Slots on the S16700-4

Slot Type	Slot ID	Slot Direction	Remarks
LPU slot	Slots 1 to 4	The top of the board faces upwards	Different types of LPUs can be installed in the same chassis.
MPU slot	Slots 5 and 6	The top of the board faces upwards	Two MPUs work in active/standby mode for 1:1 hot standby. By default, the MPU with a smaller slot ID is the active MPU, and the MPU with a larger slot ID is the standby MPU.
SFU slot	Slots 1 to 9 Note: For the slots in which SFUs can be installed, see the "IDs of Available Slots" column in "Version Mapping" under "Cards > SFU".	The right side of the board faces upwards	SFUs work in load balancing and redundancy mode. SFUs in the same chassis must be the same model. That is, SFUs of different models cannot be installed in the same chassis.
PM slot	Slots 1 to 6	The indicator light end upwards	PMs are plug-and-play. PM4 to PM6 in the chassis with the part number 02355HUL-001 are reserved.
Fan module slot	Slots 1 to 3	The indicator light end upwards	At the normal temperature range, the system can operate properly for a short time after a single fan module fails. You are advised to replace the faulty fan module immediately.

S16700-4 FAQ

Q1: What is the maximum number of ports that can be expanded? Which line card models are supported?

A1: It supports a maximum of 32 10GE ports, 16 25GE/40GE ports, or 8 100GE ports; it is compatible with the entire series of Huawei line cards, including the LE0DX16XSA00 (16-port 10GE) and LE0DX8X25SA00 (8-port 25GE), offering flexible expansion.

Q2: What are the differences between it and the Huawei S16700-8? What scenarios is it suitable for?

A2: The core difference lies in the number of slots (4 slots vs. 8 slots). The S16700-4 has moderate expansion capabilities and a lower price, suitable for small to medium-sized cores/large aggregations; the S16700-8 is suitable for medium to large-sized cores, and both have the same performance.

Q3: Does it support stacked deployment? How does it improve network reliability? A3: Supports IRF2 stacking, allowing up to 4 devices to be stacked into 1 logical device, improving port scalability and redundancy; it can also achieve dual-core backup via VRRP, enabling seamless service switching in the event of a single device failure.
