Verifying Proper Operation Of Key System Leds; Confirming Loading Of The Operating System; Kvm (Ps/2 Keyboard-Video-Mouse) Unit Causes System To Hang During Post - Sun Microsystems Sun Fire V60x Manual

During POST, the server BIOS presents screen messages to indicate error conditions.
POST also provides beep codes to give you audible clues regarding the performance
and operation of the server when there is no video display that can present error
messages. In addition, a set of four bi-color diagnostic LEDs is located on the back
edge of the server main board. These LEDs are active during POST and indicate the
state of the server. Each of the four LEDs can have one of four states: Off, Green,
Red, or Amber. See "Power-On Self Test (POST)" on page 3-15 for a complete
description of the screen messages, beep codes, and diagnostic LEDs.
2.2.1.7

Verifying Proper Operation of Key System LEDs

As POST determines the system configuration, it tests for the presence of each mass
storage device installed in the system. As each device is checked, its activity light
should turn on briefly. Check to see if the disk drive activity light for each drive
turns on briefly. If not, see "Disk Drive Activity Light Does Not Light" on page 2-12.
2.2.1.8 Confirming Loading of the Operating System
Once the system boots up, an operating system prompt similar to the one shown
below appears on the screen (this example is for Linux):
Linux release x.x
Kernel 2.4.931enterprise on an i386
<hostname> login:
The prompt varies according to the operating system. If the operating system
prompt does not appear, see "Loading the Operating System" on page 4-16 or
"Recovering the BIOS" on page 4-53, or "Processor and Heatsink Configurations" on
page 1-6.
2.2.1.9 KVM (PS/2 Keyboard-Video-Mouse) Unit Causes System To
Hang During POST
Some KVM switches may cause intermittent problems during Power-On Self Test
(POST). Possible issues are as follows:
The system may not respond to keyboard or mouse inputs.
■
The system may hang, causing the watchdog timer to expire. This in turn causes
■
a FRB-2 (Fault Resilient Booting) event. By default, if a FRB-2 event occurs (on
redundant processor systems), the Boot-Strap-Processor will be disabled on the
next boot.
