Notice The purchased products, services and features are stipulated by the contract made between Huawei and the customer. All or part of the products, services and features described in this document may not be within the purchase scope or the usage scope. Unless otherwise specified in the contract, all statements, information, and recommendations in this document are provided "AS IS"...
Intended Audience This document describes installation procedures, troubleshooting methods, and maintenance instructions for the S2700, S3700, S5700, and S6700 series switches. This document is intended for network engineers responsible for switch installation and maintenance. You should have experience in network device installation and maintenance.
Battery LAN switches S5700-28P-LI-BAT and S5700-28P-LI-24S-BAT are not described in this document. For details about the installation and maintenance of these switches, see the S5700-LI-BAT Installation and Maintenance Guide. The S2700, S3700, S5700, and S6700 switch models differ in appearance and dimensions, as shown in Figure 1-1.
In addition, drilling holes produces metal shavings that may enter the cabinet and cause short circuits on printed circuit boards (PCBs). 3.2 Checking the Installation Site The S2700, S3700, S5700, and S6700 series switches are used only in indoor equipment rooms. Table 3-1 describes the requirements for the installation site.
3.3 Checking the Cabinet or Rack Table 3-2 describes the requirements for the cabinet or rack where an S2700, S3700, S5700, or S6700 series switch will be installed. Table 3-2 Requirements for the cabinet or rack...
3.4 Checking the Power Supply System The power supply system must be ready before the installation. Table 3-3 describes the requirements for the power supply system of the S2700, S3700, S5700, and S6700 series switches. Table 3-3 Power supply requirements Item...

Warranty seal NOTE Huawei is unable to provide warranty services if the warranty seal is damaged or removed. Step 7 Check whether the nameplate on the chassis is consistent with the label on the carton. The nameplate is attached to either the top or bottom of the chassis.
5.3 Scenario 2: Desk Mounting 5.4 Scenario 3: Wall Mounting 5.5 Scenario 4: Top Wall Mounting 5.6 Connecting the Ground Cable 5.1 Installation Scenario Overview The S2700&S3700&S5700&S6700 switches of different sizes support different installation scenarios, as described in Table 5-1, Table...
5.2 Scenario 1: Cabinet/Rack Mounting 5.2.1 Using Front Mounting Brackets Context This installation method applies to S2700, S3700, S5700 (except S5710-EI, S5710-HI, S5720-SI (420 mm depth), S5730-SI, S5730S-EI, S5720-C-EI, S5720-PC-EI, and S5720-HI), S6700-EI, S6720S-EI, S6720-LI, and S6720S-LI switches. Follow these precautions before or during the installation: Ensure that the cabinet is stable and meets the requirements specified in 3.3 Checking...
The methods for installing different types of power modules in a switch are the same. All the power modules are hot swappable (except the 870 W PoE power module). For the S2700, S3700, S5700, and S6700 switch models that support pluggable power modules, see the Hardware Description.

Ensure the correct polarity of connected cables. If you use DC power cables delivered from Huawei, connect the -48 V return ground cable (black) to the RTN(+) terminal, and connect -48 V power cable (blue) to the NEG(-) terminal.

Hardware Installation and Maintenance Guide 7 Connecting a Switch Some models of the S2700, S3700, S5700, and S6700 series switches can set up a stack using service ports or stack cards. Stack card connection: Member switches are connected using dedicated stack cards and stack cables.
Never look directly into an optical module or the ends of optical fibers. Optical modules and connected fibers emit laser radiation that will cause eye damage. NOTICE Use optical modules certified for Huawei switches. Using other optical modules may affect service stability and Huawei can accept no liability for the outcome. NOTICE Ensure that the new optical module has the same center wavelength and complies with the same standards as the old one.
Install the power module in another switch, or install another power module in this switch. – If the power module is faulty, send it to Huawei for repair. – If the device is faulty, contact technical support of Huawei or the equipment supplier. 12.1.2 A Switch Cannot Be Powered On...
If it is a pluggable power module, replace it with another one. If the switch powers on, the original power module is faulty. If it is a built-in power module, contact technical support of Huawei or the equipment supplier. If the switch still cannot power on, the switch is faulty. Contact technical support of Huawei or the equipment supplier.
If the transmit power remains low, replace the optical module or install it in another optical port to check whether it is faulty. If the optical module is faulty, send it to Huawei for repair or contact Huawei technical support.
Precautions for Assembly Use dedicated tools or tools delivered by Huawei and follow the methods given here during assembly. Hold terminals of cables instead of pulling the cables themselves when installing or removing cable components.

When you strip a power cable, do not damage the conductor of the cable. l If the bare crimping terminal is not provided by Huawei, the value of L1 is 1 mm (0.04 in.) to 2 mm (0.08 in.) greater than the value of L.

Testing the Connection of Assembled Cables Context Huawei provides two types of Ethernet cables: straight-through cables and crossover cables. Straight-through cables are connected in a one-to-one manner. They are used to connect terminals such as a computer or switch to network devices.
For example, in this document, the adapters of cable connectors have separate interfaces. In the actual situation, the adapters may have interfaces fixed on equipment. Use dedicated tools provided or specified by Huawei and follow the installation procedure described here.
