2. Package Contents

Verify that your package contains the following items:

• Cisco Business CBS350-24XT Managed Switch
• Power cord or adapter
• Mounting hardware (for rack or wall mounting)
• Quick Start Guide

3. Setup and Installation

3.1 Site Preparation

Before installation, ensure the installation site meets the following requirements:

• Adequate ventilation to prevent overheating.
• Stable, level surface for desktop placement or a standard 19-inch rack for rack mounting.
• Proximity to a grounded power outlet.
• Operating temperature and humidity within specified ranges (refer to specifications).

3.2 Mounting the Switch

The CBS350-24XT switch can be installed on a desktop or mounted in a standard 19-inch equipment rack using the included mounting hardware.

Desktop Installation:

1. Place the switch on a flat, stable surface.
2. Ensure sufficient space around the switch for airflow.

Rack Installation:

1. Attach the provided rack-mount brackets to the sides of the switch using the screws.
2. Secure the switch into the rack using appropriate rack screws.

3.3 Connecting Power

1. Connect the power cord to the power inlet on the rear of the switch.
2. Plug the other end of the power cord into a grounded electrical outlet.
3. The switch will power on automatically. Observe the Power LED on the front panel; it should illuminate green.

3.4 Connecting Network Devices

1. Connect your network devices (servers, workstations, access points) to the 10GE RJ-45 ports on the front panel using standard Ethernet cables.
2. For uplink connections to other switches or routers, use the 10G SFP+ ports with compatible SFP+ transceivers and fiber optic cables.
3. Observe the Link/Act LEDs for each port; they should illuminate when a valid connection is established and blink during data activity.

4. Operating the Switch

4.1 Initial Configuration

The CBS350-24XT switch can be configured via a web-based graphical user interface (GUI) or a command-line interface (CLI) through a console port.

Web-based GUI:

1. Connect a computer to any of the switch's Ethernet ports.
2. Configure your computer's IP address to be in the same subnet as the switch's default IP address (refer to the Quick Start Guide for default IP).
3. Open a web browser and enter the switch's default IP address.
4. Log in using the default credentials (refer to the Quick Start Guide).
5. Follow the on-screen wizard for initial setup, including changing default passwords and configuring basic network settings.

4.2 Cisco Business Mobile App

Manage your Cisco Business network devices, including the CBS350-24XT switch, from your mobile device using the Cisco Business Mobile App.

The app allows for quick setup of local networks, provides network insights such as connected clients and application usage, and supports various Cisco Business network and switch products.

4.3 Key Features

• Layer 3 Dynamic Routing: Supports advanced routing protocols for efficient data forwarding across complex networks.
• VLANs (Virtual Local Area Networks): Segment your network for improved security and performance.
• QoS (Quality of Service): Prioritize network traffic for critical applications.
• Security Features: Includes IPv4 and IPv6 routing, advanced threat protection with IPv6 first hop security, and access control lists (ACLs).
• Stacking: Up to 4 units (10G uplink module) for simplified management and increased capacity.

5. Power over Ethernet (PoE+)

The CBS350-24XT switch supports Power over Ethernet Plus (PoE+) on select models, allowing it to deliver power to compatible devices (such as IP phones, wireless access points, and IP cameras) directly over the Ethernet cable. This eliminates the need for separate power outlets for these devices, simplifying deployment and reducing cabling.

6. Maintenance

6.1 Firmware Updates

Regularly check the Cisco support website for the latest firmware updates. Keeping your switch's firmware up-to-date ensures optimal performance, security, and access to new features. Follow the instructions provided with the firmware update package for a safe upgrade process.

6.2 Cleaning

To maintain proper airflow and prevent dust buildup, periodically clean the switch's vents and exterior surfaces with a soft, dry cloth. Do not use liquid or aerosol cleaners directly on the switch.

6.3 Environmental Considerations

Ensure the switch operates within its specified temperature and humidity ranges. Avoid placing the switch near heat sources or in areas with excessive dust or moisture.

7. Troubleshooting

This section provides solutions to common issues you might encounter with your CBS350-24XT switch.

7.1 Power LED is Off

• Check if the power cord is securely connected to both the switch and the electrical outlet.
• Verify that the electrical outlet is functional by plugging in another device.
• Ensure the power supply unit (if external) is properly connected and functioning.

7.2 No Network Connectivity

• Check the Link/Act LEDs on the switch ports. If a LED is off, verify the Ethernet cable connection to the device and the switch. Try a different cable.
• Ensure the connected device is powered on and functioning correctly.
• Verify network settings (IP address, subnet mask, gateway) on the connected device.
• If using SFP+ ports, ensure compatible transceivers are used and fiber optic cables are correctly connected.

7.3 Unable to Access Web GUI

• Ensure your computer's IP address is in the same subnet as the switch's management IP address.
• Verify that you are using the correct IP address for the switch.
• Clear your browser's cache or try a different browser.
• If the switch was recently reset or configured, try the default IP address and credentials.

7.4 Factory Reset

If you encounter persistent issues or forget the management password, you may need to perform a factory reset. Refer to the Quick Start Guide or Cisco documentation for the specific procedure, as this will erase all configurations and restore default settings.
