1. System clock not set
? E 0040 0000.0005
You can set the clock when you enter program mode (while the operating
system is running); see your operating system software documentation
for instructions.
2. Low battery
?
D 0050 0000.0005
The system battery's charge is low or completely discharged. Run the
system for about 17 hours to fully recharge the battery.
If you see single question marks on the power-up display, especially next
to a 7 or 6 (SCSI bus controller tests), but operation of the system seems
normal, continue to use the system. If you continue to see errors of this
type during the power-up display, use the information in the rest of this
chapter to solve the problems. See Section 6.6 for information on using the
system exerciser. If the system continues to display error information or
fails to operate normally, call your service representative.
A double question mark indicates a "hard" error. This indicates a serious
problem that may affect normal operation and use of some component of
the system. For example:
3. No Ethernet cable
?? 1 OOCO 0000.7004
This message indicates that the Ethernet subsystem is present in the
system, but that
• No cable is installed on the ThinWire/standard Ethernet connectors.
• No loopback connector on the standard Ethernet port.
• No terminator on the Thin Wire Ethernet port.
• Ethernet switch set to wrong position.
• Faulty cable.
