QUICK START GUIDE 2

Chapter 1: Introduction

The Server Technology Inc. Sentry family of products provides easy, practical, and secure solutions for
power distribution, power management and load-measurement for remote internetworking equipment
and branch AC circuits.

The Sentry Power Distribution Unit (PTPD) provides simple power distribution with cumulative load
monitoring for environments without a requirement for remote power management.

Features and Benefits

Sentry Power Distribution Units are available in 8-outlet, 16-outlet and 18-outlet configurations for
100-120VAC or 208-240VAC up to 30A. See Standard Models in Appendix C: Technical
Specifications.

Power Distribution

A Sentry Power Distribution Unit distributes a maximum of 30A AC power (dependant on PTPD
model) across a maximum of sixteen attached devices.

Load Measurement

The Sentry Power Distribution Unit’s load measurement feature eliminates guesswork by supplying the
cumulative operating load in amperes. This allows on-site technicians to maximize the equipment
installed and operated on a circuit without worry. Use of the circuit is maximized, while effectively
allowing a 10% to 20% safety margin. Remote users also may access this information at any time from
the Control Screen interface (Remote access not available on PTPD-xE models).

Over-Threshold Notification

Sentry Power Distribution Units features two standard over-threshold alarms; an audible alarm for the
local technician and a contact-closure alarm circuit which allows over-threshold alerts to be sent a third
party device (Not available on PTPD-xE models).

Technical Support

Server Technology understands that there are often questions when installing and/or using a new
product. Free Technical Support is provided from 8:30 AM to 5:00 PM, Monday-Friday, Pacific Time.
