The High-Density Media Converter System II Chassis belong to a large family of modular media converter and communications options that provide an exceptional range of choices for your managed enterprise network. Extend your network over fiber optic cable, over ordinary phone wire via VDSL, even over T1. The High-Density Media Converter System II is particularly well suited for network-extension applications, offering a wide range of hot-swappable media converter modules for network extension over fiber.
Additionally, the system offers a range of modules such as T1/E1, VDSL, and ATM that are not usually available with chassis-based media converter systems. With more than 100 modules to choose from, this system can adapt to even the most demanding network configurations.
Many media converter modules perform Layer 2 media conversion, which increases the efficiency of your network compared with using a traditional Layer 1 media converter. All media converter modules are hot-swappable—you never need to power down a chassis to change a module. Choose from a wide range of chassis options ranging from tiny unmanaged desktop chassis for remote desktop locations to large rack mount chassis with embedded management for your IT center.
The High-Density Media Converter System II is easy to integrate into any managed network. Not only does the system support industry-standard SNMP, but fiber modules include LinkLoss™ and/or FiberAlert™ to alert you if a fiber link is interrupted. LEDs on each module show link status at a glance.
SNMP helps you diagnose network problems by monitoring both copper and fiber link status as well as the chassis’ temperature and voltage levels. SNMP traps can alert you to potential network failures so you incur less downtime and spend less time troubleshooting. You can assign a name to each of the various ports and if a link failure occurs, you’ll be notified with the port’s name. Each manageable chassis includes a CD-ROM that contains management software. This software enables you to configure the chassis and its modules in minutes and provides you with a cross-platform application for managing intelligent networking devices from virtually any 32-bit Windows® system.
It also includes MIBs for SNMP. Compatible with Windows 95/98, Windows 2000, Windows NT® 4, and HTML, the user-friendly, comprehensive program uses a clear graphical user interface (GUI). It even shows an on-screen representation of the actual device control panels and gives you detailed information about the conversion ports. You can also use the included MIBs with any standard SNMP program, such as HP® OpenView®. This enables you to view SNMP’s in-depth technical data in the software’s easy-to-use interface. You can even display statistics as charts.
Modules in unmanaged chassis can also be managed, although the chassis themselves cannot. Chassis with Modular SNMP Management. These heavy-duty chassis are manageable through a separate SNMP Management Module. Choose from a 1U, 6-slot chassis or a 3U, 20-slot chassis. Each chassis has one additional slot for the SNMP module. You can install chassis with modular SNMP Management as unmanaged chassis and then add SNMP later—a perfect solution for an unmanaged network that might migrate to a managed network at a later date.
In situations where you need to disable chassis management, simply move the built-in SNMP switch to the off position. Even though this makes the modules unmanageable, the SNMP agent continues to communicate with installed modules. Turning management back on returns the modules to management control and any settings you’ve set in software.
A chassis that has its management enabled can be connected to a switch or other network device via a CAT5 straight-through twisted-pair cable that you plug into the unit’s external 10BASE-T (RJ-45) connection. An SNMP write-lock switch protects the configurations of your installed modules from being accidentally overwritten. Because the chassis have an embedded DHCP agent, their IP addresses are dynamically assigned when connected to a LAN with a DHCP server.
Models with dual power supplies eliminate a point of failure. Plus, a “last gasp” feature alerts you when one of the power supplies or AC power fails. And there are even more features to ensure reliability: The dual fans are easily field replaceable in the 20-slot chassis. In the 6-slot chassis, fans activate only when the chassis reaches a preset temperature. Fan speed and chassis temperature can be monitored remotely via SNMP.
The chassis come with blank plates installed and include rack mounting hardware. Chassis with Embedded SNMP Management Chassis with Embedded Management have SNMP already built in. The SNMP agent is embedded in the chassis backplane, eliminating the need to install a separate management module or software in your system. Just add media converter modules and you’re ready to go.
The 2-port models feature a small footprint, house two media converter modules, and come with an AC or a DC power supply. They’re perfect for desktop use.
For medium-size applications, order the 8-port model, also available with an AC or a DC power supply.
For central office (CO) use, order the 18-port chassis, which we offer with either an AC or a DC power supply. Although the 18-slot chassis comes with its AC or DC power supply already installed, you can order a second power supply in the form of a module that slides into the chassis.
The 18-slot chassis comes with blank plates installed and includes rack mount hardware.
You can also choose from a 1- or 2-slot Unmanaged Chassis for desktop use. Although these chassis are unmanaged, modules within them can be accessed through a managed chassis in the same system.
Tiny 1-Slot Chassis are perfect for when you only need to add one fiber link to bring fiber to the desktop. They hold one media converter module and are powered by either an autosensing 115-/240-VAC power supply or a dual AC/DC power supply.
The model with the dual AC/DC power supply is ideal for industrial environments. It features AC power supplies and DC 4-screw terminals, and it operates in -40 to +70° C environments. A mounting clip enables you to mount it on a DIN-35 rail.
The 2-Slot Desktop Chassis features a small footprint, house two media converter modules, and come with an AC or a DC power supply.
In addition to internal power supplies, all chassis feature redundant, 6.8-cfm-rated cooling fans to keep them from becoming overheated, causing downtime. Making the most of available bandwidth becomes more important as Internet use increases. To allocate bandwidth in the most cost-effective way within a network LAN/WAN environment, add a Bandwidth Manager to any of the chassis. Ideal for Web hosting, server co-location, and service provider applications, this 2-port networking device enables you to easily and inexpensively control bidirectional bandwidth in 1-kbps increments up to 10 Mbps.
