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.

 

Table 1 Types of copper cables
Model	Length	Electrical attribute	Bend Radius	Connector Type	Part Number
LS2MCABLE000	1.5 m	Passive	25 mm	SFPto SFP	02316279
SFP-10G-CU1M	1 m	Passive	25 mm	SFP+ to SFP+	02310MUN
SFP-10G-CU3M	3 m	Passive	25 mm	SFP+ to SFP+	02310MUP
SFP-10G-CU5M	5 m	Passive	30 mm	SFP+ to SFP+	02310QPR
SFP-10G-AC10M	10 m	Active	25 mm	SFP+ to SFP+	02310MUQ
QSFP-40G-CU1M	1 m	Passive	35 mm	QSFP+ to QSFP+	02310MUG
QSFP-40G-CU3M	3 m	Passive	40 mm	QSFP+ to QSFP+	02310MUH
QSFP-40G-CU5M	5 m	Passive	45 mm	QSFP+ to QSFP+	02310MUJ
QSFP-4SFP10G-CU1M	1 m	Passive	25 mm	QSFP+ to 4*SFP+	02310MUK
QSFP-4SFP10G-CU3M	3 m	Passive	25 mm	QSFP+ to 4*SFP+	02310MUL
QSFP-4SFP10G-CU5M	5 m	Passive	30 mm	QSFP+ to 4*SFP+	02310MUM
QSFP28-100G-CU1M	1 m	Passive	70 mm	QSFP28 to QSFP28	02311KNW
QSFP28-100G-CU3M	3 m	Passive	70 mm	QSFP28 to QSFP28	02311KNX
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.
