Siemens KVM series 3-1621 manual Virtual media, Repairing damaged firmware

5.1.3Repairing damaged firmware

In the rare case that the firmware is damaged after a firmware upgrade (which might happen if the KVM s3-1621 or KVM s3-1641 appliance is turned off and turned on during the upgrade process), the KVM s3-1621 or KVM s3-1641 appliance will remain in boot mode. In this mode, the Power LED on the rear panel flashes at about 1 Hz, and the KVM s3-1621 or KVM s3-1641 appliance attempts to restore the firmware over TFTP using the following default configuration:

•TFTP client IP address 10.0.0.2

•TFTP target device IP address 10.0.0.3

•Upgrade the file name to CMN-1016.fl. To repair damaged firmware:

Connect the KVM s3-1621 or KVM s3-1641 appliance to the TFTP target device (using a cross-over cable or hub), which is set up with the default IP address (10.0.0.3).

Rename the upgrade file to the default file name (CMN-1016.fl).

The Power LED will flash at about 2 Hz when the KVM s3-1621 or KVM s3-1641 appliance is downloading the upgrade file, and it will flash at about 4 Hz when it is programming the downloaded file to Flash. After it has restored the firmware, the KVM s3-1621 or KVM s3-1641 appliance reboots automatically and the Power LED illuminates.

5.2Virtual media

5.2.1Virtual media and USB 2.0 constraints

The virtual media feature of the KVM s3-1621 and KVM s3-1641 appliances enables you to connect to the USB port of an attached computer. With this feature, a user located at a KVM s3-1621 or KVM s3-1641 appliance or using the remote software can access a local USB storage switch, such as a USB CD drive, diskette drive, or Flash drive, from an attached computer.

The Virtual Media KVM-IA addresses four functions: keyboard, mouse, CD drive, and mass storage unit. The CD drive and mass storage unit will be present on the target server whether or not a virtual media session is mapped. If a media device is not mapped, it is shown without media present. When a virtual media device is mapped to the target server, the target server will be notified that media has been inserted. When the media device is unmapped, the target server will be notified that the media was removed. Therefore, the USB virtual device is not disconnected from the target server.

The KVM-IA presents the keyboard and mouse as a composite USB 2.0 device. Therefore the BIOS must support composite USB 2.0 human interface device (HID). If the BIOS of the connected computer does not support this type of device, the keyboard and mouse might not work until the operating system loads USB 2.0 device drivers. If this occurs, there might be a BIOS update provided by the computer manufacturer that will provide BIOS support for a USB 2.0 connected keyboard and mouse.
