Installing a Power Module

• The installation methods for different power modules are the same.
• For information about the power module supported by your model, see Power Module in the
• HarHardwdwarare Descripte Descriptionion of your switch on the Huawei support website.
• All the power modules are hot swappable (except the 870 W PoE power module).
• When installing a power module, slowly push it into the slot. If you feel resistance or find the module inclined, pull the module out and push it into the slot again. Do not push the module with force; otherwise, the connectors on the module and backplane may be damaged.
• If only one power module is installed, install a power module filler panel in the empty power module slot. It is recommended that you install two power modules in a switch to enhance power reliability if the switch supports double power modules.

Installing Cards

Before You Start

• The installation methods for different pluggable cards are the same.
• For information about the cards supported by your model, see Cards in the of your switch on the Huawei support website.
• Only switch models S5700-SI, S5710-LI, and S5700-EI do not support hot-swappable cards. Cards that do not support hot-swappable cannot be installed when the switch is running. You must power off the switch, install the cards, and then power on the switch to activate the cards. To use a front 4xGE or 4x10GE optical interface card on the S5700-SI, S5710-LI and S5700-EI, you must also install an extended rear card ES5D00ETPB00. Otherwise, only two ports instead of four ports on this optical interface card are available.
• When installing a card, slowly push it into the slot. If you feel resistance or find the card inclined, pull the card out and push it into the slot again. Do not push the card with force; otherwise, the connectors on the card and backplane may be damaged.
• Install filler panels in vacant slots.

Installation Procedure

Step 1 Use a Phillips screwdriver to loosen the captive screw on the filler panel.
Step 2 Pull the filler panel out by the captive screw. Keep the filler panel for future use.
Step 3 Turn the ejector lever of the card 45 degrees outward. Push the card into the chassis with your thumbs (below the captive screws), until the screw on the front panel is completely in the chassis. Front cards for the S3700-HI, S5700-HI, and S5710-HI have no screws, but the installation method is the same.
Step 4 Rotate the ejector lever inward to lock the card after the screw is completely in the chassis.
Step 5 Use the Phillips screwdriver to fasten the captive screws.

  If the web pages cannot be displayed normally, your web browser may need an upgrade. For details about the web browser requirements, see the Web-based Configuration Guide of the switch.

The login page may differ slightly in different versions. Login Procedure

Step 1
Connect a PC to the device and the device enters the initial configuration mode.

(Mode 1)
Directly connect the PC to the ETH management interface to log in to the device for the first time. The default IP address of the ETH management interface on a device is 192.168.1.253/24. Directly connect the PC to the ETH management interface on the device using network cables.

(Mode 2)

Hold down the MODE button to log in to the device for the first time.

• If all interfaces on the device are optical interfaces, you need to connect the PC to the management interface using network cables. Press and hold down the MODE button for 6 seconds or longer. When all indicators on the device are steady green, the device enters the initial configuration mode, and the default IP address configured for the ETH management interface of the device is 192.168.1.253/24.
• If the device has Ethernet interfaces, connect the PC to any Ethernet interface excluding the ETH management interface using network cables. Press and hold down the MODE button for 6 seconds or longer. When all indicators on the device are steady green, the device enters the initial configuration mode, and the default IP address configured for Vlanif1 of the device is 192.168.1.253/24.

NOTE

• Users can log in to a device for the first time using the web system only when the device is in factory default state. In this case, do not log in to the device through the console interface, because any operation on the console interface leads to the failure of the first login using the web system.
• If you do not save the configuration in 10 minutes after entering the initial configuration mode, the system will exit from this mode and restore the factory settings.
• If the device in the factory settings has just started or has been configured through the console interface when users press and hold down the MODE button for 6 seconds, the device may fail to enter the initial configuration state. When all indicators blink fast for 10s, the device restores to the factory default state.
• If you have logged in to the device for the first time by holding down the MODE button for 6 seconds or longer and saved the configuration, default configurations of the ETH management interface are cleared and you cannot log in to the device for the first time through the ETH management interface. You are advised to preferentially log in to the device for the first time through the
• ETH management interface.

Step 2 Configure an IP address for the computer, which is in the same network segment as the default IP address of the switch.
Step 3 Start the web browser on the computer, enter https://192.168.1.253 in the address box, and press Enter to display the initial login page. The default username and password are available in S Series Switches Default Usernames and Passwords. If you have not obtained the access permission of the document, see Help on the website to find out how to obtain it.

NOTE

In V200R020C00 and later versions, the switch does not have a default web login password. You need to create a user name and set a password when logging in to the web system for the first time.

Step 4
Configure the switch. The web-based configuration page provides basic and optional configuration items. The basic configuration enables you to log in to the switch using the web system, and the optional configuration enables you to log in to the switch using Telnet or STelnet. Only parameters for the basic configuration are described below. For details about the optional configuration and more information about the product, see the Configur ation Guide for your switch on the Huawei support website.

Step 5 Click Apply to save the configuration. When you exit from the initial login page, either of the following situations will occur depending on the management IP address you configured:

• If the management IP address is in the same network segment as 192.168.1.253/24, the system jumps to the web login page directly.
• If the management IP address is not in the same network segment as 192.168.1.253/24, you cannot log in to the switch again using the web system. You need to configure another IP address for your computer to make the computer and switch reachable from each other.

The Quick Config function has been added to the web EasyOperation edition since V200R010. You can quickly finish the configurations of VLAN isolation and interconnection by selecting the Switching and Routing options.

Now, you can log in to the switch using the web system, Telnet, or STelnet to maintain the switch.\
