58OSD OperationUpgrade AdaptersIn addition to upgrading the KVM firmware, the Maintenancesection allows you to upgrade the firmware of the connectedSIUs. The firmware upgrade file for the master KVM alsocontains the firmware for the SIUs, so you do not needseparate files for each SIU. Once you have uploaded themost current KVM firmware, the most current SIU firmware isavailable via the Upgrade Adapters sub-section.Note: Only those SIUs that are directly connected to the master KVMswitch can be upgraded. SIUs that are connected to cascaded KVMs willnot be upgradeable via the master KVMs Maintenance section.To upgrade the firmware to the connected SIUs, follow thesteps below.1. Logon to the OSD, and navigate to the Maintenance section,which will open with the Upgrade Main Firmware sub-sectionpage displayed.

By default, the Check Adapter Firmware Version box is checked, which causes the KVM to check to see if the current firmware is newerthan that of the firmware file you are using to upgrade the SIUs. If the current version is newer, you will not be allowed to continuewith the upgrade. If you wish to perform a firmware upgrade without checking to see if the current firmware version is newer thanthe upgrade file, simply uncheck this checkbox.3. Click the Adapter Firmware Info button to display the most current SIU firmware versions available on the KVM switch. Compare thisinformation with the firmware version numbers displayed in the Upgrade Adapters list.
