Rear-Panel LEDs on Cisco 3660 Routers

For an explanation of the Cisco 3660 rear-panel LEDs, see:

•SYSTEM LED (see Table A-1)

•Power LED (see Table A-7)

•Fast Ethernet connector LEDs (see Table A-8)

•PCMCIA card LEDs (see Table A-4)

•Power supply LEDs (see Table A-3)

See Figure A-6for the locations of these LEDs.

Note The system LED on the rear panel of the Cisco 3660 router has the same function as the system LED on the front panel. (See Table A-1.)

The power LED communicates the status of the Cisco 3660 mainboard.

The LED on each Cisco 3660 router power supply has the same function as the PS1 and PS2 LEDs on the Cisco 3660 router front panel. (See Table A-3.)

The PCMCIA LEDs on the Cisco 3660 router rear panel are the same as those on the Cisco 3620 and Cisco 3640 router front panels. (See Table A-4.)
