TYPE:AP Controller

Introduction:DCWS-8504is a high-performance smart Chassis type access controller (AC) independently developed by Digital China Networks Co. Ltd.this product is based on DCNOS

DCWS-8504is a high-performance smart Chassis type access controller (AC) independently developed by Digital China Networks Co., Ltd.,this product is based on DCNOS operating system which has DCN independent intellectual property rights. The product has high performance of Ethernet characteristics, characteristics of mature IPv6, multi plane separation design with high reliability, high performance of L2/L3 exchange, rich fine QoS strategy, powerful radio service support and integrated security features.


DCN provides network services based on authentication, this method is based on the identity of the user rather than the port or device, it realizes the mobility and security across the network. When users roam in the network, it can use WLAN to complete information interaction, and perform access and consistent security policy within the scope of the entire network, it supports safety standards of WAPI and 802.11i , effectively guarantee the safety of all kinds of information and data.

DCWS-8504 high-end wired and wireless integrated intelligent controller supports redundancy control, can support the two main control board and two interface board block, supports up to 4096 AP management, can meet the deploy demand of large campus wireless network and wireless network operators. The board, power supply, fan support hot swappable, provides the reliability for DCWS-8504.


DCWS-8504 wireless access controller can be deployed in any of the existing Layer 2 or 3 combined with DCN intelligent AP; there is no need to have the network reconfiguration.
