Preparing to Connect the Cisco ISA 3000

Before you connect the Cisco ISA 3000 to the devices, install the ISA 3000 according to the instructions in

Installing the Cisco ISA 3000 Industrial Security Appliance.

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network

voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some

LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

Warning

If this product will be installed in a hazardous location, read the Getting Started/Printed Document of

Compliance included in the package.

Caution

Preventing Damage to the Cisco ISA 3000

Before installation, observe these general guidelines:

• Proper ESD protection should be observed

• Ensure the device is properly grounded

Connecting the Cisco ISA 3000

• Ensure there is proper airflow around the device

Connecting a PC to the Cisco ISA 3000 For Configuration

The console connection of the ISA 3000 is not available for configuration. It is only used for troubleshooting

when directed by a support person. All configuration of the device is done through Cisco IoT Field Network

Director (FND) version 4.3 or greater.

There are two methods of connecting to the Cisco ISA 3000 in case of troubleshooting:

• Connect a PC to the console connector of the Cisco ISA 3000 and launch a console terminal to use the

CLI. ASA has a full CLI set, however, FTD only supports a setup script plus a few commands.

• Connect the PC to the Cisco ISA 3000 management sub-network which will then receive an IP address

through DHCP.

Step 1 Choose which console connection will be used. In the following figure, Item 1is the RJ-45 console connector, and item

2is the mini-USB connector.

Figure 1: Console Connection Ports

Step 2 If the mini-USB connector is being used, the protective cover will need to be removed first. The red arrow in the following

figure shows the location of the cover. Remove the cover with a Phillips screw driver and set it aside to be reinstalled

after completing the configuration.

Figure 2: mini-USB Cover

Step 3 Connect the mini-USB side of a cable to the USB Console port on the Cisco ISA 3000.

Step 4 Connect the opposite end of the mini-USB cable to the USB port on your PC. If your PC warns you that you do not have

the proper drivers to communicate with the device, you can obtain them from your computers manufacturer, or go here:

Connecting to DC Power

Installation of the equipment must comply with local and national electrical codes. Statement 1074

Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Statement 1003

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement

1022

Warning

You connect DC power to the device through the front panel connectors. The device has a dual-feed DC power

supply; two connectors provide primary and secondary DC power (DC-A and DC-B).

Each power connector has an LED status indicator. The device power connectors are attached to the device

chassis. Each power connector has screw terminals for terminating the DC power. All connectors are attached

to the device front panel with the provided captive screws.

The power connector labeling is on the panel. The positive DC power connection is labeled “+”, and the return

connection is labeled “–”.

The device can operate with a single power source or with dual power sources. When both power sources are

operational, the device draws power from the DC source with the higher voltage. If one of the two power

sources fail, the other continues to power the device.

To connect DC power to your Cisco ISA 3000, follow these steps:

Step 1 Locate the two power connectors on the device front panel labeled DC-A and DC-B.

Figure 3: Power Connector

Step 2 Identify the connector positive and return DC power connections. The "+" is the Positive DC power connection, and the

"-" is the Return DC power connection.

Step 3 Measure two strands of twisted-pair copper wire long enough to connect the power converter to the DC power source.

For DC connections from the power converter to the DC source, use 18 to 20 AWG (2.6mm) twisted-pair copper wire.

Connecting the Cisco ISA 3000

Connecting to DC Power

Step 4 Using a 18-gauge (1.02mm) wire-stripping tool, strip the ground wire and both ends of the twisted pair wires to 0.25 inch

(6.3 mm) ± 0.02 inch (0.5 mm). See the following figure, number 1. Do not strip more than 0.27 inch (6.8 mm) of insulation

from the wires. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay

connector after installation.

Figure 4: Stripping the Power Connection Wire

Step 5 Remove the two captive screws that attach the power connector to the device, and remove the power connector. Remove

both connectors if you are connecting to two power sources.

Step 6 On the power connector, insert the exposed part of the positive wire into the connection labeled “+” and the exposed part

of the return wire into the connection labeled “–”. The "+" is the Power source positive connection, and the "-" is the

Power source return connection. See the following figure.

Ensure that you cannot see any wire lead. Only wire with insulation should extend from the connector.

Note

Step 7 Use a ratcheting torque flathead screwdriver to torque the power connector captive screws (above the installed wire leads)

to 2 in-lb (0.23 N-m). See the following figure.

Do not over-torque the power connector’s captive screws. The torque should not exceed 2 inch-lbs (0.23 N-m).

Warning

Step 8 Connect the other end of the positive wire to the positive terminal on the DC power source, and connect the other end of

the return wire to the return terminal on the DC power source.

