+1 on conserver. I think the greatest asset of conserver is, that it
harmonises your OOB network into single interface. You can have
different generation of OOB kit from different vendors with different
level of functionality. Yet you get all the important functions from
all of them.

a) multiplexing of console access (very nice if person has went to
lunch and you really need to access that console now)
b) persistent logging of all console output (might be that crucial
little detail which will allow vendor to solve your service request)

Before I learned about conserver I wanted to use something like
cyclades (or what ever it's name is now after two acquisitions) or
opengear, just to get those two crucial features I need. But after
conserver, I greatly prefer just using Cisco console ports, as then I
can use device which is well known and already toolised by the
organisation, and will offer all the WAN access options I need, with
encryption when needed. But not having multiplexing and persistent
logging earlier was deal-breaker, now it's immaterial.
Sure opengear and cyclades probably can do few WAN options and
probably some encryption, but operationally that would be chore to me,
compared to rocking platform I already know.

Big hand to who ever caused JNPR to add ISIS/CLNS to SRX (I think
DTAG?),  I wish someone would get JNPR to add async ports to SRX too,
so that I'd have other option than CSCO for OOB. Big thanks to CSCO
for still bringing async serial ports to CISCO4321, I know the demand
must be rather small.
