SERIMUX-S-x
SECURE SSH
CONSOLE SERIAL SWITCH
Quick Installation Guide
The NTI SERIMUX-S-x SSH Console Serial Switch (SERIMUX) is a serial port switch that delivers secure management of up to
32 serial devices via the internet, TCP/IP network, or dial-up modem connections. It combines the advanced security of Secure
Shell v2 with unlimited access to remote network management. The SERIMUX-S-x allows links (or connections) between multiple
pairs of RS-232 asynchronous serial ports. The SERIMUX-S-x (x=4,8,16,24,or 32) is available with up to 32 serial port
connections.
The main purpose of the switch is to provide secure management of several serial devices from local or remote locations (using
Ethernet or external modems). Devices include routers, DSU's, servers, switches or any other equipment allowing serial
operation using RS232 interface. Users can work locally using a VT100 or ANSI serial console or a CPU with a terminal program
(i.e. HyperTerminal)) or from remote locations via Ethernet connection (Web Interface, SSH, Telnet).
Each SERIMUX port has to be configured for serial communication (baud rate, parity, etc) within the specifications of the attached
serial device, but the configurations of the two devices linked by the SERIMUX do not need to match. Various parameters
(communication speed, hardware and/or software flow control, timeout, etc) can be selected for each SERIMUX port. Devices
may be either locally connected or connected through attached modems.
Each SERIMUX port can be configured as either a host or user port. Serial hosts (such as servers, switches etc.) are connected to
host ports, while serial user devices (such as a terminal or serial console) are connected to user ports.
Installation
1. Mount the SERIMUX to a rack using the hardware provided.
2. Connect a serial console to the port labeled "CONSOLE" on the SERIMUX using a serial cable with an RJ45 male connector
(Cat5 patch cable supplied). This will be the default administrator device.
3. Connect each additional serial user device or host device to be connected by the SERIMUX to any remaining port
(1-4/8/16/24/32) using a serial cable with an RJ45 male connector. It may be necessary to add one of the cable adapters
(supplied) detailed in Appendix C of the manual between the device port on the user device or host device and the RJ45
connector.
4. Connect the power cord.
Connect the SERIMUX to the Ethernet for remote system management using the “ETHERNET1” or “ETHERNET 2” port and
CAT5/5e/6 patch cable.
