Troubleshooting Power Supply
For the RSR30 series routers, you may use the power indicator on the front panel and the status indicator on the power
module to decide if the power supply system is operating normally. For description of indicators, see Chapter 1. If a
fault occurs, check
If the power supply meets the requirements.
If the router power switch is in the on position.
If the power supply switch of the router is in the on position.
If the power cable is connected correctly.
Never attempt hot swapping of the power cable. If the steps above did not solve your problem, contact
your local distributor or technical support personnel.
Troubleshooting Fan
For the RSR30 series routers, you may use the Fan_Status and Fan_Power status indicators on the fan tray module to
decide if the fan tray system is operating normally. For description of indicators, see Chapter 1. If a fault occurs, check
If the fan tray is inserted tightly.
If the steps above did not solve your problem, contact your local distributor or technical support personnel.
Troubleshooting Configuration System
When the router is powered on and everything is normal, information described in Chapter 4 during the start will appear
on the terminal. If a fault occurs, nothing or illegible characters will appear.
If no information appears on the terminal display, please check
If the power system is working normally.
If the console port cable is connected correctly.
If the steps above did not solve your problem, it is likely because of wrong configuration cable or wrong terminal
parameter setting. Please check terminal parameters.
