3. Nastavení a instalace
This section outlines the basic steps for physically installing and connecting your TP-Link Omada SG2428P switch. The switch can be deployed as a desktop unit or rack-mounted.
3.1 Obsah balení
- TP-Link Omada SG2428P Switch Unit
- Napájecí kabel
- Mounting Brackets (for rack-mounting)
- Uživatelská příručka / Instalační průvodce
3.2 Fyzická instalace
- Umístění: Choose a stable, level surface for desktop placement or an appropriate rack unit for rack-mounting. Ensure adequate ventilation around the switch to prevent overheating.
- Připojení napájení: Connect the provided power cord to the AC power inlet on the rear panel of the switch and then to a power outlet. It is highly recommended to connect the switch to an Uninterruptible Power Supply (UPS) to protect against power surges and outages.
- Základy: For optimal safety and protection against electrical surges, ensure the switch is properly grounded. Connect a grounding wire (not always included) to the grounding screw on the rear panel and to a suitable ground source.
- Připojení k síti:
- Ethernetové porty (1-24): Connect your network devices (e.g., computers, access points, IP cameras, VoIP phones) to the RJ45 ports using standard Ethernet cables. These ports support PoE+ for compatible devices.
- SFP Slots (25-28): Insert compatible SFP modules into the SFP slots for fiber optic connections to other network devices or an upstream switch/router.

6. Řešení problémů
This section provides solutions to common issues you might encounter with your switch.
6.1 Bez napájení
- Ujistěte se, že je napájecí kabel bezpečně připojen k přepínači i k funkční zásuvce.
- Ověřte funkčnost elektrické zásuvky zapojením jiného zařízení.
- Check the Power LED on the front panel. If it's off, the switch is not receiving power.
6.2 Žádné spojení/aktivita na portu
- Check the Ethernet cable connection between the switch port and the connected device. Try a different cable.
- Ujistěte se, že připojené zařízení je zapnuté a funguje správně.
- Verify the Link/Act LED for the specific port. If it's off, there's no link.
- For SFP ports, ensure the SFP module is correctly inserted and compatible, and the fiber optic cable is properly connected.
6.3 Pomalá rychlost sítě
- Check the Speed LED for the port. If it's yellow (10/100 Mbps) instead of green (1000 Mbps), ensure both the switch port and the connected device support Gigabit Ethernet.
- Use high-quality Ethernet cables (e.g., Cat5e or Cat6) for Gigabit speeds.
- Ensure there are no network loops.
- Zkontrolujte nadměrný síťový provoz nebo aplikace náročné na šířku pásma.
6.4 Zařízení PoE nepřijímá napájení
- Verify that the connected device is PoE-compatible (802.3at/af standard).
- Check the PoE LED for the specific port. If it's off, no PoE power is being delivered. If it's flashing, there might be an over-budget situation or a fault.
- Ensure the total PoE budget (250W) of the switch is not exceeded by all connected PoE devices.
- Try connecting the PoE device to a different PoE+ port.
