The CCN-2000 chassis sets a high standard for enclosure fit and

finish.  The 19-inch wide, 2U high, black chassis contrasts with the

gold anodized faceplates of its twenty media conversion card

modules. Unique features include: a full width (across the front) air

inlet chamber to ensure superior cooling across all cards; rack

mounting brackets with two sets of screw hole patterns (one set

allows for a more recessed position in the rack, the other positions

the CCN-2000 chassis to maximize cooling air in-flow); and a single

chassis-wide cross bar, using two thumb screws, locks in-place all

modules (releasing the thumb screws allows the bar to drop down,

clearing the way for easy card insertion).  Each chassis comes standard

with one auto-sensing AC Power Supply and integrated Fan

assembly.  The CCN-2000 can be ordered with an optional

Redundant Power Supply and integrated Fan, or a negative 48

VDC Power supply with integrated Fan assembly.

Alternatively, a separate intelligent FAN module, [CN-20RFAN] may

be installed for additional cooling capacity.  Each Power Supply and

FAN module has on-board (1) an environmental air temperature

sensor, (2) analog-to-digital converters to measure power voltages,

and (3) a Hall-effect sensor for measuring fan rotation – an innovation

used for early fault detection.  Each Power Supply or FAN module

has an externally visible bi-color status LED that displays green

when all measured performance variables are within range and

red when otherwise.

The compact, Manageable four-slot CCN-0400 uses the same CCN-

2000 card modules and has similar features.  The CCN-0400 has

several built-in system sensors to monitor chassis function.  As in

the CCN-2000, there is (1) an internal environmental air temperature

sensor, (2) analog-to-digital converters to measure power voltages,

and (3) a Hall-effect sensor for measuring fan rotation and reporting

non-normal operation.

The CCN-2000/CCN-0400 product group has continued to expand

its capabilities with the addition of Single-Fiber, Bi-Directional

converters, converters with active CWDM (Coarse Wavelength

Division Multiplexing) transceivers, and passive four and eight-

channel CWDM Multiplexer / De-multiplexer modules.  Expected

soon are the additions of High speed 1.062 Giga-Baud Fibre Channel

Fiber-to-Fiber cards, six-port Switch modules with a Gigabit uplink

port, a Multi-Rate media card supporting data rates spanning 10

Mbs through 2.7 Gigabits per second and a 10 Gigabit Fiber-to-

Fiber card.  These product additions will enable users of the large

installed base of CCN-2000s to upgrade and keep their units current

as network bandwidth and protocol needs continue to evolve.  In

the future, the CCN-2000 and CCN-0400 Chassis group will

continue to serve as the platform for a wide range of innovative

connectivity products. The CCN-400 has no provision for a

redundant Power Supply or Fans, and is not loadable with  (4 & 8

channel) Coarse Wavelength Division Multiplexer modules.
