3660- rebooting

Unanswered Question
Dec 6th, 2009


One of our customers having a 3660(32Mb RAM) switch & upgraded their IOS  as a solution for the  switch hanging problem, by them selves.In order to upgrade IOS they had to upgrade RAM to 64Mb.Unfortunately they have installed 64Mb pc memory by mistake & the switch is keep rebooting now.So we have ordered proper cisco 64Mb RAM & installed.But the problem is still existing.

What do you think is the problem.Is the system board has burnt as a result of th wrong memory(PC memory) installed?

I have this problem too.

first of all a C3660 is a router and not a switch.

Secondly from the attached sh ver it looks like it has 128 MB of ram

>> Cisco 3660 (R527x) processor (revision 1.0) with 120832K/10240K bytes of memory.

Are you sure that the other memory chip has been removed?

Hope to help

Hi ,

Thx for the reply.

It is sure that OLD memory(pc memory) has been removed.
