Throughout this document, the caution icon ( ) is used to indicate cautions and precautions that you need to review and follow.
Page 11: General Precautions For Rack-Mountable Products
DES-1228/ME Layer 2 Metro Ethernet Managed Switch • To help protect your system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS). • Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. Be sure that nothing rests on any cables.
Page 12: Protecting Against Electrostatic Discharge
DES-1228/ME Layer 2 Metro Ethernet Managed Switch CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to connect power to the system until grounding cables are connected. A qualified electrical inspector must inspect completed power and safety ground wiring. An energy hazard will exist if the safety ground cable is omitted or disconnected.

Page 99: Ism Vlan Settings
DES-1228/ME Layer 2 Fast Ethernet Managed Switch ISM VLAN Settings In a switching environment, multiple VLANs may exist. Every time a multicast query passes through the Switch, the switch must forward separate different copies of the data to each VLAN on the system, which, in turn, increases data traffic and may clog up the traffic path.
Page 100 DES-1228/ME Layer 2 Fast Ethernet Managed Switch Enter a name for the ISM VLAN into the VLAN Name field and choose a VID between 2 and 4094. Entries in these two fields must not have been previously configured on the switch or an error message will be prompted to the user. Once these two fields have been filled, click the Apply button, which will automatically adjust the current window to resemble the following window.
Page 101: Spanning Tree
This Switch supports three versions of the Spanning Tree Protocol; 802.1d STP, 802.1w Rapid STP and MSTP. 802.1d STP will be familiar to most networking professionals. However, since 802.1w RSTP has been recently introduced to D-Link managed Ethernet switches, a brief introduction to the technology is provided below followed by a description of how to set up 802.1d STP and 802.1w RSTP.
Page 102: Port Transition States
DES-1228/ME Layer 2 Fast Ethernet Managed Switch The IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1d STP standard. RSTP was developed in order to overcome some limitations of STP that impede the function of some recent switching innovations, in particular, certain Layer 3 functions that are increasingly handled by Ethernet switches.
Page 103: Stp Bridge Global Settings
Yet, even this function can malfunction with the emergence of STP BPDU packets that occasionally loopback to the Switch, such as BPDU packets looped back from an unmanaged switch connected to the DES- 1228/ME. To maintain the consistency of the throughput, the DES-1228/ME now implements the STP LoopBack prevention function.
