DGS-6600 Layer 3 Chassis Ethernet Managed Switch Hardware Installation Guide8DGS-6608 Hardware CompositionThe DGS-6608 hardware consists of a chassis, management card, line cards, power system and a fan system.ChassisThe DGS-6608 uses a standard 19-inch chassis. The chassis consists of the system module layer, fan layer, andpower layer.The layer that handles system modules consists of a module plug-in frame, which is used for connecting thevarious DGS-6608 modules.The built-in power shelf is located at the top of the chassis.The fan tray is located on the right-hand side of the chassis. The fan tray consists of Sixteen fans. The dimensionof each fan is 80x80x20mm.Module Plug-in FrameThe module plug-in frame of the DGS-6608 consists of the module slots and the backplane.The DGS-6608 supports eight module slots. The slots 4 and 5 of the Switch can only be used for the controlmanagement module. The other six slots can be used to connect to various line cards. All the modules supportedby the DGS-6608 are of the same height, width and depth. The dimensions of each module are a height of42mm, a width of 388mm, and a depth of 422mm. The modules of the DGS-6608 are inserted into the Switchhorizontally. The backplane of the DGS-6608 is used to interconnect the control management card and the linecards that have been installed in the Switch.The main functions of the DGS-6608 backplane are listed below:• Providing a mechanism for transmitting various signals between the modules and providing channelsfor high-speed communication.• Acting as a passive backplane.• Automatically identifying the type of line card that has been installed in each slot.• Managing the load distribution among the installed power supplies.When the slots of the DGS-6608 are fully populated, the modules of the DGS-6608 will have the following layout:• Two control management module.• Six line card modules to meet the network requirements.The slot number used for the Control Management module is 4 and 5. Slots 1-3 to 6-8 are used for line cardmodules.
