S12704

S12704 overview

HUAWEI S12700 series agile switches (S12700 for short) are designed for next-generation campus networks. Using a fully programmable switching architecture, the S12700 allows fast, flexible function customization and supports smooth evolution to Software-Defined Networking (SDN). The S12700 uses a Huawei Ethernet Network Processor (ENP) and provides a native Wireless Access Controller (AC) to help build a wired and wireless converged network. Its Unified User Management capabilities deliver unified user and service management, and Huawei’s Packet Conservation Algorithm for the Internet (iPCA) supports hop-by-hop monitoring of any service flows, helping manage services in a more refined way.
The S12700 runs the Huawei Versatile Routing Platform (VRP), which provides high-performance L2/L3 switching services and rich network services, such as Multiprotocol Label Switching (MPLS) VPN, hardware IPv6, desktop cloud, video conferencing. In addition, the S12700 series uses a variety of reliability technologies, including non-stop forwarding, hardware Eth-OAM/BFD, ring network protection, and Cluster Switch System Generation2 (CSS2) — a switch fabric hardware clustering technology that allows 1+N backup of Main Processing Units (MPUs). These technologies help improve productivity and maximize network operation time, reducing the Total Cost of Ownership (TCO).

S12704 appearance and structure

The S12704 chassis is 10 U high (1 U = 44.45 mm). When the chassis has no cable management frames installed, the dimensions (H x W x D) are 441.7 mm x 442 mm x 517.4 mm. When the chassis has cable management frames installed, the dimensions (H x W x D) are 441.7 mm x 442 mm x 585 mm. Figure 1 and Figure 2 show the appearance of the S12704 chassis.

 

1. Two MPUs	2. Four of the following service cards can be installed: Open Service Platform Unit 1000M Interface Card GE/10GE Interface Card 10GE Interface Card 40GE Interface Card 40GE/100GE Interface Card 100GE Interface Card NOTE: The cards supported by a switch depending on the software version.	3. Two SFUs	4. A pair of mounting brackets NOTE: The mounting brackets are used to secure the chassis in a cabinet.
5. Four power modules	6. Two CMUs	7. Front ESD jack NOTE: The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded.	8. Cable management frames NOTE: The cable management frames separate cables on different cards and helps route cables orderly.

1. Two Fan Module	2. Rear ESD jack NOTE: The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded.	3. JG ground terminal NOTE: The two-hole OT terminal of a ground cable can be connected to the screws to ground the chassis.	4. Air filter NOTE: The air filter prevents dust from entering the chassis.
5. A pair of removable handles NOTE: You can install these handles on two sides of the chassis to lift the chassis.
