This article describes some basic troubleshooting steps when the switch/router/firewall does not power on.

In these cases, we need to do hardware troubleshooting:

1. Change the power cord.
2. Change the power source.
3. Reseat the PSU (if possible).
4. Move the PSU from the current slot to another available or another switch (if possible).

If all the above steps fail to fix the issue, we need to open a JTAC case to request an RMA for either the PSU or chassis. Please include the outcome of the above steps.
