Remote Out of Band Access for DC Powered Network Equipment

Wednesday, April 11th, 2012

The task of managing network devices can often be a real pain in the neck … especially if the network devices in question are located in a remote equipment rack rather than in the room next door. When vital network elements are located at distant, offsite facilities, network administrators are presented with an entirely different set of challenges than would normally be seen if those same devices were located within arm’s reach.

A Console Switch with Outbound SSH and Outbound Telnet Capabilities

Wednesday, January 18th, 2012

When your primary means of communication with remote network equipment fails, it’s always good to have other options for contacting various devices in the remote network equipment rack. As long as you can communicate with the devices in the remote equipment rack, then you still have a chance of solving the communication problem without an expensive service call to the remote rack. Although a console switch provides the basis of an excellent out of band management solution, it can also be helpful if the console switch provides additional communication options that can be employed to communicate with other devices in the remote network equipment rack when your primary network is down or unavailable.

Keeping Better Track of Conditions at Remote Network Equipment Sites

Monday, December 26th, 2011

When managing network devices located at off-site data centers or in remote equipment cabinets, it isn’t always easy to tell when power to the remote network equipment has been interrupted and restored. Sure, you could always wait for users to complain that a server or router at the remote site didn’t recover correctly, but in a busy corporate network environment a network administrator often needs to be more proactive when it comes to dealing with power interruptions and disrupted network service. It’s pretty easy to tell when power at the remote network equipment site is out completely, but how does one recognize a situation where power momentarily blinks off and then back on again?

Outbound SSH/Telnet Provides Another Alternative for Console Switch Communication with Remote Network Devices

Wednesday, November 23rd, 2011

Most network administrators are already familiar with the concept of using a console switch to create an out of band connection to network elements at a remote equipment site, but it might come as a surprise to some that a console switch can also be used to provide out of band access to a local network at a remote equipment site. When network equipment cabinets are located so far off the beaten track that direct network communication with the cabinet is not possible, a console switch that supports outbound SSH/Telnet can be employed to allow users to access a local network at the remote site via dial-up connection, and then communicate with any device on the local network at the remote site.

A Serial Switch that Supports Network Time Protocol Provides Exact Synchronization

Thursday, April 21st, 2011

In many network applications, the ability to synchronize time settings across a variety of different network devices is of utmost importance. This is especially true in applications where data is collected from multiple network devices, and when time stamped log records are generated to record significant network events. In cases like this, a serial switch that supports network time protocol (or NTP) can prove to be a very valuable asset.

A Console Switch that Provides Convenience AND Security

Thursday, November 11th, 2010

In any large network application, a console switch is an extremely useful tool for remote management of devices at far away network installations and equipment sites. Console switch products eliminate or reduce the need for expensive service calls to remote sites, by providing an avenue for out of band management and allowing network administrators to monitor environmental and operating conditions without actually traveling to each network site in person.

A Serial Console Switch with Alarm Notification via SNMP Trap

Thursday, October 21st, 2010

A serial console switch performs many different duties in a network application; it allows out of band access to network devices when your main network is down, it provides a backdoor to configuration and diagnosis functions without interfering with regular network communication, and it can also monitor network devices for potentially harmful environmental conditions and suspicious network events. Alarm and monitoring functions are an extremely useful capability, but only when the console switch includes a means to effectively notify network administrators when a problem is detected.

A Console Switch that Can Let You Know When a Power Supply Dies

Wednesday, October 13th, 2010

One of the major challenges facing all network administrators, is the need to develop a system which will allows them to know immediately when network elements crash and cease to function. If power is lost at a remote network equipment site, how can the network administrator know about the power outage before it takes down the network and users start to complain? The most popular solution to this dilemma, is to make certain that the network includes a secondary, maintenance network and a console switch with appropriate environmental alarms and notification features.

How Do You Communicate with a Network Element When the Network is Down?

Wednesday, September 22nd, 2010

Given enough time, just about any computer network will eventually crash; that’s just the nature of networks. Ideally, your network shouldn’t crash on a regular basis, but when it does go down, how do you communicate with remote network elements in order to get the network up and running again? In cases like this, obviously, you can’t communicate with a problematic, router, server or switch via a normal network connection … but that still doesn’t mean that communication with a remote network device is impossible.

How Can a Console Switch Capture Error Messages from Network Devices?

Wednesday, September 8th, 2010

Most savvy network administrators know that a console switch can be used to provide remote command access to console ports on network elements such as routers, servers and switches. This provides a valuable tool for remote diagnosis and troubleshooting of network devices, but an advanced console switch can also do a lot more than just provide remote command access. For example, a console switch can also be used to collect error messages and alarm messages that network elements transmit via their console ports.
