HP USB Virtual Media Interface Adapter

Functionality Information

Using Virtual Media

HP recommends the HP USB Virtual Media Interface Adapter (model AF603A) only for computers that do

not have PS2 keyboard and mouse support. HP recommends the HP PS2 Virtual Media Interface Adapter

(model AF604A) for computers that have PS2 support.

Before installing the HP USB Virtual Media Interface Adapter on an existing server, confirm that the server

BIOS is upgraded to the latest version.

For Virtual Media to function properly, you must have the following components:

• One interface adapter with Virtual Media for each server or device

• HP USB Virtual Media Interface Adapter

• HP PS2 Virtual Media Interface Adapter

• Console switches with Virtual Media

• HP IP Console Switch with Virtual Media

• HP Server Console Switch with Virtual Media

Virtual Media functionality will not work properly if you do not have a Virtual Media KVM switch or a

Virtual Media interface adapter or if a Port Expansion Module is installed between the server and the

Virtual Media KVM switch.

Composite device functionality

The HP USB Virtual Media Interface Adapter is a composite high-speed USB 2.0 device by default, and

as a composite device, it enumerates all devices that it represents at the same time, not individually. Any

change to the devices it represents will initiate a hot-plug event ("Hot-plug events" on page 2).

On power up, the interface adapter presents a keyboard, a mouse, and the last media device that was

mapped, or the CD-ROM drive by default. Though the interface adapter can support two media devices

simultaneously, it will not present both devices from power up.

This setup enables one media device to be functional at all times, with hot-plug events only triggered

when you change the type of virtual media mapped. Both Virtual Media devices are only functional when

you concurrently map both devices. Depending on the server configuration of mapped drives, the interface adapter recognizes that: • Neither of the media drives are mapped. ("Neither of the media drives are mapped" on page 2) • A mass storage device is mapped. ("A mass storage device is mapped" on page 2) • Both of the media drives are mapped. ("Both of the media drives are mapped" on page 2) If the server does not support USB 2.0 at the BIOS level or in the operating system: 1.

USB compatibility Because of incompatibilities in various combinations of USB chipsets, composite USB support in serverclass computers, and variances in USB device implementations, issues might arise when attempting to boot from a USB device directly connected to the server when an HP USB Virtual Media Interface Adapter is connected to the server or when using a remote Virtual Media session through the HP IP Console Viewer. In such cases, use a different model or manufacturer of the USB device.

Current or previous selection in the interface adapter Current mapped drives Action Result CD-ROM CD-ROM A mass storage device and a CDROM drive are mapped. The interface adapter disconnects from the USB bus and then reconnects to the USB bus. When the server accesses the interface adapter, it reports a keyboard, mouse, CD-ROM drive, and a generic removable media device. CD-ROM CD-ROM A mass storage device is mapped, and a CD-ROM drive is not mapped.

Current or previous selection in the interface adapter Current mapped drives Action Result Mass storage and CD-ROM Mass storage and CD-ROM Either the mass storage device or the CD-ROM drive is not mapped. The interface adapter triggers a USB hot-plug event to the server. When prompted by the server BIOS, the interface adapter reports that the device is still mapped. © Copyright 2006 Hewlett-Packard Development Company, L.P.
