Step 3
Turn ON the power switch. The power LED on the front panel of the router should go on.)
Step 4 Verify that the OK LED on the right side of the front panel goes on after a few seconds’
delay when booting. If you have problems, see the next section, “Troubleshooting,” and
the section “Obtaining Service and Support” later in this document.
Troubleshooting
Check the following items to help isolate problems with the power supply installation:
• With the power switch on, is the power LED on the front panel on?
— If not, check the AC or DC input, AC or DC source, router circuit breaker, and the power
supply cable (AC) or power supply wiring (DC).
— Check the power supply connection to the motherboard.
— If the power LED is still off, the problem might be a power supply failure.
• Does the router shut down after being on a short time?
— Check the fans. If the fans are not working, the router will overheat and shut itself down.
— If the fans are not working, check the power supply connections to the fans.
— Ensure that the chassis intake and exhaust vents are clear.
— Check the environmental site requirements in your router installation and configuration
guide.
