HP (Hewlett-Packard) 9000 V2500 SCA ユーザーズマニュアル

Indicators, switches, and displays

Environmental errors are detected by two basic systems in the V2500/
V2600 server: Power-On and Environmental Monitor Utility Chip 
(MUC).

Power-On detected errors such as ASIC install or ASIC not OK are 
detected immediately and will not allow dc power to turn on until that 
condition is resolved.

MUC detected errors such as Ambient Air Hot allows the dc power to 
turn on for approximately 1.2 seconds before the dc power is turned off. If 
two or more fans fail simultaneously, the MUC will shut off dc power. 
Other MUC detected errors such as Ambient Air Warm will flash the 
LED and not turn off dc power.

Error codes may be viewed by using the SSP utility command 

pce

 to 

read the status of the CUB. However, this feature will only work after 
database generation is complete, not before.

Using the SSP utility man leds to decode the CUB status nibbles.

The current environmental temperature set-points are:

• Warm = 32 degrees Celsius (89.6 degrees Fahrenheit)

• Hot = 37 degrees Celsius (98.6 degrees Fahrenheit)

Use the 

sppdsh

 command 

pce

 to display the value of the LEDs on the 

CUB. 

Step 1. Bring up the 

sppdsh

 prompt at a sppuser window by entering:

$

 

Step 2. Use the 

pce

 command to display the LED values for all nodes, enter:

sppdsh:

 

Node     IP address Clocks      LEDS   @C U SHPT Supply1 Supply2 Supply3 Supply4

------------------- ------ --------- ---- ------ ------- ------- ------- -------

  0   15.99.111.116 Normal   0x00      25 1 0000 Nominal Nominal Nominal Nominal

  2   15.99.111.117 Normal   0x00      25 1 0000 Nominal Nominal Nominal Nominal

For more information about the 

pce

 command see the sppdsh man page.

Step 3. Decode the LED values using Appendix A, “LED codes” .
