SUMMARY: RSC Console question

Original Question:

Is it possible to have console I/O directed to the rsc-console AND to
ttya?  I love the RSC for remote management, however, I'm not
comfortable with disabling serial access in the event of a network
outage, etc.  The output-device and input-device parameters will accept
multiple variables, however, I was under the impression that console
access was an all or nothing type of thing.

Note:  The RSC's I am working with are the Sun Fire 280, 480, and 880
series NOT the E250 series.

Solution:

Using a Netra RJ45 to RJ45 console cable with a RJ45 to DB9 adapter, I
was able to gain access to the RSC through the serial port ON THE RSC.
This will allow my Data Center engineers to get on box using a Wintel
laptop in the event of a network failure that prohibits access to the
RSC via the Ethernet port.  The only caveat to this solution is if the
RSC itself has failed and the serial port itself in unresponsive.

Note: The RJ45 - DB9 converter I used was straight through.

FYI.. I get my Netra console cables from BayTech (my console server
vendor).  The BayTech part # is RJ08X-007-07.  I believe this cable is
nothing more than a Cisco console cable.

	If I remember right from when I had RSC systems, there is a
serial port on the RSC, in case you want to attach a modem, i.e., for
use in a client's LAN where you don't have access.  The purpose of the
RSC is to provide full remote console, where you can power down the host
machine and power it back up again, just as if you were standing in
front of the rack, which you can't do from a modem attached to ttya.