When you are testing the device, one power connection is sufficient. If you are installing the device and are using a second

power source, repeat steps 4 through 8 using the second power connector.

Attaching the DC Power Connectors to the Device

To attach the power connectors to the front panel of the device, follow these steps:

Failure to securely tighten the captive screws can result in an electrical arc if the connector is accidentally

removed. Statement 397

Warning

Connecting the Cisco ISA 3000

Attaching the DC Power Connectors to the Device

When you connect or disconnect the power and/or alarm connector with power applied, an electrical

arc can occur. This could cause an explosion in hazardous area installations. Be sure that all power is

removed from the device and any other circuits. Be sure that power cannot be accidentally turned on or

verify that the area is nonhazardous before proceeding. Statement 1058

Warning

1. Insert one power connector into the DC-A receptacle on the device front panel, and the other into the

DC-B receptacle.

2. Use a ratcheting torque flathead screwdriver to tighten the captive screws on the sides of the power

connectors to 2 in-lb (0.23 N-m).

3. When you are testing the device, one power source is sufficient. If you are installing the device and are

using a second power source, repeat this procedure for the second power connector (DC-B), which installs

just below the primary power connector (DC-A).

4. When you are installing the device, secure the wires coming from the power connector so that they cannot

be disturbed by casual contact. For example, use tie wraps to secure the wires to the rack.

Connecting Alarm Circuits

After the device is installed, you are ready to connect the DC power and alarm connections.

The device has two alarm input and one alarm output relay circuits for external alarms. The alarm input circuits

are designed to sense if the alarm input is open or closed relative to the alarm input reference pin. Each alarm

input can be configured as an open or closed contact. The alarm output relay circuit has a normally open and

a normally closed contact.

Alarm signals are connected to the device through the six-pin alarm connector. Three connections are dedicated

to the two alarm input circuits: alarm input 1, alarm input 2, and a reference ground. An alarm input and the

reference ground wiring connection are required to complete a single alarm input circuit. The three remaining

connections are for the alarm output circuit: a normally open output, a normally closed output, and a common

signal. An alarm output and the common wiring connection are required to complete a single alarm output

circuit.

The alarm connectors are on the device panel and are detailed in the following table:

ConnectionPin

Alarm Output Normally Open (NO) connection1

Alarm Output Common connection2 (COM)

Alarm Output Normally Closed (NC) connection3

Alarm Input 24 (IN2)

Alarm Input Reference Ground connection5 (REF)

Alarm Input 16 (IN1)

Explosion Hazard—Do not connect or disconnect wiring while the field-side power is on; an electrical

arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is

removed or that the area is nonhazardous before proceeding. Statement 1081

Warning

The input voltage source of the alarm output relay circuit must be an isolated source and limited to less

than or equal to 24 VDC, 1.0 A or 48 VDC, 0.5 A.

Caution

Wire connections to the power and alarm connectors must be UL- and CSA-rated, style 1007 or 1569

twisted-pair copper appliance wiring material (AWM) wire (such as Belden part number 9318).

Note

Wiring the External Alarms

To wire the device to an external alarm device, follow these steps:

Step 1 Remove the captive screws that hold the alarm connector on the device, and remove the connector from the device chassis.

Step 2 Measure two strands of twisted-pair wire (18-to-20 AWG) long enough to connect to the external alarm device.

You can choose between setting up an external alarm input or output circuit.

Step 3 Use a wire stripper to remove the casing from both ends of each wire to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm).

Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than the recommended amount

of wire can leave exposed wire from the alarm connector after installation.

Step 4 Insert the exposed wires for the external alarm device into the connections based on an alarm input or output circuit setup.

For example, to wire an alarm input circuit, complete the IN1 and REF connections as shown in the following figure:

Connecting the Cisco ISA 3000

Wiring the External Alarms

IN1 - External device connection 11

REF - External device connection 22

Step 5 Use a ratcheting torque flathead screwdriver to tighten the alarm connector captive screw (above the installed wire leads)

to 2 in-lb (0.23 N-m).

Do not over-torque the power and alarm connectors’ captive screws. Do not exceed 2 inch-lbs (0.23 N-m)

torque.

Note

Step 6 Repeat the above steps to insert the input and output wires of one additional external alarm device into the alarm connector.

What to do next

The following figure shows the completed wiring for two external alarm devices. The first alarm device circuit

is wired as an alarm input circuit; the IN1 and REF connections complete the circuit. The second alarm device

circuit is wired as an alarm output circuit that works on a normally open contact basis; the NO and COM

connections complete the circuit.
