3.2 ການຕິດຕັ້ງທາງດ້ານຮ່າງກາຍ

1. ການຈັດວາງ: 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.
2. ການເຊື່ອມຕໍ່ພະລັງງານ: 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.
3. ການຕໍ່ດິນ: 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.
4. ການເຊື່ອມຕໍ່ເຄືອຂ່າຍ:
   • ຜອດອີເທີເນັດ (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.

• ການປົກປ້ອງພະລັງງານ: As mentioned in the setup, using an Uninterruptible Power Supply (UPS) is crucial to protect the switch and connected devices from power fluctuations, surges, and outages.
• ເງື່ອນໄຂສິ່ງແວດລ້ອມ: Ensure the switch operates within its specified environmental conditions (temperature, humidity) to prevent damage.

6. ການແກ້ໄຂບັນຫາ

This section provides solutions to common issues you might encounter with your switch.

6.1 ບໍ່ມີພະລັງງານ

• ໃຫ້ແນ່ໃຈວ່າສາຍໄຟໄດ້ເຊື່ອມຕໍ່ກັບທັງສະວິດ ແລະ ປລັກໄຟທີ່ໃຊ້ງານໄດ້ຢ່າງແໜ້ນໜາແລ້ວ.
• ກວດສອບວ່າປລັກສຽບໄຟເຮັດວຽກໄດ້ໂດຍການສຽບໃສ່ອຸປະກອນອື່ນ.
• Check the Power LED on the front panel. If it's off, the switch is not receiving power.

6.2 ບໍ່ມີການເຊື່ອມຕໍ່/ກິດຈະກຳໃນທ່າເຮືອ

• Check the Ethernet cable connection between the switch port and the connected device. Try a different cable.
• ໃຫ້ແນ່ໃຈວ່າອຸປະກອນທີ່ເຊື່ອມຕໍ່ນັ້ນເປີດຢູ່ ແລະ ເຮັດວຽກຢ່າງຖືກຕ້ອງ.
• 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 ຄວາມໄວເຄືອຂ່າຍຊ້າ

• 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.
• ກວດສອບການຈະລາຈອນເຄືອຂ່າຍຫຼາຍເກີນໄປ ຫຼື ແອັບພລິເຄຊັນທີ່ໃຊ້ແບນວິດສູງ.

6.4 ອຸປະກອນ PoE ບໍ່ໄດ້ຮັບພະລັງງານ

• 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.
• ລອງເຊື່ອມຕໍ່ອຸປະກອນ PoE ກັບພອດ PoE+ ອື່ນ.
