Overview

The SERIMUX ^® Console Switch gives IT managers the ability to cost effectively manage serial devices, including servers, switches, routers, and telecom gear. The switch can be controlled via an ASCII terminal with menu-driven integrated software, the front panel keypad, or optional Ethernet interface.

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

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.

Connecting RJ45 Port on a NTI Console Serial Switch to RJ45 Port on Digi PortServer II

Connect a RJ45 port on a NTI Console Serial Switch (SERIMUX-CS-x or SERIMUX-S-x) to a RJ45 port on the Digi PortServer II to replace terminals. Using CAT5/5e/6 cable, arrange the wires in a RJ45 plug on each end to match the pinout for the corresponding port it will be connected to.
