line, including some modular units so you can build a 4-port serial + 4 switched power ports with ssh access.
Other vendors I'm aware of in this space: - APC still has a relevant product line and is the cheapest I have come across until the surplus DLI units another poster mentioned - server technology - cyclades

I've deployed the iBoot range of units from dataprobe in 2 of my DC's, and they pay for themselves in no time. Simple web interface, per user and per port settings, and barring the link *and* power going down, you can recover from most fatalies.

Ahhh, the APC MasterSwitch. I had a bunch of these at my last job. Some of the things people have already suggested look interesting though :)
APC still makes the MasterSwitch line too... http://apcc.com/products/family/index.cfm?id=70 and http://apcc.com/resource/include/techspec_index.cfm?base_sku=AP9225

certainly, if one has access to bottomless funding, one can't go wrong with those. :)
for those on a tighter budget, you might want to look at something like this:
