Inspect the media to see if there is visible damage. 4. Use another CD or DVD drive to check that the media is readable. 5. Check with other blade servers within the BladeCenter unit to see if they have the problem. If they do, the BladeCenter unit itself may be the cause of the problem. See the Problem Determination and Service Guide for your BladeCenter unit for more information. Network boot errors The following table describes the network boot errors. Table 13. Network boot errors Code Message Description Action E3000 (net) Could not read MAC address.
