SUMMARY: serial/console server

My original query:

> We have about 200 Sun, Compaq/DEC, IBM/AIX, etc. boxes in a server 
> room.  Currently, the serial ports are connected via an Annex box 
> to provide remote console access.  (Telnet to annex and connect to
> a port for the console.)
> I'm looking for a newer device that can do the same as above, plus
> has secure (ssh) connection to the device.  Multiple boxes to get
> 200 ports is okay.  Telco type connectors would be ideal.

Many thanks to these folks for suggestions:

 Cisco 3600 would be your best bet.. A 3660 would be good, though you
 might want to scale back to a 3640. There's a NM-32A module which is 
 32 serial ports. I know these usually come with octopus cables, 
 however you might want to check cisco's site to see if there's other

 You should be able to max out the 3660 w/ 6 of these (for 192 ports),
 or a 3640 with 3 (it takes 4 NM's, however has no onboard ethernet, so
 you'd need to save a slot for that).

 In IOS terms, you want a 'transport input ssh' for an async line (have
 your salesdroid check w/ their SE just to be sure).

 Other than this, I think your only option is the really lousy approach
 of a PC loaded out w/ multiport boards. Doing linux on a floppy or
 will make it a bit cleaner, but its pretty hokey IMHO.

Here are other suggestions (URLs) and my comments: (I have not analyzed
these well enough to figure out what is a good solution for me)
Remote access server.  Supports a whole bunch of protocols, but didn't
see SSH in there.
Runs on a Solaris box, with serial connections.  Since it is Solaris,
you can have latest SSH you like. (Soft/Hardware solution)
Seems to be KVM switches.
TS1000 and TS2000 - They are running Linux.  SSH included.
"Cisco 3640 w/ 1 Ethernet module & 3 Aysnc modules = ssh + 96 ports."
(See complete answer above, but I'm not sure how SSH is obtained)
Stallion serial ports. "You can get upto 254 ports per card last time 
I looked (several years ago). We had over 80 consoles from a linux box 
and it worked well."  (Hardware only)
Didn't see SSH, but it does have ID/Passwd and access rights per port
SCSI based serial connections for a Sun/PC/whatever. (Hardware only)
Unix Serial Port Resource page.  Has many links to everything_serial.
