[. . . ] 19" Rack-mount 12-Slot Standalone Media Converter Chassis User's Manual December 2003 TABLE OF CONTENTS Introduction . v i INTRODUCTION About This Guide Welcome Thank you for choosing the 19" Rack-mount 12-slot Standalone Media Converter Chassis. This device provides power and protection for media converters in one reliable package. Purpose This guide discusses how to setup and install your 19" Rack-mount 12-slot Standalone Media Converter Chassis. Terms/Usage In this guide, the term "Chassis" (first letter upper case) refers to your 19" Rack-mount 12-slot Standalone Media Converter Chassis, and "chassis" (first letter lower case) refers to other chassis. Features · · · · · · Supports two load sharing, hot swappable power supplies. Three high volume cooling fans ensure perfect operating environment. [. . . ] Its simplicity hides the fact that the Chassis employs a sophisticated power distribution system. All converters are supplied from the one hotswappable Power Supply. However, this is where their common connection stops. Each slot has its own protection system that isolates each converter from any problems that might occur with either the power supplies or another faulty converter. This offers the best possible protection to your investment in the various media converters. Fan Indicator LED's These should illuminate under normal operating conditions. Slot Power LED's These will illuminate when converters are loaded into the Chassis' slot. The LEDs will extinguish if converters are not installed or if there is a problem with the power supply. 15 COOLING The Chassis holds up to two power supplies and twelve media converters, so it needs to have reliable form of cooling. This Chassis has three fans located at the rear of the Chassis, and draws air into the Chassis. Each fan is connected to the Status Monitoring Panel on the front of the Chassis. Even with only one fan working, the Chassis is capable of operating under normal operating temperatures. For the purpose of cleaning, the Fan panel assembly can be removed for periodic maintenance. Switch both power supplies off, and remove the six securing screws. Disconnect the three power cables supplying DC to the fans. The fans can then be cleaned with a dry cloth. Replace the fan panel by reversing the above procedure. 17 TECHNICAL SPECIFICATIONS Chassis Specs Capacity: 12 slots ­ up to 12 converters Chassis: Aluminium, Steel Power: Up to two load sharing, hot swappable power supplies LEDs: 3 Red for fan status, 12 Green for slot power status, 1 Red for each power supply.
