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

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

   Solution

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

4. 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

5. 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 has 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 router/modem and {{{name}}}

   Solution

   Check cabling from router/modem to {{{name}}}. 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 connected device and {{{name}}}

   Solution

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

2. Issue

   After connecting more than two device {{{name}}} all connected PoE devices lost power

   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 connected to PoE 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}}} switch must be powered with PSU which can provide 130 W po 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.
