be run from the terminal; a passcode and unit ID may be set
using the UTIL menu.
Upon a power-up, the Test LEDs are illuminated and the

When . . .
the self-test is complete
with no failures detected

The full self-test procedure (invoked from a terminal or
T-Watch Pro) consists of the following tests:
Board level tests
Each of the TSU 610 boards contains an on-board processor
which executes a series of tests checking the circuitry on the
board.
•
RAM and EPROM tests
•
Verify on-board circuitry
Unit level tests
•
Front panel LED verification
•
Board-to-board interface test
A test pattern is sent from the controller through a loopback

verifies the data path, clocks, and control signals for the
entire chassis.
