The Temperature Sensors panel shows the current temperature for the various array controllers and processors, in
addition to the normal temperature range. Table 15-16 describes the array temperature status, descriptions, and how
to solve any issues.
Table 15-16: Array Temperature Status
Status Description Solution
normal Temperature is within normal range. None needed; informational.
warning Temperature is outside normal range, but within
lim
its.
Check
that all fans are working properly. Monitor the
temperature carefully.
critical Temperature is outside operating limits. Check that all fans are working properly.
Make sure the
air conditioning system is working correctly, and make
sure there is air flow around the array. If a processor
temperature stays high, replace the control module.
See your PS Series support provider for information
abou
t replacing
a failed cooling module.
Multiple fan failures increase the array temperature. A high temperature results in event messages. The array might
shut down before damage occurs.
Some PS Series arrays also show the ambient temperature, which is calculated in Celsius from
the two sensor
temperatures with the highest temperatures, using the following formula:
((Backplane Sensor 0 + Backplane Sensor 1) / 2) – 7
Monitoring channel cards
Some array models include redundant channel cards. An array continues to operate if a channel card fails. You can
replace the failed channel card with no impact on group operation.
Table 15-17 shows channel card status, descriptions, and how to solve any issues.
