Template:Networking device manual unmanaged switch recovery troubleshooting

Summary

{{{name}}} is an unmanaged switch without active operating system running to control inside processes. All work is done by integrated chips, which has built-in logic to control switching and PoE operations.

This chapter contains information of possible recovery and troubleshooting options for a {{{name}}} unmanaged switch.

Ethernet port LEDs not lighting up

1. Issue

   {{{name}}} green Ethernet port LED is not lighting up (orange LED lit)

   Solution

   {{{name}}} switch green Ethernet port LED indicates Gigabit connection with device. Check if connected device network card supports Gigabit speeds or software configuration is not limited to 10/100 Mbps.

2. Issue

   {{{name}}} is not powered up

   Solution

   Check the front panel power LED if it is lit. If not, try to use other 7-57 VDC power supply, which can provide at least 2 W of power. More information about {{{name}}} powering options check here

3. Issue

   Connected device is not powered up

   Solution

   Check if connected device is powered up and working properly

4. Issue

   Bad cabling between {{{name}}} and connected device

   Solution

   Use other Ethernet cable to connect {{{name}}} with device

5. Issue

   Defected {{{name}}} Ethernet port

   Solution

   Use other free {{{name}}} Ethernet port to connect switch with device. If device establishes connection with {{{name}}} using other Ethernet port, {{{name}}} is defective and must be sent for service inspection and repairs. Check [[{{{name}}}_Device_Recovery_and_Troubleshooting_Options#RMA | RMA]] section for further instructions

6. Issue

   Defected {{{name}}} switch

   Solution

   If {{{name}}} Ethernet port LED are not lighting up after doing above mentioned actions, {{{name}}} is defective and must be sent for service inspection and repairs. Check [[{{{name}}}_Device_Recovery_and_Troubleshooting_Options#RMA | RMA]] section for further instructions

Connected devices have no internet

1. Issue

   Connected router/modem do not have internet connection

   Solution

   Check connected router/modem users manual how to diagnose and troubleshoot internet connection issue

2. Issue

   Bad cabling between {{{name}}} and router/modem

   Solution

   Check cabling from {{{name}}} to router/modem. If link between devices is established, orange LED at connected Ethernet port must be lit (LEDs meaning). If LED has not lit, change Ethernet cable, connect other router/modem and check again

3. Issue

   Bad cabling between {{{name}}} and connected device

   Solution

   Check cabling from {{{name}}} to connected device. If link between devices was established, orange LED at connected Ethernet port must be lit (LEDs meaning). If LED has not lit, change Ethernet cable and check again

4. Issue

   Defected {{{name}}} switch

   Solution

   Connect device directly to router/modem and check if internet connection was established. If device gets access to internet, when directly connected to router/modem. Try turn switch off and on (restart), if issue persists, {{{name}}} is defective and must be sent for service inspection and repairs. Check [[{{{name}}}_Device_Recovery_and_Troubleshooting_Options#RMA | RMA]] section for further instructions

Connected device not powered via PoE

1. Issue

   Connected device to {{{name}}} is not powered via PoE

   Solution I

   Check if connected device supports 802.3af and/or 802.3at PoE standard(s)

   Solution II

   Check if {{{name}}} is powered with PSU, which outputs 44 VDC or higher voltages and can provide at least 2 W + connected device needed power

2. Issue

   All PoE devices and switch lost power after connecting more than two device to {{{name}}}

   Solution

   {{{name}}} supports 802.3at standard, were each port can supply up to 30 W of power at PSE with total power budget of 120 W per all 4 ports. Standard PSU, which comes in the box with {{{name}}}, provides ~65 W power and limits power budget to ~60 W. If all connected devices to PoE ports combined required more that 60 W of power, PSU was overloaded and turned itself off.
   If full 120 W power budget is necessary, {{{name}}} must be powered with PSU, which can provide at least 130 W power at 44 VDC or higher voltages

RMA

If conventional recovery methods do not help, you may need to send the device to warranty for repair. The warranty process is described here.
