11.2 Checking the LED Display
Table 11–1 shows you how to interpret the LED display codes. The codes are
shown in the order in which the tests run, so you can determine which subtests
ran successfully and at what point the test failed.
If the LED display indicates a problem with your workstation, try the
suggestion provided for that LED code. If no specific suggestion is given, or if
the suggested procedure does not solve the problem, try reinstalling the CPU
module and the memory modules on the base system module. Then restart the
workstation. If the problem persists, call your system manager or the Digital
Customer Support Center.
Table 11–1 Interpreting the LED Codes
LED
Code
Meaning
Workstation hardware initialization could not begin.
Workstation firmware initialization could not be completed.
Firmware could not initialize the input-output subsystem on the system
module to a known state. The input-output subsystem controls the Ethernet
and SCSI interfaces, as well as the keyboard, mouse, and other serial-line
communications.
Memory slot 0 could not be initialized. Try replacing the memory module in
memory slot 0 (see Chapter 9 ).
Firmware could not calculate the cache size. Try reinstalling the CPU module
(see Chapter 9 ).
Firmware could not calibrate the millisecond delay loop. Try reinstalling the
CPU module (see Chapter 9 ).
Firmware could not configure the system. Try reinstalling the CPU module
and all memory modules (see Chapter 9 ).
If the workstation turns on, all workstation components have been initialized,
and the workstation is ready for use.
If the workstation does not turn on,
a device or module is not connected properly or is broken. Make sure that
all cables are securely attached and that all external components of the
workstation have been installed properly and are plugged into a power source.
