General Devices

Third-Party Devices
If a third-party device does not work, it may be because the device is not supported
by your server or lacks up-to-date drivers.
•
Refer to your device and server -specific user documentation to be sure that your
server and operating system support the device.
•
Be sure that you have the latest device drivers. Refer to "Maintaining Current
Drivers" in Chapter 3.
Also, note which third-party board is installed into which slot because some
third-party PCI boards must be installed on the primary PCI bus.
Universal Serial Bus Devices
On some BL e-Series servers, connecting hot-plug universal serial bus (USB) devices
during POST can cause the server to fail to boot. If this is the case with your server,
wait until after POST to hot-plug your USB devices.
If you have a server that supports the Diagnostic Adapter and you are using USB
devices, refer to "Diagnostic Adapter" in this chapter for potential compatibility
issues.
Testing the Device
To test the device after checking device connections and support:
1. Uninstall the device.
Check whether the server works with the device removed and uninstalled. If it
does, that indicates a problem with the device, the server's support of the device,
or a conflict with another device.
2. If the SCSI device is the only device on its bus, check whether the bus works by
installing a different device on the bus.
3. Move the device to a different bus or PCI slot.
