1Introduction
1.1 Purpose
The purpose of this document is to define the functionality, operation, and maintenance of the
SR20-FDD Data Center. This document serves as the sole reference for the system
functionality at time of delivery. Any change to the Functional Specifications will require
agreement via the change control process between the user and ADDC. The SR20-FDD was
designed to provide long range (up to 24 km) remote operation via fiber optic cable KVM of up
to 20 BioDigitalPC®computers.
1.2 Scope
Summarize the purpose and contents of this guide and describe any security or privacy
considerations associated with its use.
This guide has 3 main sections, system functional specifications, operation, and maintenance.
The maintenance section requires that only qualified technicians gain access to the internal
components of the system. The system’s power management controls via the front panel touch
screen or the ROMWare GUI are PIN and password protected for security.
1.3 System Organization
Figure 1 is the block diagram for the SR20-FDD system. The system consists of the following
main components:
• SR10 Module
• AC-DC 12V Power Supply (main power source for SR10 Module and fans)
• DC-DC 12V-5V Converter (power for all KVM modules)
• ROMWARE Lite Module (provides remote power control of each individual PC Card)
• ROMWARE Lite Software (provides touch screen control and/or web GUI remote power
control)

2System Description
The SR20-FDD combines the power of two ADDC SR10 modules with the Made in the USA,
long distance, fiber KVM (Keyboard, Video, Mouse) terminal for extraordinary capability. The
SR10 module is specifically designed to be integrated into a SR20-FDD features 20 separate
and distinct computers with USB and video delivered through fiber KVM. Each computer is
connected to a high-speed layer 2 managed switch through 3 physical 1 GbE NICs. Each of the
two SR10 modules has an embedded switch that manages the individual NICs and has two 10G
SFP+ trunk ports. Serial and HTTP based switch management is included. Individual auto and
remote computer power control.
2.1 Key Features
The SR20-FDD System provides the following key features:
•20 Separate BioDigitalPC®Cards that can be easily remove and replaced for ease of
maintenance and upgradeability.
•Remote power control for each individual PC Card via a web GUI to allow remote
resetting of the PC Card.
•Each PC Card has its own KVM over fiber adapter to allow an additional remote
operation of the PC Card and its software applications.
2.2 System Inventory
The SR20-FDD system ships with the following components:
•SR20-FDD Chassis (Figure 2)
•1 each Cable Management Arm (Figure 3)
•4 each 10Gbps SFP+ Cables (Figure 4)
•2 each AC power Cord (Figure 5)
•2 each AC/DC Power Supply (Figure 6)
•BioDigitalPC®Cards (Check Invoice for Quantity) (Figure 7)

2.3 Environment
The system is intended to be used in an environmentally controlled and secured facility. The
following system components are required for installation and remote-control operation.
•Rack Slides (not provided)
•Remote KVM Transceiver Unit (purchased separately)
•Fiber Optic cable (length determined by the end user)
•Laptop or PC with an Ethernet NIC for Remote Control Operation
•Laptop or PC with a Serial Communications Port for Switch Management
•Routers with 10G SFP+ Port
2.4 System Operations
The SR20-FDD can operate unattended once is properly installed and configured for remote
KVM operation. The remote users can have as much control of each PC Card as allowed by the
system administrator. Each user may be able to login and logout of the PC Card and operate
applications also as allowed by the System Administrator. However, System power controls and
switch management functions are not available to the user and must be accomplished from a
PC or laptop connected to the power and switch management ports on the rear panel of the
unit. These functions are password protected and available only to the System Administrator.

3Installing, Starting and Stopping the
System
3.1 Installing the System
When installing the SR20-FDD into a rack, the selected location should meet environmental
standards as described below.
Rack Space and Airflow Considerations
To allow for adequate airflow, technicians should observe the following space and airflow
requirements when deciding where to install a rack.
• Leave a minimum clearance of 36in (91.4cm) in front of the rack.
• Leave a minimum clearance of 20in (50.8cm) behind the rack.
Temperature Considerations
Your SR20-FDD is designed to operate at room temperature with its self-contained cooling.
Power Considerations
When properly configured and installed the SR20-FDD can draw up to 800 Watts (400 Watts on
average) depending on the number, load, and version of the BioDigitalPC®s used.
•To prevent improper cooling of equipment, do not block the fans.
•Clean the front fan filters periodically (at least once a month).
•If the system is intended to operate from an Uninterrupted Power Supply (UPS) power
source, ensure that the UPS unit has enough capacity to run the system.
3.2 Installing the SR20-FDD into a rack
The SR20-FDD does not ship with rack rails. The rails must be provided by the end user; follow
the rail and rack manufacturers installation instructions.
3.3 Installing System Components
BioDigitalPC®s are hot-pluggable, meaning technicians do not need to remove power to begin
adding or removing them.
Note: Only trained technicians are authorized to work inside the SR20-FDD System and access
any of the components inside the system.

3.3.1 Removing the SR20-FDD Top Cover
To add or remove BioDigitalPC®s, the SR20-FDD chassis must be pulled out of the rack, and
the SR20-FDD's Top Cover needs to be removed temporarily.
Warning: The SR20-FDD can be running while installing new server cards. However,
caution must be taken to prevent damage to the equipment as exposed circuit
components may short if any metal objects are inadvertently dropped inside the chassis.
Future versions of all electronic components will be conformal coated to prevent this from
happening.
Figure 8- SR20-FDD Rear Panel
•Step 1- Remove the center Phillips head screw.
•Step 2- Slide the top cover to the rear and lift to release the cover from the 4 side locking
pins.
3.3.2 Installing a BioDigitalPC®

3.3.4 Replacing a KVM Over Fiber PCB Stack Module
•Disconnect all cables (USB, miniDP, 5V power, and Fiber Optic)
•Remove 4 Phillips pan head 4-40 X ¼” screws located at the bottom of each corner of
the module (see Figure 12).
•Remove the KVM PCB Stack Module from the chassis.
•Install the KVM PCB Stack Module in reverse order as removal.
Warning: The 5V power cable must be installed with the proper polarity (see Figure 17).
Connecting the 5V power cable with reverse polarity will severely damage the KVM PCB.
