272 Chapter 6. Managing the Router
If the date is set to zero, the real-time clock is disabled for long-term storage.
The time and date fields are overwritten by the GUI, when the router is configured by a PC. The time and
date values are then read from the PC.
Option 7: Set Console Baud Rate
Select option 7 to alter the baud rate that is used by the router to communicate over the Console port with the
terminal-emulation program. You can override the default rate of 9600. Remember to set the identical baud
rate in your terminal emulation program.
Option 8: Start Extended Diagnostics
Manual boot mode allows you to run extended diagnostics. You may want to run extended diagnostics if you
suspect a hardware problem. If you select option 8 from the main boot-procedure menu, you will see the
following display:
[1] DRAM test
[2] Parity test
[3] POST firmware CRC test
[4] Real-Time Clock chip test
[5] Timers and Interrupts test
[6] Multi-port UART (internal loopback) test
[7] Multi-port HDLC (internal loopback) test
[8] SCC2 External Loopback test
[9] SCC3 External Loopback test
[a] SCC4 External Loopback test
[b] Ethernet Transceiver (internal loopback) test
[-] Deselect all tests
[+] Select all tests
[.] Run selected tests
[#] Enter debugger
[/] Exit extended diagnostics (reboot)
Enter the number of each test that you would like to run, or select all tests. Then enter Ò.Ó to begin diagnostic
testing. (All of the tests automatically run when you power up or reboot the router.) A debugging mode is
available for use primarily when you encounter a serious problem, in consultation with customer support
services.
Boot diagnostics are only available on routers with the MC68EN360 processor.
