Why Does a Console Server Need SSHV2 Encryption Capability?

Tuesday, September 7th, 2010

Most network administrators know that the main reason for adding a console server to your network equipment rack, is to provide remote access to command functions on servers, routers, switches and other network devices. Remote access capabilities provide administrators with the ability to manage and maintain network equipment without the requirement to travel to the installation site in order to access these functions directly. But as handy as remote access is, it also presents a bit of a conundrum: a console server needs to allow authorized personnel to access command functions, while also ensuring that unauthorized personnel are kept out.


Can Your Console Switch Tell You When Equipment is Misbehaving?

Saturday, August 28th, 2010

Most console switch products can provide network administrators with vital tools to allow management and troubleshooting capabilities for network devices at remote installation sites, but wouldn’t it be handy if your console switch could also automatically notify you when a network device ceases to function? WTI console switch products include a heartbeat feature, which when used in conjunction with our “Lost Communication” alarm, can immediately notify you when compatible devices, hang, fail, crash, or just stop working.


What Can SNMP MIB Support Do for Your Data Center?

Thursday, August 26th, 2010

SNMP MIB support provides a crucial element for console switch applications. MIB support enables the console switch to address and interpret commands issued by 3rd party software such as OpenView or Solaris, essentially allowing the console switch to accept commands and poll information via the 3rd party software.


Remote Console and Power Management for Cisco Routers

Tuesday, August 17th, 2010

All servers and routers will lock up and cease to function sometimes; even top quality equipment like Cisco routers and switches.

Have you ever been woken up in the middle of night by a call from work, and then had to drive all the way to your office just to unlock or reboot an uncooperative router? Does all work at your office regularly grind to a halt every time a piece of network equipment gets a case of the hiccups? Have you ever watched helplessly as constant “truck rolls” to remote equipment sites gradually eat up your yearly budget and tie up your most valuable employees?


SNMP Network Control …

Thursday, August 12th, 2010

SNMP based control and monitoring of remote network devices is a valuable tool for almost any network administrator. WTI’s Serial Console Servers and Switched PDUs provide full MIB support, allowing you to review status, change configuration parameters, edit user privileges and control operating functions at remote units via SNMP commands.


DC Powered Console Server Applications in the Central Office …

Wednesday, August 11th, 2010

WTI’s console server products are often used in -48VDC powered central office applications. Historically, these products have often been used by the Telco industry for communication with network elements via console or craft ports. In addition to our console server products, WTI also manufactures a line of dial-up, rack mount, -48VDC powered modems which are also ideal for central office applications.


Why Do Console Switches Offer Multiple Different Types of Security and Authentication?

Monday, August 9th, 2010

When one looks at the incredible variety of different applications for network based technology, it’s not surprising that there are also an incredible variety of differing security needs for network equipment. And since a console switch is designed to provide secure, remote access to a variety of different types of network equipment, it follows that a console server should also be compatible with a variety of different types of security measures.


Different Access Rights for Different Types of Console Server Users …

Friday, August 6th, 2010

In most network management applications, a console server may have many different users. In addition to allowing access by IT Administrators, it’s not uncommon for console servers to provide access to other users who may be responsible for a specific network device or collection of devices; in some cases, an individual department might have its own, lower-level IT techs, who also need access to console server functions too. This multiplicity of users presents an interesting challenge for the IT Administrator: how do you provide different levels of access for different level users, while still assuring that critical configuration functions remain secure?


Need a Serial Switch with IP Address Filtering?

Thursday, August 5th, 2010

Typically, a serial switch is used to provide remote access to command functions on network equipment such as servers, routers and firewalls. Remote access is an important capability for any network administrator, in that it allows problems at far-away installation sites to be addressed and solved without physically traveling to the site. Many modern network applications would be economically unfeasible without a serial switch and the ability to access command functions on remote devices that a serial switch provides.

Yet even so, as important as a serial switch is, it would be practically useless without proper security measures in place to protect sensitive command functions from unauthorized users.


Why Does a Console Switch Need a Real-Time Clock?

Tuesday, August 3rd, 2010

The ability to accurately record the time and date is a vital feature for console switch products. When reviewing alarm records or scheduling actions, it’s extremely important to know that the console switch has accurately and reliably recorded the correct time and date. Without the correct date and time, much of the data that is recorded by a console switch can often be rendered more or less useless; if you don’t know exactly when a recorded event took place, it’s difficult to use that data for troubleshooting or scheduling purposes.
