Once the stack cable is connect to the stack port of each SGS-5220 Series switch and power on them, the stack is builded automatically and the Switch ID is automatically assigned to the switch.
  • Page 354 User’s Manual of SGS-5220 Series Step 1: linking the switches by CB-DASFP-0.5M stack cable. Step 2: Check the Master LED of each SGS-5220 Series switch to find out the Master Switch that is elected automatically by the stack operation. Step 3: Use the Web browser such as IE 7.0 to login the Master Switch, the default IP address is 192.168.0.100. Or you can use the PLANET Smart Discovery Utility to find out the IP address of the stack group.

The slave IP address can be the same as Master IP address. Thus, if master switch is malfunctioned, you can still access the other switch by the same IP address.

    User’s Manual of SGS-5220 Series 5. SWITCH OPERATION 5.1 Address Table The Managed Switch is implemented with an address table. This address table is composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port number, etc. This information comes from the learning process of Managed Switch.

    User’s Manual of SGS-5220 Series load on the network. The Managed Switch performs "Store and Fforward"; therefore, no error packets occur. More reliably, it reduces the re-transmission rate. No packet loss will occur. 5.5 Auto-Negotiation The STP ports on the Switch have built-in "Auto-negotiation". This technology automatically sets the best possible bandwidth when a connection is established with another network device (usually at Power On or Reset).
