Issues with Pix not booting

I have a Pix firewall that when you try to boot it up beeps 1 time then 3 consecutive beeps twice then a final beep. I can not even console into the device. Any ideas on what this is?

Re: Issues with Pix not booting

Connect up with console cable and then power on to see whatever appears on the screen (if anything at all).

I would check that the memory is seated properly inside the unit.



Email direct if you need any further assistance.


Re: Issues with Pix not booting


Thank you for your response. Turns out that it was amemory chip. However, now I get three beeps, the floppy light stays lit and nothing is showing when I attach via the console. Any suggestions?

Thank you

Re: Issues with Pix not booting

The only next steps is to use the following where the problem might lie:

PIX Boot Sequence

This section describes the steps that a PIX completes when it is powered on. Use it to verify that the basic PIX

hardware components are working correctly to ensure minimal operation.

For a PIX that is is functioning normally, the following sequence of events takes place when the PIX is

powered on. Follow the steps in the order listed, using the suggested solutions listed below to help you resolve

any issues.

Fan starts operating. 1.

Console messages start appearing. 2.

Power LED is lit. 3.

Console prompt is seen. 4.

ACT and/or Network LED on Network Interface Card(s) (NICs) is lit. 5.

You may also want to verify the following:

Does the disk drive work (for earlier PIX models with disk drives)? ·

Does the drive light come on (for earlier PIX models with disk drives)? ·

Is the problem observed with no or light traffic through the PIX? ·

Suggested Solution if Fan Does Not Start Operating

Check the power source and the power switch on the PIX. ·

Try changing power outlets. ·

If you are using an Uninterrupted Power Supply (UPS), verify whether or not the PIX works if it is

not connected to a UPS.


Try another device in the suspect outlet. ·

Suggested Solution if Console Messages Do Not Appear

Is the console cable the correct one? To make sure it's the correct one, check whether or not the

console cable and the PC serial port work on another device, such as a Cisco IOS® router. If another

device is not available, compare the ends of the cable side by side. The cable should be rolled, with

the wire colors exactly reversed. If necessary, also check whether or not the console port works with a

different PC.


Apply the correct terminal emulator settings for console connections. ·

The memory in the PIX might not be seated properly. If this is the case, the fan functions but the PIX

itself does not. Verify that the memory is seated properly.


Check whether or not the PIX finds the flash and RAM at this stage. See the sample output for PIX

under normal operation.


If you still have issues after checking the above, you might have a faulty unit.

Suggested Solution if Power LED Is Not Lit.

Check the power source. If the fan is operating but the LED is not lit, it could be an LED issue. ·

Suggested Solution if ACT and/or Network LED on NIC Card(s) Is Not Lit.

Check whether or not the network cable is connected. ·


Make sure a straight through cable is used for hub or switch connection; otherwise a crossover cable

is used.

Try changing cables. ·

Try reseating/swapping the NICs. ·

If there are more than two NICs, does the PIX boot without problem when the third NIC is removed

or if the NICs are swapped?



So essentially, as we are talking about a 520 here, support is minimal for them - is there enough memory? Is unit secondhand and are you sure of the IOS version installed? Version6 won't use the floppy drive to boot but needs min 16mb memory to do so.·

hope this gives yu a little more help
