    SPOST and POST Diagnostic Tests

    Startup power-on self test (SPOST) and power-on self test (POST) diagnostic tests run automatically on the LN1000 Mobile Secure Router as part of the boot-up process at every power on, reset, or warm reboot.

    • SPOST diagnostics consist of a limited suite of quick diagnostics that ensure that system components required for Boot Loader and diagnostics relocation and execution from RAM are working without error.
    • POST diagnostics consist of a suite of quick diagnostics that ensure that components of the system are working without error before trying to load and execute Junos OS.

    PASS/FAIL test results for the SPOST and POST diagnostics are reported by means of the front panel LED, console port, and IPMI.

    In the event that SPOST, POST, or the bootstrap sequence reports a failure and the front panel LED lights red, extended diagnostic tests are available. For information about running extended diagnostic tests, contact Juniper Networks at http://www.juniper.net/in/en/contact-us/.
