Checklist for Power Up

You are ready to power up the Cisco router if the following steps are completed:

The chassis is securely mounted.

Power and interface cables are connected.

Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop bit, and no parity.

You have selected passwords for access control.

You have determined the IP addresses for the Ethernet and serial interfaces.

Front Panel Indicators

The meanings of the LED indicators for Cisco 3725 and Cisco 3745 routers are described in the following sections. For more detailed information about the LEDs, see Appendix A, “Troubleshooting.”

Cisco 3725 LED Indicators

The following indicator LEDs on the front of the chassis provide power, activity, and status information:

Power (green)—LED is on when power is on

SYS/RPS (green):

Rapid blinking (200 ms)—System is booting

Slow blinking (1 s)—Redundant power supply (RPS) failure

Continuous on—System OK

Activity (green)—Blinks during system activity, such as interrupts and packet transfers
