What To Look For In A Serial Switch

A serial switch can help you communicate with your PC and other devices remotely as well as simplify communications among many devices. Depending upon the size of the box, you can connect up to 32 devices to a single console. These devices can have different baud rates, character length and parity. Furthermore, many machines have two operator levels for the administrator and the user.

Your devices can be managed through a number of means including dial-up modem connections, the Internet and a TCP/IP network. While giving you remote network management capabilities, you are protected with a Secure Shell v2 system. You will not have to connect each device to a special ASCII terminal or a PC. You can also connect to serial ports with standard CAT5/5e/6 cables of up to 1000 feet and cable adapters. Most serial switches will sustain devices with an RS232 serial port and VT terminals and has at least one RJ45 connector for local terminals.

A good serial switch should also have good redundant connectivity and power. Many provide this with dual Ethernet and optional dual power. A switch with a USB port not only augments functionality but also increases logging storage and configuration export. Furthermore, the switch should allow you to access your servers without disrupting the service to the end users so that you maintain an optimal up time. You may also be able to get a firmware upgrade through the attached USB flash drive, console port or Ethernet connection.

The console switch also needs to be user friendly. Many switches have good diagnostic and event management features such as data capture, notification and scripture that help you quickly identify and troubleshoot any equipment failures so that you minimize any down time. You may also easily monitor the environmental conditions of your switch to make sure it stays intact. Some consoles have sensors to monitor humidity, temperature and water detection. You may also be notified by email, network management, web page or other means if a sensor goes out of range of a configurable threshold. The switching itself should also be simplified with features such as programmable device names and menu-driven device selection.

Of course, you also want your serial switch to be reliable. The machine should prevent any inadvertent break signals that lead to unintentional rebooting of SUN computers. Most switches will allow you to configure the schedule by which you would like to receive alerts. You should also receive alerts when any of the monitored environmental conditions exceeds your specified range. Although you want the console to be reliable, you should also know how to take care of the machine. You need to be sure it is operated and stored in the right temperature to prevent any damage to the machine.
