upward.
Is there any soil or crack on DVD/CD-ROM disk?
→ Make sure there is no soil due to fingerprint or others on the disk surface. Also
make sure that there is no crack on the disk surface. Clean the disk surface if it is
soiled. If read-out still fails, set another disk of which data has been successfully
read out to check if the drive can read the disk.
Is the DVD/CD-ROM disk in closed status?
→ Close the session or set the disk in closed status, and try to read again.
The system does not restart automatically when an error occurs, though the system is
adjusted to automatic restarting:
→ When the system does not restart automatically, restart it manually.

protocol, such as TCP/IP, and services are properly specified.
Is the transfer speed correct?
→ The internal LAN controller can accept the link speed of 1Gbps, 100Mbps, or
10Mbps. You can select a link speed from OS, however, do not use [Auto Detect]
feature. Specify the "Link Speed & Duplex" value the same as the value specified
for HUB. If you use the Wake On LAN feature, specify [Auto] for "Link Speed &
Duplex".
