Console Server & RIM Gateway User Manual
If you need other plug-ins to be loaded into the IM42xx firmware:

If the plug-in in a Perl script, it must be rewritten as the console server does not support Perl at this point.
However, if you do require Perl support, please make a feature request to support@opengear.com

Individual compiled programs may be generated using gcc for ARM. Again contact support@opengear.com for
details
10.4.4 Number of supported devices
Ultimately the number of devices that can be supported by any particular console server is a function of the number of
checks being made, and how often they are performed. Access method will also play a part. The table below shows the
performance of three of the
console server models (1/2 port, 8 port and 16/48 port) tabulating:
Time No encryption 3DES SSH tunnel
NSCA for single check ~ ½ second ~ ½ second ~ ½ second
NSCA for 100 sequential checks 100 seconds 100 seconds 100 seconds
NSCA for 10 sequential checks, batched upload 1 ½ seconds 2 seconds 1 second
NSCA for 100 sequential checks, batched upload 7 seconds 11 seconds 6 seconds
No encryption SSL no encryption - tunneled over
existing SSH session
