DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch 

The Upgrade to v1.6 

To better improve SIM management, the  DES-3028/28P/52/52P Switches have been upgraded to version 1.6 in this release. 

Many improvements have been made, including: 

1.  The Commander Switch (CS) now has the capability to automatically rediscover member switches that have left the SIM 

group, either through a reboot or web malfunction. This feature is accomplished through the use of Discover packets and Maintain 

packets that previously set SIM members will emit after a reboot. Once a MS has had its MAC address and password saved to the 

CS’s database, if a reboot occurs in the MS, the CS will keep this MS information in its database and when a MS has been 

rediscovered, it will add the MS back into the SIM tree automatically. No configuration will be necessary to rediscover these 

switches. 

There are some instances where pre-saved MS switches cannot be rediscovered. For example, if the Switch is still powered down, 

if it has become the member of another group, or if it has been configured to be a Commander Switch, the rediscovery process 

cannot occur. 

2.  The topology map now includes new features for connections that are a 

member of a port trunking group. It will display the speed and number of Ethernet

connections creating this port trunk group, as shown in the adjacent picture. 

3.  This version will support multiple switch upload and downloads for firmware, configuration files and log files, as follows: 

•  Firmware – The switch now supports multiple MS firmware downloads from a TFTP server. 

•  Configuration Files – This switch now supports multiple downloading and uploading of configuration files both to (for 

configuration restoration) and from (for configuration backup) MS’s, using a TFTP server.. 

•  Log – The switch now supports uploading multiple MS log files to a TFTP server. 

4. The user may zoom in and zoom out when utilizing the topology window to get a better, more defined view of the 

configurations. 

SIM Settings 

All switches are set as Candidate (CaS) switches as their factory default configuration and Single IP Management will be disabled. 

To enable SIM for the Switch using the Web interface, go to the Single IP Settings folder, located in the Administration folder, 

and click the SIM Settings link, revealing the following window.
