DGS-6604 Hardware Composition

The DGS-6604 hardware consists of a chassis, management card, line cards, power system and a fan system.

Chassis

The DGS-6604 uses a standard 19-inch chassis, which has a height of 280mm, a width of 484mm, and a depth
of 470mm. The chassis consists of the system module layer, fan layer, and power layer.
The layer that handles system modules consists of a module plug-in frame, which is used for connecting the
various DGS-6604 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 eight fans. The dimension of
each fan is 80x80x20mm.

Module Plug-in Frame

The module plug-in frame of the DGS-6604 consists of the module slots and the backplane.
The DGS-6604 supports four module slots. The slot at the top of the Switch can only be used for the control
management module. The other three slots can be used to connect to various line cards. All the modules
supported by the DGS-6604 are of the same height, width and depth. The dimensions of each module are a
height of 42mm, a width of 388mm, and a depth of 422mm. The modules of the DGS-6604 are inserted into the
Switch horizontally. The backplane of the DGS-6604 is used to interconnect the control management card and
the line cards that have been installed in the Switch.
The main functions of the DGS-6604 backplane are listed below:
• Providing a mechanism for transmitting various signals between the modules and providing channels
for 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-6604 are fully populated, the modules of the DGS-6604 will have the following layout:
• One control management module.
• Three line card modules to meet the network requirements.
The slot number used for the Control Management module is 1. Slots 2, 3, and 4 are used for line card modules.
