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 oremotely 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 dierent 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.
Tahoe 8216
e Tahoe 8216 is the main unit of the Tahoe Power Management System. It allows the user to man-
age its ten built-in power outlets and all chained Tahoe 8116 devices.
e Tahoe 8216 can be chained with several (up to 32) Tahoe 8116 extension units to provide ad-
ditional power outlets at lower cost. Input voltage, current and active power consumption of each
unit can be remotely monitored.
Tahoe 8216 Front Panel
LCD/keyboard
e LCD display shows the current state of the device and the build-in keyboard allows the user to
change the state of outlets and gives quick access to basic settings.

LAN
e Fast Ethernet interface is used to connect the Tahoe 8216 to the Local Area Network (LAN). It
may work at speeds of 10 Mbps (10Base-T) or 100 Mbps (100Base-Tx), in full-duplex or half-duplex
mode. e mode of transmission is selected automatically, although a specic setting can be set.
e device should be connected to an Ethernet switch or a hub using a straight patch-cord cable or
to a PC, a router or an uplink port in a switch using a crossed-over cable. Aer connecting the cable
the Link LED should light up.
Status LEDs
e following status LEDs are placed on the front panel:
LINK lit when the device is connected to a LAN
LAN Act LAN activity, blinks when data is sent or received
10/100M LAN connection throughput – lit when 100 Mbpsconnection speed is negotiated
GSM GSM status (o– GSM disabled, on – not registered to the network,blinking – reg-
istered to the network)
