DGS-6604 Ventilation/Heat Dissipation System

The DGS-6604 operates at a temperature of 0-50ºC. The hardware of the DGS-6604 has been thermally

designed so the surface temperature of the components does not exceed the allowed ambient temperature of

50ºC without affecting the reliability, security, and repairability of the Switch. The thermal design of the DGS-6604

hardware uses fans to induct air in a forced convection so that the equipment operates normally in the specified

environment. The diagram below shows the ventilation/heat dissipation system that has been implemented on

the DGS-6604.

DGS-6608 Product Specifications

Product Features

• Powerful Expansion Capabilities

The DGS-6608 is capable of supporting strategic routing and IPv6. With support for multiple types of

line cards, the DGS-6608 allows users to customize their Switch configuration to meet their network

requirements.

• Hot-Swappable Line Cards, Fan Tray, and Power Supplies

The DGS-6608 supports the hot-swapping of line cards, the fan tray, and power supplies to

minimize disruption to the network when a fault occurs.

• Power Supply Redundancy

The DGS-6608 has two built-in power shelves that can host up to eight power modules. If the DGS-

6608 is running in a non-PoE environment, the Switch can operate using only two power supply. in a

worst case scenario with six 48-port PoE line cards installed, all 8 x PSUs inserting can meet the

power request. In this case, the system does not support RPS.

NOTE: The air flow direction for the DGS-6604 is from the left to the right.
