Routerboard Troubleshooting
When I connect power to the board, it does not make a sound nor flash a LED
Please check whether the power-source choice jumpers are in correct positions. For 20..54 V DC powering to the power plug or power header, switch the JP4 and JP5 jumpers into 1-2 position. For 48V DC Power over Ethernet powering, switch the JP4 and JP5 jumpers into 2-3 position.
Also check that the JP6 jumper is in 1-2 position and that J18 and J11 power outputs are open.
When I connect power to the board, it does nothing, but all its LEDs stay on
Please check that JP1 (Reset) jumper is open.
I am experiencing uncommon behavior (instability) of RouterBOARD
First, upgrade the BIOS and check if the RouterBOARD is still unstable.
If it is, try to disable pci back-off parameter in BIOS setup.
Common practice, how to choose the pci back-off parameter value:
- Keep enabled if you are using Atheros PCMCIA cards
- Enable on newer RouterBOARD 200 boards (with 266MHz CPU clock) with Atheros MiniPCI cards in RouterBOARD 14 (4-port MiniPCI-PCI) adapter
- Disable on older RouterBOARD 200 boards (with 233MHz CPU clock) with Atheros MiniPCI cards in RouterBOARD 14 (4-port MiniPCI-PCI) adapter
- Disable it if you are using newer RouterBOARD 200 boards (with 266MHz CPU clock) with external PCI Ethernet cards.
All of these practices has been defined experimentally, so they may or may not apply to your particular case.
What to do if my CMOS settings are resetting each time I power-off my board?
First, check that the CMOS reset jumper JP3 is in the 1-2 position. If it is, then try to replace the CMOS battery. The correct battery type is CR1620 Lithium Coin.
