My question is off-topic, but I know that some of the subscribers of this list administer server rooms, so it may be a good idea to ask it here. And it's interesting...
Do you know these computers with 2 power outlets? So you can plug them to 2 different power sources, and when one dies, the computer continues to get its power from the second, without powering off. Or when you want to replace its UPS, you just plug it off from the UPS and plug to the new UPS, without powering down the computer (because it continues to get its power on its second power outlet). Or when you want to move it from one cabinet to another cabinet, you just plug it to a lloonngg cable, then plug off the second cable, then move it to the new cabinet (without plugging it off), and then plug its empty power outlet to a normal cable connected to the new cabinet. So I'm looking for the same solution, but as a power outlet. Or RAV-SHEKA (I have no idea how to say it in English). Something with TWO power sources instead of ONE. So you enjoy all the benefits that I listed, not for one device, but for every device that is connected to this PASS-SHEKAIM (and don't confuse with UPSs that connected to two sources, because they don't allow you to replace UPSs without powering down the devices). I know that it's not as simple as it looks, and that the sources are not synchronized. But it's possible, and even must be simpler than UPS, so I'm sure there are such products. And if it's so difficult, maybe a manual switch can help too (i.e. it is connected to TWO sources, but gets its power only from ONE, based on A-B switch, so when you switch from A to B it is done continuously, without stopping for even a second. Of course, it's not really manual, because something must synchronize the sources during the switching). -- Eli Marmor [EMAIL PROTECTED] Netmask (El-Mar) Internet Technologies Ltd. __________________________________________________________ Tel.: +972-9-766-1020 8 Yad-Harutzim St. Fax.: +972-9-766-1314 P.O.B. 7004 Mobile: +972-50-5237338 Kfar-Saba 44641, Israel ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
