Cisco 2811 Bad RAM issue

[jainamdhulla]

1 PVDM2 64 was already inserted but after inserting another PVDM2 64 the router Cisco 2811 was not booting IOS & router was going in ROMMON mode. While executing  # dir flash: in ROMMON mode it was showing bad RAM.

Just want to know that is RAM gone faulty because of another PVDM2 64 insertion?

Or inserting two PVDM2 64 can make RAM faulty?

Are this 2 PVDM compatible with this router?

Hi,

Could be the RAM was damaged by static during installation of PVDM. Did you use an ESD-preventive wrist strap when installing the PVDM?

What happens when you remove the new PVDM?

Thanks
