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
