Brief Introduction of Cables in the Switches

Various cables play an important role in the healthy operation of Huawei Switches, today we are about to introduce the dedicated stack cables and copper cables.

Types of Dedicated Stack Cables

We list the applicable dedicated stack cables.

Table 1 Dedicated stack cables
Model Length Electrical Attribute Bend Radius Connector Type Part Number
SFP-10G-CU0M5 0.5 m Passive 25 mm SFP+ to SFP+ 02311VGK
SFP-10G-CU1M5 1.5 m Passive 25 mm SFP+ to SFP+ 02311VGN

Each dedicated stack cable has a Master tag on one end, and the untagged end is the slave end.

Stack Setup

Dedicated stack cables can only be used to connect certain switch models, enabling them to set up a stack without manual configuration. For details on how to connect the stack cables, see the printed Dedicated Stack Cable Connection Guide delivered with the cables.

Before setting up a stack, confirm the stack connection mode supported by the member switches, as well as the hardware and software requirements. For details, see “Determining the Stack Connection Support and Mode” under “Typical Stack Configuration of Fixed Switches” in the Typical Configuration Examples.

Types of Copper Cables

We list the types of copper cables.

QSFP28-100G-CU5M 5 m Passive 70 mm QSFP28 to QSFP28 02311KNY

The two ends of a copper cable must be covered by electrostatic discharge (ESD) caps.

When used for data transmission between service ports, copper cables can only connect Huawei switches of the same subseries. These copper cables cannot be used between Huawei switches of different subseries or between Huawei switches and other devices such as PCs, hosts, servers, or routers.

Stack Description

In addition to data transmission, copper cables can be used for stack connection.

Before setting up a stack, familiarize yourself with the device-supported stack connection modes and software and hardware requirements. For details, see “Determining the Stack Connection Support and Mode” under “Typical Stack Configuration of Fixed Switches” in the Typical Configuration Examples.
