NTI SERIMUX SERIES SSH CONSOLE SWITCH
INTRODUCTION
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 sec urity o f Secure Shell v2 with unlimited access to remote network management. The SERIMUX-S-x allows links (or connections) between multiple pairs of RS232 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, 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. connections can be made to the same host port.
The SERIMUX supports two operator levels: user and administrator. Users may login and connect to serial devices attached at host ports. The administrator and users with administrative privileges can see and/or modify various port or user parameters in addition to connecting to serial devices attached at host ports.
Option:
• Dual AC Power Option- includes a second power connector for a secondary AC power supply cable- to order, add a
“DP” to the part number (i.e. SERIMUX-S-xDP)
• DC Power Option- SERIMUX designed for connection of 36-72VDC (48VDC nominal) for use in a Telecom
environment- to order add “-48V” to the part number (i.e. SERIMUX-S-x-48V)
• Dual DC Power Option- includes a second terminal block power connection for a secondary 48VDC power supply- to
order add a “-48VDP” to the part number (i.e. SERIMUX-S-x-48VDP)
Up to five (5) concurrent

NTI SERIMUX SERIES SSH CONSOLE SWITCH
INSTALLATION
This NTI switch was designed to be mounted to a rack or to set on a desktop. It includes rack mount ears to make attachment to a rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.
To Mount to a Rack
1. Attach the ears to the switch using the #6-32x3/16" flat Phillips-head screws (6) provided as shown in the illustration below. The holes in the ears should line up with pre-threaded holes in the sides of the NTI switch. Tighten the screws securely.
Figure 1- Secure rack mount ears to switch
2. Install 4 cage nuts (supplied) to the rack in locations that line up with the holes in the mounting ear on the NTI switch.
3. Secure the NTI switch to the rack using four #10-32X3/4” screws (supplied). Each screw should be of sufficient length to go completely through the NTI mounting ear, rack frame and fully engage all threads in the cage nut. Be sure to tighten all mounting screws securely.
4. Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.
