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. Evan

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.
Chris 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.

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 -Shawn

We use both Tripplite and APC products with the network interface card (Web/SNMP). For out-of-band management, it seems likely that you could do something with the serial port and a modem but I haven't personally implemented that strategy. Regards, paul Paul M.
