1. Introduction
Switch stacking technology is a network solution that enables network switches to be connected together as a single unit with the same
IP address. Set up as a single entity, stackable switches have not only optimized scalability and flexibility but also simplified network
configuration and administration. FS S3900 series stackable switches, which are designed for the campus network, SMB, and home
network, have the ability to stack as well.
2. Topology
3. Configuration Steps
3.1 Connect the Device
Connect the PC and the switch to the network cable and the console port. Connect one end of the RJ-45 network cable to the network
card interface of the PC and the other end to the network port of the SW. Connect one end of the console cable USB to the USB port of the
PC. One end of the RJ-45 is connected to the console port on the front panel of the switch.
3.2 Download the Configuration Software
After the connection is complete, here we recommend HyperTerminal, putty or SecureCRT tools to configure the switch.
3.3 Open the Switch and Use the Login Software
Power on the switch, then open the installed login software, select the serial login mode, Port is determined by the device manager, Baud
rate: 115200, Data bits: 8, Parity: None, Stop bits: 1.

NOTE: You can view the COM Number via Device Manager (right-click My Computer > Administration > Device Manager > Ports (COM
and LPT). If an unrecognized USB device is displayed, download and install the corresponding driver.
3.4 Log in to the Switch
After completing the above steps, hitting the Enter key of the keyboard will prompt you to enter the account password. At this time, enter
the default username and password admin/admin to log in to the switch.
3.5 Configuration
(1) Turn on the stacking function of two S3900-24T4S switches.
S3900-24T4S-A(config)#stacking enable 1
S3900-24T4S-B(config)#stacking enable 1
(2) Save configuration and then restart the two switches.
S3900-24T4S-A#copy running-config startup-config
S3900-24T4S-A#restart
S3900-24T4S-B#copy running-config startup-config
S3900-24T4S-B#restart
(3) Check the status of the master switch. S3900-24T4S-A is the master switch and S3900-24T4S-B is the slave switch. Users cannot log
in to the slave switch when the master switch is in management.

(5) Configure the eth1/21 port and eth 2/21 port as access on the master switch and allow VLAN 10 pass.
Switch(config)#interface ethernet 1/21
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config)#interface ethernet 2/21
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
(6) Configure IP address 10.100.10.4 and mask 255.255.255.0 for the PC.
(7) Connect PC with the eth1/21 of master, and ping VLAN 10 IP address on PC.

(9) PC can successfully ping master switch and slave switch, suggesting switch stacking is accomplished.
3.6 Matters Needing Attention
It should be noted that the FS S3900 needs to use the last two 10G SFP + ports for stacking. The stacking ports are hidden during stacking,
but all the hidden ports can be seen on the main device. The maximum support is 6 stacks. For multiple stack connections, please refer to
The following figure.
