Introduction
ank you for purchasing the Tahoe 8216/8116. e Tahoe Remote Power Management System in-
creases the availability of your network infrastructure by monitoring and managing the power sup-
plied to your equipment. You can switch selected outlets on and oremotely using a web-based, tel-
net or encrypted SSH connection. Moreover, the connected devices may be rebooted automatically
in case of non-responsiveness. Each power outlet may be assigned to a separate user, which is useful
in the case of dedicated hosting services where each server is assigned to a dierent customer.
Optional GSM access (with Tahoe 8216/GSM only) allows power control even in situations where
the whole network is inaccessible.
We did our best to ensure the highest standards of reliability and performance of our products.
Having devoted many years of research and development, we are proud to provide a superior qual-
ity product unfolding new possibilities.
