Chapter 4 Connecting Fast Ethernet-PRI Network Modules Fast Ethernet-PRI Module LEDs Step 6 Step 7 Step 8 Step 9 Align the network module with the guides in the chassis and slide it gently into the slot. Push the module into place until you feel its edge connector mate securely with the connector on the motherboard. Fasten the module captive mounting screws into the holes in the chassis, using the Phillips or flat-blade screwdriver. 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 Fast Ethernet-PRI Module LEDs All network modules have an enable (EN) LED. This LED indicates that the module has passed its self-tests and is available to the router. All Fast Ethernet-PRI modules have four LEDS for the Fast Ethernet port, and four additional LEDs for each PRI port. Figure 4-18 shows LEDs for the 1-port Fast Ethernet 2-port channelized E1/ISDN PRI balanced (120-ohm) network module as an example.
