4-2.2 Power On Self Test (POST) Diagnostics
Power-on self tests (POST) are optional diagnostics designed to exercise the hardware cards and modules, to the
component level, in order to detect and report any problems.
POST diagnostics are currently run upon start-up on the T1 card, and can be invoked off-line for both the T1 and TRX
cards. The following section describes the recommended sequence of steps which should be performed in order to
check that the Craft PC can be connected to the BTS over an Ethernet connection, that the correct version of code is
loaded from the Craft PC to the BTS and that the POST diagnostics are run successfully.
