Page 29 User’s Manual of GS-5220-16S8C & GS-5220-16S8CR  Approved PLANET SFP Transceivers PLANET Managed Switch supports both single mode and multi-mode SFP transceiver. The following list of approved PLANET SFP transceivers is correct at the time of publication: Fast Ethernet Transceiver (100Base-X SFP)
Page 30 1310nm -40 ~ 75 ℃ 1. It is recommended to use PLANET SFP on the Managed Switch. If you insert an SFP transceiver that is not supported, the Managed Switch will not recognize it. Before we connect the GS-5220-16S8C/GS-5220-16S8CR to the other network device, we have to make sure both sides of the SFP transceivers are with the same media type, for example: 1000Base-SX to 1000Base-SX, 1000Bas-LX to 1000Base-LX.
Page 31 User’s Manual of GS-5220-16S8C & GS-5220-16S8CR  Remove the Transceiver Module Make sure there is no network activity anymore. Remove the Fiber-Optic Cable gently. Lift up the lever of the MGB module and turn it to a horizontal position. Pull out the module gently through the lever.

It describes the types of management applications and the communication and management protocols that deliver data between your management device (workstation or personal computer) and the system.
Page 33: Management Access Overview
User’s Manual of GS-5220-16S8C & GS-5220-16S8CR 3.2 Management Access Overview The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:  An administration console  Web browser interface  An external SNMP-based network management application The administration console and Web browser interface support are embedded in the Managed Switch software and are available for immediate use.
Page 34: Administration Console
User’s Manual of GS-5220-16S8C & GS-5220-16S8CR 3.3 Administration Console The administration console is an internal, character-oriented, and command line user interface for performing system administration such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal, personal computer, Apple Macintosh, or workstation connected to the Managed Switch's console (serial) port.
Page 35: Web Management
User’s Manual of GS-5220-16S8C & GS-5220-16S8CR You can change these settings, if desired, after you log on. This management method is often preferred because you can remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, regardless of the interface through which the associated action was initiated.
Page 36: Snmp-Based Network Management

This Managed Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains.
Page 106 User’s Manual of GS-5220-16S8C & GS-5220-16S8CR ■ 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Page 107 User’s Manual of GS-5220-16S8C & GS-5220-16S8CR Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN are defined on the switch, all ports are then assigned to a default VLAN with a PVID equal to 1. Untagged packets are assigned the PVID of the port on which they were received.
