Over the years, we have heard many data center personnel state that DHCP cannot and will not be used for infrastructure pieces like cabinet PDUs. All Server Technology CDUs are shipped with DHCP enabled so that the user can setup the DHCP server to provide IP settings based on MAC address. For those installations where that is not a viable solution, Server Technology has developed the StartUp Stick for quick mass-deployment. Now, instead of walking the floor with a crash-cart and writing scripts to handle the initial network configuration, you can sit in the comfort of your office using our simple spreadsheet configuration tool and then walk the floor with this simple tool instead.Read More
Question from Steven G.: How do I calculate the power usage for devices attached to one of your Smart PDU's by looking at the digital readouts on them? I understand the 3-phase power calculation of P=VA*1.73, but is that done on each leg/phase (x,y,z) for the PDU? An example from a CS-24VY-L30MA is X=4.6, Y=4.6, Z=6.3
On occasion, an installation consists of only a few cabinets and it is desirable to place individual UPS units within each cabinet. Although Server Tech does not provide UPS products and remains manufacturer agnostic, there are a couple things that should be considered from the power distribution point of view.
Question from Carlton <omitted>: I have multiple remote DSL modems that each stop working two to three times a week. I've deployed 2-outlet Sentry Switched CDU units to allow me to remotely reboot them when they hang, and they work great! But, I have to wait until someone notifies me of the problem, then I have to manually login to the CDU to initiate the reboot. I've noticed that the DSL modems fail to respond to ping requests when they hang. Is there a method available to automatically reboot the DSL modems when they stop responding to ping requests?
This is a common question I receive: How much power should I provision for my cabinets?

Question from Jay <omitted>: I am presently evaluating a CDU model #CS-27VY-L30M and have noticed that the power input cordage does not involve an oversized neutral conductor. All five conductors are 10-gauge AWG. Isn't an oversized neutral required to avoid the possibility of overheating the conductor?
