Users may encounter situations where their switch does not appear to start up successfully or not power up at all. Troubleshooting this process has several phases:
- Physical connections check
- Power type check
- LED indicator check
- Additional troubleshooting
- RMA criteria
Phase 1: Physical connections check
Confirm DC power is connected to P1 and/or P2 terminals (positive lead) as well as the “-” terminal (negative/return). Ensure the power block is firmly seated into the socket.

Phase 2: Power type check
Confirm DC power in the range of 10 to 30 Volts is supplied. The recommended Voltage is 24VDC.
Phase 3: LED indicator check
When power is applied, the P1 and/or P2 LEDs should be illuminated, depending upon which terminals are being supplied with power. On managed switches (part numbers SL(X)-xMS or xMG), the status LED should also flash for several seconds and then illuminate steadily. This indicates that the switch has begun the startup process. Unmanaged switches (SL(X)-xES) do not have a status LED. Switch startup times are as follows:
- SL(X)-xMS or -xMG – roughly 45 seconds
- SL(X)-xRS – Roughly 10 seconds
- SL(X)-xES – roughly 5 seconds
After these times, the port LEDs should accurately indicate Link and Traffic status. The OK LED is a configurable alarm. Depending upon your configuration, this LED may be on or off.

Phase 4: Additional troubleshooting
Size of power supply
It is important to ensure that the power supply used to power your Sixnet switch is large enough. Particularly with switches that have many fiber ports, we recommend using one power supply per switch unless your power supply is very high capacity. Sixnet recommends reviewing the power input ratings on the label of your unit and allocating 2-3 times this capacity for the initial startup current.
If you are having problems with switches not always powering up or repeatedly rebooting, try removing all equipment but your Sixnet switch from the supply.
Phase 5: RMA criteria
After progressing though phases 1-4, if the switch still does not power up correctly, there may be a hardware failure with your switch. Please gather the following information and an RMA request will be generated:
- Full model number
- Serial number and/or Date code (older units may only have a date code)
- Any information related to the failure, such as potential cause if known
