Appendix B Installation In a Hazardous Environment

Verifying Switch Operation

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

Caution You must connect the switch only to a DC-input power source that has an input supply voltage from 18 to 60 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged.

Caution For wire connections to the power and relay connector, you must use UL- and CSA-rated, style 1007 or 1569 twisted-pair copper appliance wiring material (AWM) wire (such as Belden part number 9318).

To wire the switch to the optional AC/DC converter, go to the “Connecting the Switch to the Power Converter” section on page B-49.

To wire the switch to a DC-input power source, follow these steps:

Step 1 Locate the power and relay connector (see Figure B-12).

Step 2 Identify the positive and return DC power connections on the connector. The positive DC power connection is labeled V, and the return is the adjacent connection labeled RT. See Figure B-12.

Step 3 Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to connect to the DC power source.

Step 4 Using an 18-gauge wire-stripping tool, strip each of the two twisted pair wires coming from each DC-input power source 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 wire. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay connector after installation.

IE 3000 Series, IEM30004PC specifications

The Cisco IEM30004PC is an integral component of the Cisco IE 3000 Series, designed specifically for deployment in harsh industrial environments. This managed Ethernet switch provides versatility, reliability, and robust performance necessary for industrial applications, supporting a range of Ethernet-enabled devices.

One of the main features of the IEM30004PC is its rugged design. The switch is built to withstand extreme temperatures, vibrations, and electromagnetic interference, making it ideal for usage in manufacturing plants, oil and gas facilities, and transportation systems. It operates within a wide temperature range of -40 to 75 degrees Celsius, ensuring dependable functionality in varying environmental conditions.

The IEM30004PC is equipped with four 10/100/1000 Gigabit Ethernet ports. These ports support both copper and fiber connections, providing flexibility for network installations. In addition, the switch supports various redundancy protocols, including Rapid Spanning Tree Protocol (RSTP) and Link Aggregation Control Protocol (LACP), which enhance network reliability and fault tolerance.

Another distinguishing characteristic of the IEM30004PC is its support for Power over Ethernet (PoE). This feature allows the switch to deliver power over the Ethernet cables to connected devices, such as IP cameras and wireless access points, eliminating the need for separate power sources and simplifying installations.

Cisco's IEM30004PC also integrates advanced security features, including 802.1X port-based authentication, Access Control Lists (ACLs), and Role-Based Access Control (RBAC). These security measures ensure that only authorized devices can connect to the network, reducing the risk of unauthorized access and enhancing overall network integrity.

For network management, the IEM30004PC supports Simple Network Management Protocol (SNMP), Cisco's Network Assistant, and other management tools. This enables centralized control and monitoring of the network, simplifying the administration and operation of industrial networks.

In summary, the Cisco IEM30004PC, as part of the IE 3000 Series, is engineered for robust performance in industrial settings. With its rugged design, multiple Gigabit Ethernet ports, PoE capabilities, and advanced security features, it is an excellent choice for organizations seeking reliable networking solutions in challenging environments. Its comprehensive management options further enhance its utility, making it an indispensable asset for modern industrial networks.
