Chapter 2 Switch Installation

Connecting Destination Ports

The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See Chapter 3, “Troubleshooting,” for solutions to cabling problems.

Step 5 If necessary, reconfigure and restart the switch or the target device.

Connecting to a Dual-Purpose Port

The dual-purpose port is a single port with two interfaces, one for an RJ-45 cable and another for an SFP module. Only one interface can be active at a time. If both interfaces are connected, the SFP module has priority. For more information about dual-purpose ports, see the “Dual-Purpose Ports” section on page 1-5.

Warning Class 1 laser product. Statement 1008

Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light.

Before connecting to the SFP module, be sure that you understand the port and cabling stipulations in the “Preparing for Installation” section on page 2-1. See Appendix C, “Cable and Connectors,” for information about the LC on the SFP module.

To connect to a dual-purpose port, follow these steps:

Step 1 Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot, and connect a cable to the SFP module port. See Figure 2-36.

For more information about RJ-45 connections, SFP modules, and optical connections, see the “Connecting to 10/100 and 10/100/1000 Ports” section on page 2-36, the “Installing and Removing SFP Modules” section on page 2-37, and the “Connecting to SFP Modules” section on page 2-41.

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.
