A Serial Switch with a Power Cycle Alarm Helps to Manage Remote Network Equipment

Thursday, March 24th, 2011

When power to a serial switch is interrupted, this usually means that power to the rest of the equipment rack has also been interrupted. When power outages occur at remote network sites, network administrators often have no way of knowing about it unless the power outage affects network communication and users complain. Although a serial switch is designed mainly for out of band communication with console ports on remote devices, it can also be useful if the serial switch can notify administrators when power to an equipment rack is temporarily lost.

Useful Features to Consider When Choosing a Serial Switch Product

Thursday, March 10th, 2011

A Serial Switch (http://www.wti.com/c-46-serial-switch.aspx) is a valuable tool for out of band management applications, but ideally it should be able to do more than provide remote access to console port command functions. In addition to providing out of band access, serial switch units should also be able to monitor conditions at remote network sites, log temperature readings and user activity, check device response to ping commands and perform other functions that simplify remote management of important network elements. In addition to these tasks, it’s also handy if the serial switch unit can broadcast data to connected devices.

A serial switch (http://www.wti.com/c-46-serial-switch.aspx) should be able to more than just provide access to console port command functions on remote network elements. Ideally, a serial switch should also be able to monitor conditions and events at remote network sites and notify network administrators when potential problems are detected. In addition, a serial switch should also be able to report its own status, network conditions and port conditions and log noteworthy events for later review.

A Serial Switch that Can Notify You When Power is Interrupted

Thursday, February 10th, 2011

Sometimes, it’s difficult for a network administrator to know exactly what’s going on at a remote network equipment site. When the power supply to a remote device is interrupted, sometimes an administrator won’t know about it until a user complains or the power loss results in a larger problem. But it doesn’t have to be that way if your remote network equipment site includes a WTI Serial Switch. WTI Serial Switch products include a convenient Power Cycle Alarm that can promptly notify administrators when power is interrupted and then restored.

A Serial Switch that Blocks Break Commands

Thursday, January 27th, 2011

In many cases, a simple break command can cause certain types of servers to immediately reboot, resulting in a interruption of user access until the reboot cycle is completed. In most cases, a break command is received from a connected device, initiating an unnecessary reboot cycle and causing a delay while the server finishes booting up. In order to prevent unrequested reboot cycles, WTI Serial Switch (http://www.wti.com/c-46-serial-switch.aspx)products include a break command blocking option which allows the console server to prevent break commands from being passed along to a connected server.

How a Serial Switch Can Provide a Local Solution for Remote Network Problems

Thursday, January 13th, 2011

Sometimes, when a remote network device crashes or ceases to respond, all work suddenly comes to a grinding halt. Users who depend on a remote server, router or firewall can’t work on important projects, and there’s nothing to do but wait until the service team travels to the remote site and gets that device back up and running again. But that’s just the way things go, right? Well, not exactly; especially not if your remote network equipment site includes a serial switch product to allow out of band management of remote network elements.

A Serial Switch Beats a Service Call

Thursday, December 30th, 2010

It’s never a good thing when a critical network element stops running; sometimes it means that you can’t access a remote network site in order to gather data or correct the problem … sometimes, the loss of a crucial device can cause a more widespread network outage. WTI Serial Switch products help network administrators to avoid this type of problem by both notifying you when a critical device fails, and providing an avenue for out of band command access to help manage devices when your primary network is down.

A Good Serial Switch is the Heart of an Out of Band Management Solution

Thursday, December 16th, 2010

When setting up a remote network equipment site, it’s absolutely vital to include an out of band management solution that allows access to console port command functions on your remote network equipment. The reason for this is simple: no matter how well your remote network application has been planned, it’s inevitable that remote network devices will eventually crash or malfunction and require some sort of tweak or push to get them running again. In most cases, a serial switch provides the “heart” of this type of out of band management solution.

Fail-Safe Power Redundancy for Out of Band Management

Monday, December 13th, 2010

A Console Server is a wonderful tool for out of band management. When remote network devices crash or lock-up, a Console Server provides an extremely convenient way too access serial port functions on remote devices in order to fix the problem. This works fine when the reason for the crash is a problem with a server or a router, but what if the crash was caused by a failure of the primary power supply?
