Does Your Out of Band Management Application Include both RJ45 and DB9 Format Devices?

Tuesday, September 6th, 2011

It’s pretty safe to say that most network administrators are already familiar with the communication capabilities that are provided by an out of band management solution. An effective out of band management solution provides administrators with a powerful tool for communicating with remote network devices when normal network communication is down or unavailable. In spite of this though, sometimes a very simple thing, such as cabling format, can stand in the way of implementation of an out of band management solution, even when the value of out of band communication is obvious.


Remote Power Units Provide a Quick Way to Deal with Network Emergencies

Tuesday, August 2nd, 2011

When a critical network element, located in an off-site equipment rack malfunctions and disrupts network communication, it’s often a race against time to get the malfunctioning device back up and running again and restore network communication before the complaints from anxious network users start rolling in. If the troublesome network device was located nearby, it would be a snap to fix the problem; in many cases, all it takes to get a malfunctioning device on its feet again is a simple power reboot. But when the device that’s causing the network outage is located miles away from your office in a remote data center or isolated network equipment rack, even something as simple as a power reboot suddenly becomes a big problem.


Power Redundancy Ensures Remote Console Server Access When You Need It the Most

Friday, July 22nd, 2011

When malfunctioning network equipment at a remote equipment rack brings network communication to a halt, a remote console server can often provide a secure, reliable means to access console port command functions on the afflicted network element in order to restore network communication without an expensive, time-consuming service call to the remote equipment rack. Given the powerful remote diagnostic and troubleshooting capabilities provided by a remote console server, it’s easy to see that when problems arise at a remote network equipment rack, it’s absolutely vital that the remote console server is ready and able to help support personnel to take care of the problem, and that’s why it’s also important that the remote console server includes power redundancy and power fallback capabilities.


What are the Advantages of a Serial Switch with Break Command Blocking Capabilities?

Thursday, June 2nd, 2011

In addition to providing a solution for out of band management applications, serial switches are often used to provide a means for communication between various devices in a remote equipment rack. Often, two rack mount devices are connected to RS232 serial ports on the serial switch and then the serial switch is configured to create a connection between the two devices. This provides a convenient means to allow switching to back-up devices in the event that one of the connected serial devices malfunctions, but it can also create problems for devices such as Sun servers that respond to break commands by initiating a reboot cycle. One simple way to eliminate this problem is to choose a serial switch that supports break command blocking.


Why is a Stronge Warranty Such an Imporant Feature for Serial Switch Products?

Thursday, May 19th, 2011

When selecting a serial switch for an out of band management application, there are many different features that network administrators typically look for. Some administrators need a serial switch with more alarm and notification features, other administrators are looking for a serial switch with plenty of security features and still other administrators are looking for a serial switch with data buffering capabilities. But there’s one important feature that should be of interest to all network administrators who need the out of band access capabilities provided by a serial switch; a strong, long-term warranty.


A Server Console Switch with a Power Cycle Alarm Helps to Track Power Conditions at Remote Network Sites

Friday, April 22nd, 2011

The one thing that all server console switch products have in common, is that they provide out of band access to console port command functions on important network elements when your main network is unavailable. But in addition to out of band management applications, a server console switch can also perform other vital functions that can prove very useful to network administrators who manage remote network installation sites. For example, if the server console switch includes a power cycle alarm, this helps administrators to know when power supplies at remote equipment sites become unreliable and might be on the verge of failure.


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

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.


Console Access Servers with SNMP Compatibility Simplify Remote Network Management

Tuesday, March 15th, 2011

An out of band management solution that includes a console access server allows network administrators to access console port command functions on remote network elements, monitor critical events and environmental conditions at remote sites, and establish outbound SSH connections to other devices at the remote site. If the console access server also supports SNMP control, monitoring and configuration, then this provides network administrators with even more vital tools to simplify the management of remote network equipment sites.


Why is Event Logging an Important Factor in Console Server Management?

Wednesday, March 2nd, 2011

In addition to providing out of band access to console port command functions on remote network elements, a console server management unit can also enable network administrators to be better informed about events and environmental conditions at remote network equipment sites. A console server management unit can monitor rack temperatures, power conditions, communication status and user activity at remote sites, and log and time stamp data for later review.


The Temperature Alarm – A Vital Component for Any Console Access Server

Tuesday, February 15th, 2011

When managing a remote network equipment site, there are many different factors that a network administrator needs to be aware of. In addition to monitoring events such as power supply abnormalities and device failure, there are also a number of environmental factors that must be closely watched in order to ensure network reliability. The most important environmental factor is rack temperature; when a console access server ( includes the ability to monitor rack temperature, this drastically simplifies the task of remote management, by providing administrators with assurance that remote devices are not overheating or being subjected to excessive cold.
