recover the system and data might be lost. Keep the temperature within the normal operating range if
possible, and maintain a reliable power supply.
To extend the operational temperature range of all enclosures in the system to meet NEBS operating
temperature requirements, enter the following CLI command:
chsystem -hightempmode on
After it is set, high_temp_mode is applied to all enclosures in the system.
To congure the default operating temperature ranges, enter the following CLI command:
chsystem -hightempmode off
To determine which mode is congured, read the value of the high_temp_mode parameter in the
lssystem output.
Notes:
1. Conguring the system to be NEBS-compliant only changes the way that the system responds to
raised temperature. You must also ensure that the way the system is racked, and the operating
environment, conforms to NEBS requirements. See “NEBS-compliant earth connection” on page 23.
