Module Plug-In Frame - D-Link DES-7200 Hardware Installation Manual

The system module layer is a module plug-in frame, which mechanically supports various
modules of the DES-7210 system.
At the bottom of the chassis are two power frames, above which are the air inlet layer. The
air filter is located between the air inlet layer and the cabling rack, which is located below the
system module l ayer. A bove t he s ystem module l ayer i s t he f an layer, which houses s ix
layers. At the top of the chassis is the air outlet layer, which works by the induced draught.

DES-7206 chassis
The DES-7206 uses a standard 19-inch chassis, whose standard height is 736.4mm, width
is 436. 8mm, and dept h is 508 m m. I t c onsists o f t he s ystem module layer, f an layer an d
power layer.
The functional module layer is a module plug-in frame, which mechanically supports various
modules of the DES-7206 system.
At the top of the chassis are two power frames. Located at the back of the chassis module
plug-in box, the fan layer is the house of six fans, which induct air.

Module Plug-in Frame

The DES-7210/7206 module frame consists of the module slots and backplane.
The DES-7210 offers 10 m odule slots, of which the two in the m iddle ar e for the
management modules only. The eight slots on both sides can accommodate a mix of various
user m odules. F or t he DES-7210, t he m odules ar e inserted vertically, a nd t hey hav e t he
same hei ght of 412 m m, depth of 350 m m, and t hickness of 2. 0 mm. The DES-7210
backplane i mplements t he interconnection of high-speed data links bet ween the switching
management c ards and m odule line c ards a nd t hat of v arious m anagement and c ontrol
signals.
The DES-7206 offers s ix module s lots, of w hich the t wo i n the middle are f or the
management modules only. The four slots on the upper and lower sides can accommodate a
mix of various user modules. For the DES-7206, the modules are inserted horizontally, and
they have t he s ame w idth of 412 mm, dept h of 350 mm, and t hickness of 2. 0 mm. The
DES-7200 backplane implements the interconnection of high-speed data links between the
switching management cards and module line cards and that of various management and
control signals.
