Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may
require further evaluation by Certification Agencies. The following items must be
considered.
1. The ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. The maximum temperature for the equipment in this environment is
60°C. Consideration should be given to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due
to uneven loading.
Input Supply
Check nameplate ratings to assure there is no overloading of supply circuits that could
have an effect on overcurrent protection and supply wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct
connections to the branch circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be
serviced by authorized personnel only.
• Shock Hazard - Do Not Enter
• Lithium Battery
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace
only with same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer's instructions.
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet
and contact qualified service personnel:
1. If the power cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain
or water.

ii
Warnings and Cautions
Two Power Supply Cables
Note that some AFS series units feature two separate power inlets and a separate power
supply cable for each power inlet. Make certain to disconnect all power supply cables
from their power source before attempting to service or remove the unit.
Disconnect Power Before Servicing
Before attempting to service or remove this unit, please make certain to disconnect the
power supply cable from the power source.

1. Introduction
The AFS-16-1 is a versatile switching system, designed for applications that require
routing of analog or digital signals between a common RJ45 jack and “A” and “B RJ45
jacks. The AFS is ideal for switching RS232, RS422/485, Ethernet/UTP or telephone
lines.
The system consists of a Card Rack, one Power Supply Module, one Control Module,
and up to 16 Circuit Modules. Each Circuit Module is capable of switching all 8 pins of
the Common RJ45 jack between Jack “A” or Jack “B”. Each card can be switched by
alarm, manually, or by command.
The AFS includes an assortment of alarm features, which allow the unit to monitor
temperature, power interruptions, and invalid access attempts and then notify you
via Email, text message, Syslog message or SNMP trap when critical conditions are
detected. The AFS can also monitor device response to ping commands and then
switch A/B paths and provide notification when devices fail to respond.
Note: For instructions regarding configuration and operation of the AFS Series
Device, please refer to the AFS Firmware Guide

2. Unit Description
The AFS consists of a frame unit, one Dual Power Supply Module, one Control Module,
and up to sixteen Circuit Modules.
2.1. The Dual Power Supply Module
The Dual Power Supply Module, shown in Figure 2.1, provides AC power used by the
Control Module and Circuit Module(s). The AFS will always include one Dual Power
Supply Module. Note that the Power Supply Module is not designed to be removed
from the AFS Rack Assembly.
The Power Supply Module faceplate includes the following:
Power Switch and ON Indicator
Power Inlets: (Not Shown) Two (2) IEC320-C14 AC inlets (located on the back
panel of the Dual Power Supply Module) which are used to connect the AFS to an
appropriate power source.
Power Supply Indicators: Two LEDs (located on the back panel of the Dual Power
Supply Module), which will light when connected to an active power source. Note
that there is one LED for Inlet "A" and one LED for Inlet "B".

2.2. The Control Module
The Control Module, shown in Figure 2.2, coordinates switching of the individual
Circuit Modules. The Control Module includes a Master A/B Gang Switch, status LEDs,
a 10/100Base-T Ethernet connector and an RJ-45 RS232 Serial Port for connection
to your PC, control device or external modem. An AUX jack is provided to allow
connection to a monitored line and optional external alarm. The AFS always includes
one Control Module.

Figure 2.2: The Control Module
The AFS Control Module includes the following components:
Ethernet Port: An RJ45 Ethernet port for connection to your TCP/IP network. Note
that the AFS features a default IP address (192.168.168.168). This allows you to
establish an SSH connection with the unit without first assigning an IP address.
Note that the Network Port also includes two, small LED indicators for Link and Data
Activity.
Master A/B Gang Switch: Allows manual control of A/B switching at up to sixteen
Circuit Modules. Note that the Master A/B Gang Switch can be disabled as
described in Section 4.5.
ALM Indicator: The ALM Indicator will light when Monitor Input Alarm is triggered.

Unit Description
Reset Switch: To reinitialize the AFS, hold the Reset Switch in the "down"
position for approximately five seconds. When the AFS is reset, all users will be
disconnected from the AFS and the operating system will be reloaded.
RS232 Connector: An RJ-45 Serial Port for connection to your PC, control device,
or external modem. Please refer to Appendix A for a description of the RS232
interface.
AUX Connector: (Not Shown) A five terminal quick connector, located on the back
edge of the Control Module board. The AUX Connector can be used in conjunction
with the Monitor/Alarm Input feature to generate an alarm when the status of pin 4
changes. In addition, pins 1 through 3 on the AUX Connector can also be used to
switch a connected device On or Off in response to signal changes at Pin 4.
Notes:
• The Monitor Input signal (Pin 4) is always measured relative to the signal at
the common ground (Pin 5).
• A "Low" signal should be between Zero (0) Volts and -48 Volts and a "High"
signal should be between +5 Volts and +48 Volts.
Release Pin: A snap-lock pin that is used to secure the Control Module to the
AFS frame.
Monitor Input Level Jumper: (Not Shown) A jumper located on the Control
Module board, which is used to configure the AUX Connector for use with the
Monitor/Alarm Input feature. The Monitor Input Level Jumper selects the non-active
state for the Monitor/Alarm Input feature. When the jumper is set in the "1" position
(normally high,) the Monitor/Alarm Input feature can generate an alarm when the
Monitor Input signal goes low. When the jumper is set in the "0" position (normally
low,) the Monitor/Alarm Input feature can generate an alarm when the Monitor Input
signal goes high.

Figure 2.3: The Circuit Module
The AFS Circuit Module includes the following components:
A/B Switch: Each A/B Switch can be manually switched, or activated by
commands sent to the Control Module. The A/B Switch can also be operated by
the Control Module’s Master A/B Switch.
“A” Connector: An RJ45 Port, used for connection to your primary line.
“C” Connector: An RJ45 Port, used for connection to a common line.
“B” Connector: An RJ45 Port, used for connection to your fallback line.
Release Pin: Used to secure the Circuit Module to the AFS frame.
A/B Switch Jumper: (Not Shown) A jumper, located on the Circuit Module board,
which is used to enable/disable the individual Circuit Module’s response to the
Master A/B Gang Switch as described in Section 4.5.2.
