S12712

S12712 overview

Huawei S12712 series switch S12712 includes 2 MPU slots, 2 CMU slots, 12 LPU slots, 4 SFU slots, 6 Power Module slots, 5 Fan Module slots with 9120Mpps Forwarding performance, 17.44Tbps Switching capacity. This switch is one of the Huawei S12700 series switches.

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).

S12712 appearance and structure

The S12712 chassis is 19 U high (1 U = 44.45 mm). When the chassis has no cable management frames installed, the dimensions (H x W x D) are 841.75 mm x 442 mm x 517.4 mm. When the chassis has cable management frames installed, the dimensions (H x W x D) are 841.75 mm x 442 mm x 585 mm. Figure 1 and Figure 2 show the appearance of the S12712 chassis.

1. Two MPUs	2. Twelve 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 are supported by a switch depending on the software version. For details, see Hardware Query Tool.	3. Four SFUs	4. A pair of mounting brackets NOTE: The mounting brackets are used to secure the chassis in a cabinet.
5. Six 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 help route cables orderly.

1. Five 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. A pair of handles NOTE: The handles are only used for this purpose: After you lift the chassis onto the guide rails or tray, grasp the handles to drag the chassis in to the cabinet.
5. Air filter NOTE: The air filter prevents dust from entering the chassis.
