Turning the Power On after an Overtemp Shutdown

32
In the expansion enclosures, the overtemp indicator on the environmental status module
illuminates if the temperature reaches 40
overtemp indicator cannot come on. See Figure 3-3 on page 39 for the location of the overtemp
indicators on expansion enclosures.
The controller enclosure does not have an overtemp indicator. Check the storage management
software for temperature information about the controller enclosures.
To restart the enclosure after an unexpected shutdown due to an overtemp condition, follow these
steps:
1. Turn off both power switches (see Figure 3-1 on page 30).
2. Do whatever is necessary to cool the enclosure (replace the fans, use external fans to cool the
room, and so on).
Danger:
Severe electrical shock can occur. Never turn on the power to any equipment
when there is evidence of fire, water, or structural damage. If there is evidence of
damage, call the factory or appropriate service organization for assistance. Depending
on the current service agreements, you may need to send the unit back to the factory for
repair/replacement.
3. Check all components and cables for visible damage. Do not power on the enclosure if you
find evidence of damage.
Note: To speed drive spin-up, it is recommended that you start the expansion enclosures
before or at the same time as the controller enclosure.
4. Once the internal temperature is below 40
for the enclosure to power on.
5. Use TPSSM and the drive fault indicators (see "Checking the Indicator Lights" on page 36)
to check the overall status of the enclosure and its components. Repair any faults found.
