  • Eliminates the need to connect each device to an ASCII terminal or PC.
  • Connect up to 32 devices with different baud rates, parity, and character length. Each switch also has one RJ45 connector for a local terminal.
  • Provides out-of-band access to network devices (servers, routers, network switches, and any other network devices allowing console operation using RS232).
  • Power cycle without halting SUN host computer.
    • No inadvertent "break" signals are generated to cause unintentional rebooting of SUN computers.
  • Dual power option creates a redundant power system protecting the console switch from any power failure issues.
  • High quality, rugged steel construction with durable powder coat finish.
  • Command Line Interface via Telnet for advanced management functions.
  • Connects to console serial ports using standard CAT5/5e/6 cables and cable adapters.
    • Maximum cable length is 100 feet (30 meters).
  • Two operator levels (administrator and user).
  • Switching is simplified with programmable device names and menu-driven device selection.
    • All configuration parameters are stored in non-volatile EEPROM.
  • Built-in data buffers save the most recent RS232 console output from each connected device, which simplifies troubleshooting failures.
  • Local commands can be directed via VT52, VT100, ANSI serial console, a PC with a terminal emulation program, or any compliant terminal.
  • Gain access to servers without interrupting service to end-users; maintain optimal up-time.
  • Manage server farms or data centers via serial ports and standard external modems or through optional Ethernet interface using Telnet or Web interface.
  • 1RU rackmount case is standard.

Application Notes

  • Dual Redundant Secure Access to Serial Ports
    Product Overview
    To gain dual redundant secure access to the serial ports of servers, begin by connecting a server to the console port of the SERIMUX-CS-xx. Then, configure a serial port on the SERIMUX-CS-xx to a user port and connect an additional server to that port. Use Secure Shell to access one of the servers connected to the internet. Then, using a terminal program such as minicom, tip or cu, access the SERIMUX-CS-xx Console Switch. Log in to the SERIMUX-CS-xx Console Switch to access any of the serial management ports of the servers as shown below.
