Cisco - Hardware Troubleshooting for Cisco 1700 Series Routers

Symptom

No LEDs are on after powering on the router

LEDs are on after powering on the router, but there is

nothing on the console

Router displays the System Bootstrap version and hangs

at that point, or falls into a booting loop, repeating the

same information over and over:

System Bootstrap, Version 11.1(7)AX (7)AX],

EARLY DEPLOYMENT RELEASE SOFTWARE (fc2)

Recommended Action

Verify that the power supply is plugged in firmly. If

that does not resolve the issue, replace the power

supply. If the problem persists, replace the router.

Follow these steps to connect the PC or terminal to

the router:

1. Verify that your PC or terminal emulation

software is configured to communicate with

the switch using hardware flow control.

2. Configure the baud rate and character format

of the PC or terminal to match these console

port default characteristics: 9600 baud, 8 data

bits, 1 stop bit, No parity.

3. Using the supplied rollover cable, insert the

RJ-45 connector into the console port.

4. Attach the supplied RJ-45-to-DB-9 female

DTE adapter to a PC, or attach an appropriate

adapter to the terminal.

5. Insert the other end of the supplied rollover

cable in the attached adapter.

6. Run the terminal emulation program if you are

using a PC or a terminal.

If that doesn't help, verify that the equipment used

for connecting to the console is operating properly.

You can do this by connecting to a known good

router to check your console equipment. If the

equipment is successfully tested, but the problem

remains, replace the router.

The memory may not be well-seated. First, try to

reseat (remove and then re-insert) the Dynamic RAM

(DRAM) single inline memory module (SIMM)

memory. If the router still does not boot, replace the

router.

You can find information on the location of the

DRAM SIMMs in the

Cisco 1700 Series Routers

Documentation.

Set the configuration register to 0x2102 and reload

the router:

rommon 1 > confreg 0x2102
