[c-nsp] IP/VC 3526 serial port is not showing anything

[luismi]

Hi all,

We take a Cisco IP/VC 3526 from one of our racks.
We tried to access to it over the serial port with 9600 8N1 -as the
documentation says- and it didn't work.
We also have an alarm in the from but we were not able to find the
relation with it in the documentation.

As far as we read the product is EoL/EoS but it will have support until
2011 or 2012, so what is the natural alternative to replace it?

Any comment is welcome, not neccesary should be Cisco.
