With Black Box® Value Line Console Servers, there’s no need to spend a lot for efficient, remote console server management.

Available in 8-,16-,and48-portversions, these versatile devices give youout-of-bandserial console port control in a secure platform that fits the budget of small tomedium-sizebusinesses as well ascash-strappededucational, healthcare, and government institutions.

With Value Line Console Servers, you can get access to data center systems for reliable 24/7 uptime without sacrificing security, flexibility, and interoperability with your current server environment.

Use a Value Line Console Server as a gateway to remotely access servers, virtual servers, and similar network IT equipment. You can also reach routers, switches, firewalls, PBX systems, and many other network infrastructure devices—aswell as UPS and RPS power systems!

Another benefit: The Value Line Console Servers provide easy access to service processors. Many pricier console servers don’t, which can be a real shortcoming if you want to connect to today’s newer servers that include service processor cards or sideband interfaces by default.

Even better, the Value Line Console Servers use the Linux® OS platform, so there’s no dealing with proprietary protocol issues when you want to customize it to your specific requirements (a developer kit is included to help you get started). Use thisopen-sourceplatform to reach ports on Linux, Windows, Sun®, HP®, and IBM® servers. In addition, the console servers come with Nagios network monitoringplug-insto centrally manage servers and other resources distributed across an application.

IN Depth

Reach equipment out of band securely.

In addition to remote in-bandaccess through its10BASE-T/100BASE-TXTCP/IP port, Value Line Console Servers supportout-of-bandaccess to your critical equipment and vital assets.

Just attach an external dialup modem to control and manage your distributed network of servers and other devices with the latest in console access. Typically, you do this via Telnet software, using an SSH tunnel through the console server to communicate securely with serial port-connecteddevices over the Internet or any other public network. But you can Telnet through the console server to the serial device several other ways, too. (See “LAN Console Port Management” and “Serial Console Port Management” in the Tech Specs on page 4.)

Value Line Console Servers come with an SDT Connector application. Through this open-sourceSSH Java client, youauto-loadyour console server’s configurations and, to ensure secure connectivity with attached network and serial devices, set up SSH tunnels forport-forwardingcommunications through the console server. The same SDT Connector tool is also used for setting up a10-/100-Mbpsauto failover route to

a remote, out-of-bandgateway. This can be through an alternatedial-inpath orout-of-bandbroadband path.

Robust advanced encryption keeps all connection communications secure. In addition, the console servers give you a choice of filtering and access logging facilities, which you can archive off-line.Store offline logs for serial ports, available networks, and more. And to protect against unauthorized access, the system enables you to restrict access by IP address, password, or account.

Set up to scan the serial stream and send alerts.

To help ensure maximum uptime, Value Line Console Servers proactively scan the serial stream on console ports, searching for specific errors and phrases.

The console servers support SNMP and SMTP alerts/traps for serial ports and hosts. Simply set the trigger condition for each port, and the console server monitors port traffic for your defined character stream pattern or phrases. If they’re detected, the console server sends SMS text or an e-mailto you or an SNMP server (or to a central Nagios server, if it’s used). This alerts feature can be enabled on any and all serial ports or connected hosts.

Also, the console server informs you of its operating status. An LED on the back of the unit flashes a “heartbeat” periodically, and its “heartbeat monitor” agent can trigger dial-backor a redundant path

during network outages. The heartbeat monitor checks that the console server is indeed on-lineand operating as it should, that it’s clear to send alerts and alarms, and is accessible by remote users. In addition, you can set it up so if the heartbeat falters, it can automatically dial up a remote site to raise an alarm, or switch to and activate a failover link.

Through a serial connection, you can access the Value Line Console Server’s RPC menu to select your type of serial RPC device. The console servers support most popular network and serial PDUs. And if your PDU isn’t on the default list, then you can add support directly.

Both administrators and users can access and control serialand networkattached PDU power strips. You can initiate the action you want to take by outlet, whether it’s turning it on or off, cycling, or checking its status.

Hotkey power on a PDU or an RPS.

A Value Line Console Server is also the ideal solution for situations where you need out-of-bandaccess to a “dead” communicationsdevice—onethat’s entirely locked up in a frozen condition.

Using a hotkey from the command line interface via SSH or Telnet, you simply launch the console server’s remote power control (RPC) menu, through which you can turn power on (or off), power cycle, or just check the power status of a particular device. Or you activate

power status control and monitoring through SNMP. Value Line Console Servers support thousands of PDU or RPS units, for both serialand SNMP-connectedcontrol.

MORE Applications

In branch offices, use Value Line Console Servers to:

»Simplify the control of distributed office server rooms or wiring closets containing servers, UPSs, PDUs, and network devices.

»Set up a centralized in-bandandout-of-bandmanagement gateway for local and remote serial portmanagement—especiallyfor satellite offices with little or no IT staffon-site.

»Ensure maximum system uptime for sales offices, the customer-facingpoints crucial to the bottom line of many business enterprises.

»Give off-sitetechs 24/7 access to integrated small business server applications, those that branch offices often depend on fore-mail,printing, file storage, Web access, and more.

In smaller service provider applications, use them to:

»Better serve the IT needs of clients in different offices by keeping servers and equipment up and running on a continuous basis.

»Support new services while at the same time reducing the need for on-siteservice calls and increasing profitability.

»Avoid the need for numerous high-pricedmanagement devices (dedicated power switch controllers, service processor management units, KVMoIP switches, etc.) at the client site.

»Proactively diagnose client-sideequipment problems, setting up notification alarms and alerts to notify you of pending IT disasters.





Supports GNU bash shell script.

Some products in today’s market use proprietary protocols for communications. In contrast, Value Line Console Servers give you access to the Linux core, including bash. This makes them ideal for industrial control applications where you need to remotely manage proprietary equipment with custom protocols.

Through the Linux kernel, you can write custom scripts that can run manually or automatically. This way, you proactively create self-healingsolutions for cycling power on a router or switch on PING failure.

You can write custom scripts so they run each time a particular alert triggers. For example, you can set it up to power cycle on a managed device when a specific alert event occurs or to send multiple notification e-mailswhen an alert triggers.
