Troubleshooting
This chapter helps you identify and solve problems that might occur
while you are using the system.
For any issue, first ensure that you are using the latest firmware and
files. Firmware upgrades include updates for BIOS, the BMC, and the
hot-swap controller. In addition to the server firmware and files, make
sure to update any drivers used for components you have installed in
your system, such as video drivers, network drivers and SAS drivers.
If you are unable to resolve your server problems on your own, contact
your dealer or local Acer representative for assistance.
