If the router was previously running, reinstall the network interface cables and turn on power to the router. The following warning applies to routers that use a DC power supply: Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. Statement 8 Digital Modem Module LEDs All network modules have an enable (EN) LED. (See Figure 9-9.) This LED indicates that the module has passed its self-tests and is available to the router. Digital modem modules have five additional LEDs, one for each MICA module bank. The LEDs blink during initialization. After the enable LED comes on, the MICA module LEDs indicate that the corresponding MICA module is functioning. If a MICA module fails its diagnostics, or if no MICA module is installed in a position, its LED remains off.
