Leds After Self-Test - DEC AlphaServer 8200 Installation Manual

Processor and memory modules have a green LED that lights when the
module passes or completes self-test. These LEDs can be viewed through
holes in the shield of the module enclosure from the front of the cabinet.
PCI I/O modules are not visible but some connectors have LEDs on them.
Table 6-1 lists TLSB and DWLPA, the PCI motherboard, modules showing
LED conditions after self-test. For the conditions of LEDs on PCI and
EISA devices/adapters, see the related documentation.

1 The green LED on the processor module indicates that a single CPU chip on a uni-
processor module passed self-test or both CPU chips on a dual-processor module passed.
The LED will be OFF if there is any failure on the module though it may be configured
into the system.
2 The green LED on the memory module indicates that self-test completed, not passed.
3 The DWLPA, the PCI motherboard, has four LEDs. The self-test passed LED is the sec-
ond from the hose connection.
