Diagnostic Tests
Startup power-on self test (SPOST) and power-on self test (POST) diagnostic tests run
automatically on the LN1000-V Mobile Secure Router as part of the boot-up process at
every poweron, 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.

LN1000-V Mobile Secure Router Status LED
Upon initial power-on, the components of the router run boot code, go through a series
of self-diagnostic tests, and synchronize with each other. When the tests are complete,
use the LED on the router front panel to determine the status of the router.
