Remote Power Control
Ø Some vendors allow full network
access, besides serial access.
² Telnet access (some even allow http!)
² Some UPS vendors allow SNMP
control with add-in modules.
Ø Restricting access to consoles
controls who cycles the power.
Ø Some vendors add serial ports to
power controllers.
Many UPS vendors allow SNMP management of their larger units. This often
includes the ability to shut down output circuits. (However, that’s not often
practical, since many machines are usually on each circuit.)
American Power Conversion Corp. (http://www.apcc.com/) make a series of
remote power control devices that let you cycle power on individual outlets.
These units also let you set up a cascaded startup sequence, to avoid power
surges when power on the mains return. These devices include a 10-base-t
interface, with telnet and http listeners as a standard feature.

The BayTechDCD folks offer a line of intelligent power controllers in many
different configurations. Some of their products even include modems for dial-
up access, as well as serial port control. (http://www.baytechdcd.com/)
Server Technologies also has some remote power control devices. Some
include a serial switch, so that you can switch your session to one of the
attached devices. These also include the feature that you can examine an
approximate power consumption for each of the switched outlets via remote
control! (http://www.servertech.com/products/Default.htm)
