Environmental errors
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)
Displaying the CUB LED values using pce
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:
$
sppdsh
Step 2. Use the
pce
command to display the LED values for all nodes, enter:
sppdsh:
pce all
Node IP address Clocks LEDS @C U SHPT Supply1 Supply2 Supply3 Supply4

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” .
