3. Instalacja i konfiguracja

3.1 Rozpakowanie i kontrola

Carefully unpack the switch and inspect it for any damage during shipping. Report any damage to your vendor immediately.

3.2 Przygotowanie miejsca

Before installation, ensure the installation site meets the environmental requirements. The switch dimensions are approximately 17.5 x 15.2 x 1.75 inches (44.45 x 38.61 x 4.45 cm) or 17.5"L x 17.5"W x 2.9"H (44.45 x 44.45 x 7.37 cm) depending on specific mounting. Allow sufficient space for cabling and ventilation.

3.3 Montaż przełącznika

The switch can be mounted in a standard 19-inch equipment rack. Use the provided rack-mount brackets and screws to secure the switch. Ensure the switch is level and securely fastened.

3.4 Podłączanie zasilania

1. Podłącz przewód zasilający do złącza zasilania prądem zmiennym znajdującego się na tylnym panelu przełącznika.
2. Podłącz drugi koniec przewodu zasilającego do uziemionego gniazdka sieciowego.
3. Sprawdź, czy dioda LED systemu na panelu przednim świeci, wskazując, że zasilanie jest dostarczane.

3.5 Podłączanie urządzeń sieciowych

Connect network devices (computers, IP phones, wireless access points) to the 48 10/100/1000Base-T Ethernet ports using standard Ethernet cables. For devices requiring power, connect them to the PoE+ enabled ports. Use SFP modules in the expansion slots for fiber optic or other uplink connections.

3.6 Dostęp do konfiguracji początkowej

For initial configuration, connect a console cable from your management workstation to the console port on the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with appropriate settings (typically 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control) to access the command-line interface (CLI).

4. Działanie

4.1 Włączanie/wyłączanie zasilania

Once connected to a power source, the switch will automatically power on. There is no physical power button. To power off, disconnect the power cord. For proper shutdown, it is recommended to save configurations before disconnecting power.

4.2 Wskaźniki LED

The front panel of the switch features various LEDs to indicate system status and port activity:

• Dioda systemowa: Indicates overall system health (e.g., green for normal operation, amber for issues).
• RPS LED: Indicates the status of the Redundant Power System (if installed).
• Dioda LED stosu: Indicates the status of the FlexStack connection.
• Diody stanu portu: Each Ethernet port has an LED to indicate link status (on/off) and activity (blinking). Green typically indicates a 1000 Mbps link, amber for 10/100 Mbps.
• Dioda PoE: Indicates Power over Ethernet status for the respective port.

4.3 Zasilanie przez Ethernet Plus (PoE+)

The switch supports PoE+ (802.3at) on all 48 Ethernet ports, providing up to 30W of power per port to compatible devices such as IP phones, wireless access points, and surveillance cameras. Ensure connected devices are PoE+ compliant for optimal performance.

4.4 Cisco FlexStack

The Cisco Catalyst 2960S-48LPS-L supports FlexStack technology, allowing multiple switches to be stacked together to operate as a single logical unit. This simplifies management and increases network scalability. Refer to the Cisco documentation for detailed FlexStack configuration and cabling instructions.
