Remote Power Management Units – Faster and More Economical than a Service Call

Wednesday, August 31st, 2011

When a critical network element at an offsite data center or remote network equipment site suddenly locks up and disrupts communication, the last thing you want to do is send a tech team out to the site to deal with the troublesome device in person. Sure, a service call is often the most obvious solution, but service calls are also time consuming and expensive. A much better solution for dealing with unresponsive devices at distant network equipment sites, is to install a remote power management unit at the site, that allows you to reboot locked up devices without the expense of a service call or the time that is wasted while waiting for the service team to travel to that offsite data center or remote equipment rack.

Why Are Security and Authentication So Important for Console Access Servers?

Wednesday, August 17th, 2011

A console access server provides network administrators with a convenient “back door” for out-of-band access to console port command functions on remote network elements. Although this function can prove extremely valuable when troubleshooting communication problems at remote sites, it’s also a good idea to keep in mind that without proper security and authentication features, a console access server can also present a potential weak spot in your network security.

Callback Security – An Important Feature for Modem-Based Console Server Applications

Friday, May 13th, 2011

When managing network devices at extremely remote installation sites, it’s not always possible to establish a connection with a console server unit via network cable. In cases like this, network administrators often rely on an old fashioned dial-up modem connection in order to communicate with the console server and other devices at the remote site. Although dial-up is obviously slower than a network connection, it serves well for administrators who need to check status or perform troubleshooting functions at these remote sites.

Secure Console Port Access via Out of Band AND Dial-Up

Wednesday, October 27th, 2010

Sometimes, it’s nice to have as many alternatives as possible; especially when you’re talking about a console server. When your network is down, a console server with an out of band management solution often provides the only way to access command functions on remote network devices, without a long, expensive trip to a remote network facility. With that in mind, it’s good to know that WTI console server products provide two different means for accessing command functions on remote network devices: via out of band network, or via dial-up modem.
