Figure 1-4 Ventilation/Heat Dissipation Solution of the DES-7206

Note

This structure is designed with air inlet from the front panels of the

modules, and air outlet at the back. Six 120*120*38 fans are used to blow

the air to the outside for convection and ultimately heat dissipation.

Therefore, the chassis should be mounted at a place with adequate

spacing around for air circulation.

1.6 DES-7206/7210 Modules

DES-7210/7206 supports the modules described in Table 1-1.

7200-CM1~CM4: A s t he s witching a nd c entral c ontrol m odule of t he DES-7210/7206, th e

7200 Comtrol Modules implements the management of t he entire system, including L2/L3

processing, r oute m anagement, c ontrol an d m anagement us er ac cess, and ne twork and

operation maintenance.

7200-24G module: I t provides 12 10 00BASE-X SFP i nterfaces and 12 o ptical-electrical

multiplexing 1000M interfaces and supports up to 24 1000BASE-X SFP interfaces or

supports 12+M 1000BASE-X SFP interfaces and N 10/100/1000BASE-T interfaces, where

M plus N equals 12. It features the functions of layer-2/3 wire speed switching and routing,

and supports multi-mode SFP with the wavelength being 850nm, single-mode SFP module

with that being 1310nm, and long-distance SFP module and SFP copper interface with that

being 1550nm.

7200-24: It provides twelve 10/100/1000BASE-T electrical ports and twelve optical/electrical

combo 1000M interfaces, and supports up to twenty-four 10/100/1000BASE-T interfaces or

12+M 10/ 100/1000BASE-T i nterfaces and N 100 0BASE-X i nterfaces, w here M pl us N

equals 12. I t f eatures t he f unctions of l ayer-2/3 wire s peed s witching and r outing, an d

supports multi-mode SFP with the wavelength being 850nm, single-mode SFP module with

that being 1310nm, and long-distance SFP module and SFP copper interface with that being

1550nm.

7200-48: It pr ovides forty-four 10/100/1000BASE-T 1000M electrical p orts and f our

optical/electrical combo 1000M interfaces, and supports up to forty-eight

10/100/1000BASE-T interfaces, or 44+M 10/100/1000BASE-T interfaces and N

1000BASE-X interfaces where M plus N equals to 4. It features the f unctions of layer-2/3

wire s peed s witching an d r outing, an d 850nm s upports m ulti-mode SFP, 13 10nm

single-mode S FP m odule, and 1550nm l ong-distance S FP m odule an d S FP c opper

interface.
