Your Remote Power Switch Might Be Able to Do More than You Imagined

Friday, November 18th, 2011

When a vital network device at an off-site data center suddenly locks up and refuses to communicate, most network administrators rely on a remote power switch to reboot the uncooperative network device and restore communication without the need for a service call. This capability can prove extremely valuable in any network application that includes communication with important network elements located in remote equipment racks. But in addition to allowing administrators to reboot remote network devices, a remote power switch can also offer other capabilities that help to minimize network downtime and simplify the process of managing off-site network equipment.


Remote Power Management Made Simple

Tuesday, July 19th, 2011

When a network element, such as a router or firewall, at a remote equipment rack suddenly decides to take an unscheduled vacation, often all it takes to get that router or firewall up and running again is a simple power reboot. “Simple” might not exactly be the right word to use here though; a power reboot is only “simple” if the router or firewall is located within easy reach, across the hall or in the building next door. If that troublesome router or firewall is located at an off-site data center or in a remote equipment rack several states away, then even a “simple” power reboot suddenly becomes a bit of a challenge … unless that distant equipment site includes a remote power management solution.


Picking the Right Remote Power Control Switch Product for Your Application

A remote control power switch installed at an offsite data center or remote equipment rack can provide network administrators with a handy assortment of power control and power management capabilities that simplify the task of managing remote network elements and keeping track of conditions at remote network equipment sites. Although the most common use for a remote control power switch is to reboot unresponsive devices, a full-featured remote control power switch can also perform a number of other handy functions, such as scheduling power up and power down times for remote devices, performing power load-shedding and recovery during peak power consumption times and tracking rack temperature and current consumption.


Why is a Ping Response Monitor an Important Element for Console Server Management Solutions?

Wednesday, March 30th, 2011

In most out of band management applications, a console server management unit is employed to provide remote access to console ports on critical network devices. This provides network administrators with a valuable tool for invoking diagnostic, troubleshooting and configuration commands at remote devices without actually traveling to the remote equipment site in person. Out of band access enables administrators to respond more quickly to network emergencies and reduces network downtime, but if the console server management product also includes a ping response monitor (or ping-no-answer alarm) then the console server unit can also automatically alert administrators whenever a target device fails to respond to ping commands.


How Can a Console Server Detect a Network Problem Before Users Complain?

A well-designed console server should be able to do more than merely provide out of band communication with remote network devices; it should also be able to monitor remote devices and inform network administrators when potentially troubling conditions are detected. One of the most important tasks that a console server can perform, is to monitor ping response by remote network devices, in order to allow network administrators to know immediately when a device ceases to respond.


Is Your Terminal Switch Safe from Hackers Looking for IP Addresses?

Thursday, October 14th, 2010

When it comes to terminal switch products and other out of band management tools, ping command response sometimes creates an overlooked security hole. In many situations, hackers who are interested in gaining access to important network control functions can discover IP addresses for sensitive network devices by randomly pinging a series of IP numbers until they find an address that responds. Once a device responds, the hacker then knows the IP address of the unit, providing an initial foothold that could be used to eventually gain access to secure devices.


How do You Find Out About a Crashed Network Device Before Your Users Start to Complain?

Saturday, July 3rd, 2010

Sometimes, when a rack mount network device fails or crashes, network administrators won’t know about the failure until a user complains that a service in unavailable. Wouldn’t it be handy if you could know about a crashed device before the user complaints start to roll in? Realistically, there are only two ways to accomplish this: 1) Sit beside your equipment rack, 24/7 watching to see if a device fails, or 2) Use a console server with a Ping-No-Answer alarm or ping-response-failure alarm to watch your equipment for you!
