Console Server Access
The SC5-4xIP unit supports Console Server access to multiple devices (such
as dedicated specialist servers, Ethernet switches, IP routers, etc.) that are
connected to it via their RS-232 serial ports. Authorised global users can switch
to any of the connected devices and access them using either the Telnet or SSH
(Secure SHell) protocols.
Global connections are limited to a total of four concurrent sessions and these
can be all VNC sessions, all Console Server connections or a mixture of both.
Global users logon to Console Server connections using the same username and
password details as created for them for VNC global connections.
Linking console devices
Special Console CAMs are used to connect each console device to the SC5-4xIP
unit. Each Console CAM is connected to the unit using a CATx lead as usual. On
its other side, each Console CAM has only a 9-way D-Sub female RS-232 serial
connection to link it to the server device.
The Options port on the rear of the unit can also be used as a Console Server
connection when it is configured to operate as such within the Serial Port page
of either the
local menu
or the
remote menu
.
All 16 ports of the SC5-4xIP can be used solely with Console CAMs, solely with
KVM CAMs or a mixture of the two types, as follows:
• If the entire unit is used solely for console connections then all 16 ports can
be used with Console CAMs. With the Options port also set into Console
Server mode, that provides a total of 17 possible console connections.
• If at least one KVM CAM is also used, then the maximum number of
Console CAMs that may be fitted falls slightly to a total of 13 (the Options
port is still useable as an extra console connection).
Note: If a KVM CAM is replaced by a Console CAM, the SC5-4xIP unit must be
rebooted or reset. This can be achieved either with a power cycle or remotely by
using Unit Configuration >
Advanced Unit Configuration
> Reset Unit button.
Setting serial connection parameters
The serial connection parameters are determined within the
Console
Server Configuration
page of the remote configuration menu (accessible
via VNC connection). Within that page you can apply a default set of
serial communication parameters to all ports that will be used for console
connections. Alternatively, the
Console Server Port Configuration
page allows
you to adjust each console port individually.
Within the
Console Server Configuration
page there are two key settings
which determine the base port addresses for Telnet and SSH connections into
the SC5-4xIP. These are set to 2400 and 2600 respectively and will feature in all
global links through the unit to the required console server device, as discussed
next.
If required, alter the base port
addresses for Telnet and/or SSH
