Overview

The SERIMUX® Secure SSH Console Serial Switch 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.

Operates on a hardened Linux system.
Connect up to 32 devices with different baud rates, parity, and character length. Each switch also has one RJ45 connector for a local terminal.
Eliminates the need to connect each device to an ASCII terminal or PC.
Provides out-of-band access to network devices (servers, routers, network switches, and any other network devices allowing console operation using RS232).
Connects to console serial ports using standard CAT5/5e/6 cables and cable adapters.
- Maximum cable length is 1000 feet (305 meters).
Dual Ethernet and optional dual power provide redundant connectivity and power.
USB port provides expanded logging storage, configuration export and additional functionality.
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.
Gain access to servers without interrupting service to end-users; maintain optimal up-time.

Monitor environmental conditions.
- Supports two sensors, including: temperature/humidity and water detection.
- When a sensor goes out of range of a configurable threshold, the system will notify you via email, LEDs, web page, and network management (SNMP).
Power cycle without halting SUN host computer.
- No inadvertent "break" signals are generated to cause unintentional rebooting of SUN computers.
Powerful diagnostic and event management features (data capture, notification and scripting) assist in the quick location of the source of equipment failures and minimize downtime.
Enhanced security features to protect the system - Secure Shell (SSH v2), individual port authentication, HTTPS.
Switching is simplified with programmable device names and menu-driven device selection.
- All configuration parameters are stored in non-volatile memory.
- Configuration parameters can be imported from USB Flash drive.
Firmware upgradeable "in-field" through console port, Ethernet, or an attached USB Flash drive.
1RU case is standard. Includes rack mounting kit.

SSH Console Serial Switch with Environmental Monitoring

"The SERIMUX-S-4/16/32 Secure Console Switches are used for remote console access to our network switching. Up until now, we have been required to go on-site and plug directly into the console port of the network switches in order to make configuration changes. This product allows us to remotely configure the switching as if we were sitting right there plugged directly in."

"We are using the SERIMUX® Secure Console Switch in our remote locations in order to support our facilities when there is an outage. We connect a modem into one port, and our network hardware's console port into the rest of the ports. This gives us the ability to see what is going on with our routers as well as the core switches. We are very happy with the performance of the devices. So happy, in fact, that we have committed in purchasing one for every one of our facilities. I do recommend that you purchase more ports than what you need. You never know what the future brings. We have standardized on the 16 port for our smaller facilities and the 24 port for our larger ones."
