  1. Insert the alarm connector into the receptacle on the switch front panel.

  2. Use a torque flathead screwdriver to tighten the captive screws on the sides of the alarm connector.

Connect Network Ports

These section provide more information about connecting to the network ports:

Connect to 10/100/1G Ports

The switch 10/100/1G ports automatically configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no communication.


Note


For Rail and Smart Grid compliance, SF/UTP cables must be used for Ethernet ports.


To maximize performance, choose one of these methods for configuring the Ethernet ports:

  • Let the ports autonegotiate both speed and duplex.

  • Set the port speed and duplex parameters on both ends of the connection.

Procedure


Step 1

To connect to 10BASE-T, 100BASE-TX or 1000BASE-T devices, follow these steps:

  1. When connecting to workstations, servers, routers, and Cisco IP phones, connect a straight-through cable to an RJ-45 connector on the front panel.

  2. When connecting to 1000BASE-T-compatible devices, use a twisted four-pair, Category 5 or higher cable.

  3. The auto-MDIX feature is enabled by default. For configuration information for this feature, see the Cisco IE3500/IE3505 switch Software Configuration Guide for the appropreate software release.

Step 2

Connect the other end of the cable to an RJ-45 connector on the other device.

The port LED turns on when both the switch and the connected device have established a link.

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This can take up to 30 seconds, and then the port LED turns green.


What to do next

If the port LED does not turn on:

  • The device at the other end might not be turned on.

  • There might be a cable problem or a problem with the adapter installed in the attached device. See Troubleshooting for solutions to cabling problems.

  • Reconfigure and reboot the connected device if necessary.

  • Repeat Steps 1 through 3 to connect each device.

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 guidelines in Prepare for Installation.


To connect a fiber-optic cable to an SFP module, follow these steps:

Procedure


Step 1

Insert one end of the fiber-optic cable into the SFP module port.

Step 2

Insert the other cable end into a fiber-optic receptacle on a target device.

Step 3

Observe the port status LED:

  • The LED turns green when the switch and the target device have an established link.

  • 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 Troubleshooting for solutions to cabling problems.

Step 4

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


Verify Switch Operation

Before installing the switch in its final location, power on the switch, and verify that the switch powers up and boots.

Where to Go Next

Even if the default configuration is satisfactory, you must set a new password before connecting the switch to a network. You can use any of these management options to to configure the switch.

  • Start the Web UI. This is an easy-to-use web interface that offers quick configuration and monitoring. You can access the Web UI from anywhere in your network through a web browser. For more information, see the Software Configuration Guide and the Web UI online help.

  • Use the CLI to configure the switch as an individual switch from the console.

  • Start the Common Industrial Protocol (CIP) management tool. You can manage an entire industrial automation system with the CIP-based tools.
