Sorry, I never had an ISR4351 in my hand. If anyone has a repaired previously affected model, please let us know. ... View more

The ohm reading is across the added resistor. Yes, I worked on ASA5508 as well and applied the fix successfully. ... View more

May I talk to an Cisco Account Manager to raise that issue? ... View more

Just a note:   According to Cisco, NAT on Dialer is not documented and thus unsupported   My experience is that is works well on IOS-XE 3.xx series but once you upgrade to 16.x.x (Denali etc..) it has severe problems. All TCP, UDP or ICMP traffic going though Dialer-NAT might stop working without notice   That whole situation is very bad.   All cutomers coming from older ISR G2 series with xDSL are required to use NAT on Dialer. There is no other option.   So what are your options: - Cisco denies support for NAT on Dialer on IOS-XE (ISR 4k platforms) - There is no alternative - Going back to older ISR G2?   If someone has a Cisco Account Manager, please let them know about that issue.   NAT on Dialer is essential in many situations and in particular for sales when replacing old ISR G2 units.   ...

I can't tell you exactly. I always ask my Cisco sales rep and he tells me the correct product number.   Usually SmartNet 8x5xNBD SW+HW service is sufficient. But I have unfortunately no informations about the correct part number of the service.   Anyhow: Having SmartNet allows you not only to RMA your unit but you can always get the newest firmware, IOS, ASDM and FirePOWER Software for your Firewall. It is really worth the cost.     ... View more

Good choice :)   You can check if the S/N is still unclaimed in the "Cisco Device Coverage Checker" ... View more

Yes, they do. Period. BTW: This is what Ciscos "clock signal team" is telling in their email if the unit S/N is not eligible for free replacement. ... View more

Please let it be.   Cisco will not tell you ANYTHING.   You can buy SmartNet and let them replace the unit. It's simple as that.   You are not supposed to fix your own equipment and Cisco will certainly not assist. ... View more

Paul,    if you can get the replacement BGA CPU, if you have the appropriate soldering tools (hot air, pre-heat plate etc.), well, you can try to do it and replace the CPU.   Chances are low to get all balls properly soldered.   Honestly: Buy a new ASA or send the non-working unit to Cisco for exchange.   Hint: If your ASA has no service contract, buy a 1 year contract and let Cisco exchange the unit after 30 days.   Best regards, Bernhard ...

If the firewall is already broken, there is no chance to fix it.   The CPU is physically damaged internally and cannot be fixed.   Only when the firewall is still working, applying the fix will prevent the CPU to get bad.   Sorry, the only chance you might have is to send the unit back to Cisco for replacement.   ...

According to my findings, no components need to be "pulled" or removed. All devices have only a resistor added (different values depending on model). ... View more

Hello Paul,   to which pictures are you referring to?   Cheers, Bernhard ... View more

Note: That fix is one of the easiest but you need some magnification to do it well. On a scale from 1 (hard) to 10 (easy), ASA5506 repair scores a personal 7. ISR4321: 6 ISR4331: 5 (many screws, big board) ASA5508 & AA5506 (actually the same board): 3 small and fragile pads As always practice good ESD protection, care and apply thermal paste when putting all together. ...

Here is what all of you have been waiting for:   Pictures of repaired ASA5506   Resistor is 150 Ohms, 0604 or 0402 SMD case.   Attached you can find an overview (spot the fix) and two microscopic (43x magnification) pictures, one of them at an angle to better see the solder joints.   That fix looks reasonable, much flux residue on the bottom but quite well done. I will resolder them anyways and put eventually some liquid soldermask to protect the fix.   Feedback welcome :)   ... View more
