>>Michel, there are a couple of companies that make an integrated phone line DSP switch and power strip or UPS; you dial the number that the power strip's modem is attached to, send it a set of DTMF (touch tone) codes that you've pre-programmed, and it initiates a power down/powerup sequence. You need to have a PC power supply that will immediately go to an on state on restoration of power; you may need to change the power supply from using a soft switch (momentary contact) to an ordinary rocker switch. Try
www.blackbox.com for a source, also, PC Power and Cooling; neither is a cheap source, but they're likely to have what you're looking for.

>Thanks, that's good to know. I'm not sure however I can support that infrastructure. We will keep looking. I'll keep you up to date with our improvments.
If your motherboards support Wake On LAN, there are SNMP-manageable systems available, too; SuperMicro and Tyan both made some mothernboards with SNMP-management features built in, for large $ amounts; I know that both Compaq and HP have made SNMP reset-able servers in the past, but that's a much heavier chunk of change than a new power supply. Obviously, these situations involve investing in an SNMP infrastructure throughout the environment. I believe that APC also makes SNMP-managed UPS systems, but it's been a long time since I read anything about them or their cost; I know at Weratherhill we decided to go with a dial-up controlled server reset based on instant-on power supplies and one of the enterprise-level APC SmartUPS systems (we used one of their M-series 2KVA UPSes with an external modem controlled reboot, and PCP&C instant-on power supplies for the servers.)
