16 CHAPTER 1: INTRODUCING THE ROUTER Rear Panel 5 Cable/DSL Status LED Green (100 Mbps link) / yellow (10 Mbps link) If the LED is on, the link between the Router and the cable or DSL modem is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, the modem is switched off or there is a problem (refer to Chapter 6 "Troubleshooting"). The rear panel (Figure 4) of the Router contains four LAN ports, one Ethernet Cable/DSL port, a power adapter OK LED, and a power adapter socket.

CAUTION: Do not force the antennae beyond their mechanical stops. Rotating the antennae further may cause damage. 7 Power Adapter Socket Only use the power adapter supplied with this Router.
