In applications that involve communication with remote network elements, reliable out-of-band console access can spell the difference between effective management and chaos. When normal network communication is disrupted by a crashed Ethernet switch or other device at a remote equipment installation, out-of-band access to console port command functions enables administrators to correct the problem without the expenses and delays associated with a physical service call. An intelligently deployed Console Server provides the most effective solution for out-of-band access to remote network elements when normal network communication is not available.

When a network device at a remote cell tower crashes and makes direct communication with the tower impossible, it’s absolutely vital to have a secondary, out-of-band avenue for communication in order to allow administrators to restore communication without a service call. In more mundane network applications, the obvious choices for out-of-band management would be a secondary network or a dial-up connection, but given the extremely remote nature of most cell towers, cellular broadband via 3G/4G modem is often the only viable option for out-of-band communication with a cell tower.
The Cisco 2509 router/hub has long been a favorite solution for network engineers who need reliable access to console port functions on remote network equipment. In fact, the Cisco 2609 did such a great job of providing remote console access that many network administrators continued to rely on the 2509 even after the product was discontinued in 2004. But now, nine years after the venerable 2509 was discontinued, network managers are faced with a new problem; Cisco 2509 units are getting increasingly difficult to find and in order to support the expanding access needs of a constantly growing network infrastructure, the time has come to find an appropriate replacement for the Cisco 2509 that’s both fully supported and readily available in large quantities.
Although the Cisco 2509 router/hub does a great job of providing remote access to console port command functions, it’s becoming increasingly difficult to find Cisco 2509 units since they were discontinued in 2004. As Cisco 2509 units become more and more rare, network engineers have recognized the need for a replacement for the Cisco 2409, that not only provides an access server solution, but is also readily available in the large quantities needed for network expansion, includes full technical support and also features updated security and authentication capabilities beyond those found on used Cisco 2509 units that date back to 2004 or earlier.
If you’re a network engineer, faced with the challenge of replacing Cisco 2509 routers, you should definitely consider the WTI TSM-DPE series access server as a drop-in replacement for the Cisco 2509. Although Cisco 2509 units continue to provide an efficient console access solution, it has become increasingly difficult to find Cisco 2509 units since their discontinuation in 2004. This means that in order to expand remote network management capabilities and provide remote console port access for more and more network devices, a suitable replacement for the 2509 is needed.
When an important network element located at an off-site data center or remote equipment rack suddenly locks up and refuses to communicate, the last thing you want to do is send a tech team off on a service call, merely to reboot the uncooperative network device or change a few communication parameters. A service call might seem like the obvious solution, but service calls are expensive, and the entire time that you’re waiting for the service team to reach the remote network equipment site, that important network device still refuses to communicate.
Most network administrators are fairly familiar with the concept of using a console terminal server to provide secure, reliable out of band management capabilities for offsite data centers and remote network equipment racks. It’s widely accepted that the out of band communication capabilities provided by a console terminal server can help to maximize uptime and cut maintenance costs for remote network equipment, but in addition to providing an avenue for out of band management, a full featured console terminal server product that includes monitoring and alarm capabilities can also help administrators to be kept better informed regarding conditions at distant network equipment installation sites.
Network administrators who are responsible for managing offsite data centers and remote equipment racks are often faced with two common challenges: a lack of information regarding conditions and events at the remote equipment site, and the inability to deal with problems at the remote site without traveling there in person or sending a service team. When vital network elements such as servers and routers are located at an offsite facility, often the only way to really get one’s hands on a problem at the remote site is to travel there in person; an effective solution, but often also an expensive, time-consuming solution.
In remote network equipment management applications, a network power switch can quickly prove itself to be an extremely valuable tool. In addition to providing network administrators with a simple, secure means to reboot malfunctioning network devices at remote equipment racks and off-site data centers, a network power switch also enables network administrators to cut power costs by switching off nonessential network devices during periods of the day/week when those devices are less likely to be needed.
