should glow blue after power button pressed. Then the busy LED starts blinking orange
for around 60 seconds. After that, the busy LED goes off. If the busy LED keeps blinking

need to be repaired.

through a HUB or a router.
2-4. Check if the Admin login webpage shows up and works fine. Then check if the system
status is normal and HDD power LED works fine. In case the results are positive, it
means the N2100 system is OK. Otherwise, the N2100 is damaged.
