Maximize Up-Time with an A/B Fallback Switch

It doesn’t matter if you’re talking about a large, multinational corporation or a small “Mom and Pop” business; these days, most businesses depend on a secure, reliable network in order to track sales, process orders and interact with customers. This means that when your network is down, your business is also “down,” because communication and the free flow of information immediately grind to a halt.

Given the importance of network communication, most businesses strive to maximize network up-time by designing redundancy measures into their network infrastructure, and an intelligent A/B Fallback Switch is often at the key to ensuring that when one network device fails, another substitute device can be quickly deployed in order to keep the network up and running.

WTI A/B Fallback Switch products allow automatic switching from primary network devices to fallback network devices, often allowing A/B switching to be performed without human intervention. Our A/B Fallback Switch products can be configured to regularly ping primary devices and then quickly switch to a back-up device in the event that the primary device ceases to respond to ping commands. If desired, the A/B Fallback Switch can also send notification via email, text message, SNMP trap or SYSLOG message to let network administrators know that a primary device has failed and that the secondary device has been deployed.

After A/B switching has occurred, the WTI A/B Fallback Switch can also continue to monitor the primary device for ping response, and then automatically switch back to the primary device when it begins responding to ping commands again. In addition to performing ping-command driven A/B switching, the WTI A/B Fallback Switch also include output contacts that can be used to initiate A/B switching when rack temperatures rise too high, when excessive invalid access attempts are detected or when the power supply is lost and then restored. These output contacts can also be used to switch on cooling devices when rack temperature rises to unacceptable levels or disable equipment when excessive invalid access attempts are detected. All switching options can also be configured to send notification to network administrators and other appropriate personnel whenever switching occurs.

An A/B Fallback Switch can help you to maximize network up-time by providing quick, automatic fallback switching when primary devices fail to respond to ping commands or when environmental conditions and events at the equipment rack trigger user-defined alarms. This helps to ensure that even when vital network devices fail, you can always quickly switch to a backup device, often before your users even notice that there was a problem in the first place. This means that your network will always be up and running and available when you need it, and helps to ensure that your network users will always have access to the communication and data sharing functions that are so important to the operation of your business.
