THE RSM Series remote site managers from Interworld Electronics provide in-band and out-of-band access to RS232 console ports and maintenance ports on UNIX servers, routers and any other network element equipped with a serial console port.
System administrators can access the RSM via TCP/IP, using SSH or Telnet, or out-of-band via the internal modem or the local terminal port.
The RSM features two separate command interfaces; a convenient, user-friendly secure web browser interface, and a simple command driven text interface.
The RSM Series provides 8 or 16 RS232 serial ports that can be individually accessed by number, name, or group. The RSM also allows direct connections using TCP port assignments.
Each port can be separately configured using simple menu driven commands to set the port password, data rates, flow control, and other operating parameters.
The full matrix capability allows users to easily connect any two ports on the switch, even when the ports are using different communications settings.
Ports can also be connected or disconnected by a third party with supervisor rights, and system managers can swap various RS232 devices between ports at a remote location.
Secure Shell (SSHv2) encryption and address-specific IP security masks prevent unauthorised access to command and configuration functions. The RSM also provides two different levels of user security; the Supervisor level and the Non-Supervisor level.
The Supervisor level, which is intended for use by system managers and other administrators, provides complete access to all RSM port connection/disconnection functions, operating features and configuration menus, and also allows access to any port on the switch.
The Non-Supervisor level is ideal for co-location applications, since users are only permitted to view status and connect to the ports allowed by their user name and password.
"Buffer Mode" allows individual ports to capture and store incoming data, such as error and status messages received from attached console ports.
This "snapshot" of the last data received is stored in memory, and can be viewed, saved or erased by the system operator at any time.
Console messages can be stored in the RSM port buffers, and sent to a remote location via SYSLOG, or an SNMP message can be generated to alert administrators when new console messages are received.
The 8-port RSM-8 and 16-port RSM-16 are powered by 240V ac while the RSM-16DC operates from a –48V dc supply.
