4. Setup Guide

4.1. Physical Installation

1. Unpack the Switch: Carefully remove the switch and all accessories from the packaging.
2. Choose a Location: Select a stable, flat surface or a rack-mount location with adequate ventilation. Ensure the ambient temperature is within the operating range specified in the product datasheet.
3. Mounting (Optional): If rack-mounting, attach the provided mounting brackets to the sides of the switch using the included screws. Secure the switch into the rack.
4. Connect Power: Connect the power cord to the switch's power input and then to a grounded electrical outlet. Do not power on the switch yet.

4.2. Initial Network Connection

1. Connect to a PC: For initial configuration, connect an Ethernet cable from your computer's network adapter to any of the switch's Gigabit Ethernet ports.
2. Power On: Connect the power cord to a power source. The switch will begin its power-on self-test (POST). Wait for the system LED to indicate readiness (typically solid green).
3. Access the Web UI: By default, the switch may obtain an IP address via DHCP. If no DHCP server is present, it will use a fallback IP address (e.g., 192.168.1.254). Refer to the Quick Start Guide for the default IP address and login credentials. Open a web browser and enter the switch's IP address to access the management interface.
4. Change Default Credentials: For security, immediately change the default username and password upon first login.

5. Operating the Switch

5.1. Basic Network Connectivity

Once the switch is powered on and configured, connect your network devices (computers, servers, IP phones, access points) to the available Ethernet ports. The switch will automatically detect the connection speed and duplex mode.

5.2. Managing the Switch

The Cisco CBS350-8FP-2G is a managed switch, offering various configuration options through its web-based user interface (Web UI) or command-line interface (CLI). Common management tasks include:

• VLAN Configuration: Create and manage Virtual Local Area Networks to segment your network for improved security and performance.
• Quality of Service (QoS): Prioritize network traffic for critical applications like voice and video.
• Security Features: Configure port security, 802.1X authentication, and access control lists (ACLs) to protect your network.
• PoE+ Management: Monitor and control power delivery to connected PoE devices.
• Firmware Updates: Regularly update the switch firmware to ensure optimal performance and security.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Cisco Smart Switch.

• Keep it Clean: Periodically clean the exterior of the switch with a soft, dry cloth. Ensure ventilation openings are free from dust and debris to prevent overheating. Do not use liquid cleaners or aerosols.
• Firmware Updates: Check the Cisco support website regularly for new firmware versions. Updating firmware can provide new features, performance improvements, and security patches.
• Environmental Control: Ensure the switch operates within its specified temperature and humidity ranges. Avoid placing it near heat sources or in direct sunlight.
• Cable Management: Keep network cables organized and properly secured to prevent accidental disconnections or damage to ports.
• Backup Configuration: Regularly back up the switch's configuration to an external device. This allows for quick restoration in case of a factory reset or device replacement.

7. Troubleshooting

This section provides solutions to common issues you might encounter.

7.1. No Power / System LED Off

• Check Power Cord: Ensure the power cord is securely connected to both the switch and the electrical outlet.
• Verify Outlet: Test the electrical outlet with another device to confirm it is functional.
• Power Cycle: Disconnect the power cord, wait 10 seconds, and then reconnect it.

7.2. No Network Connectivity

• Check Cable Connections: Ensure Ethernet cables are securely plugged into both the switch port and the connected device. Verify that the link/activity LED on the switch port is illuminated.
• Verify Device Status: Ensure the connected device (PC, server, etc.) is powered on and its network adapter is enabled.
• IP Address Conflict: If manually assigning IP addresses, ensure there are no conflicts on the network.
• VLAN Configuration: If VLANs are configured, ensure the device is connected to the correct VLAN or that inter-VLAN routing is properly set up.

7.3. PoE Device Not Receiving Power

• Check PoE Compatibility: Ensure the connected device is PoE or PoE+ compatible.
• Verify Cable: Use a standard Ethernet cable (Cat5e or higher) that supports PoE.
• PoE Budget: Check the switch's PoE power budget. If too many high-power devices are connected, the switch may not be able to power all of them. Disconnect some devices or use an external power source for some.
• Port Status: Log into the switch's Web UI and verify that PoE is enabled on the specific port and that the port is not in an error state.
