CHAPTER 12

Environmental Test (envtest)

---

envtest exercises the I2C bus on the Sun Enterprise 450 product line. envtest contains five subtests to test and report on the power supply status, system temperature status, fan speed, disk LEDs, and front panel and keyswitch. envtest is not scalable.

envtest Options

FIGURE 12-1 envtest

TABLE 12-1 envtest

envtest Options	Description
Disk LEDs Test	Illuminates each LED on the disk backplane(s) to green, then amber, and then back to its original state. The test then illuminates all disk LEDs to green, then amber, and then back to their original state. This test is only enabled in Functional test mode.
Fan Test	Cycles each fanbank speed to low, medium, and high, then verifies the correct speed. Next, each fanbank is stopped, one at a time. The test then verifies that a fan fault has occurred. Next, the watchdog timer is invoked to simulate a catastrophic failure. The test verifies that the system set all fanbanks to high and then resets the fan speed to normal. This test is only enabled in Functional test.

TABLE 12-1 envtest

envtest Options	Description
Front Panel and Keyswitch Test	Flashes each individual LED on the front panel to ON (green or amber), then OFF, and then back to its original state. The test then illuminates all front panel LEDs then sets them back to their original state. The power on LED is Read Only and will not be cycled. The test then displays the current keyswitch position. This test is only enabled in Functional test mode.
Power Supply Status	Identifies the number of power supplies that are in the system, and the state of each power supply, and verifies that the power supply temperatures are within normal operating parameters. This test is enabled in all modes.
Temperature Status	Identifies the current temperature of each CPU in the system, and the ambient temperature of the system, and envtest verifies that all temperatures are within normal operating parameters. This test is enabled in all modes.

envtest Test Modes

envtest supports Connection and Functional tests.

TABLE 12-2 envtest

Test Mode	Description
Connection Test	Reports the status of the power supplies, the temperature sensors within the system, and verifies normal operating parameters.
Functional Test	Tests the disk back panel, front panel LEDs, and fan control circuitry. Also uses the same functionality as Online mode and connection test If you invoke SunVTS through SyMON, the following Functional Test description applies: envtest runs in Connection Test mode (see description above).
