FRONT PLATE ELEMENTS
The TPU-1 terminal has twenty-five LEDs on the front plate. The LEDs identified as
PRIMARY and SECONDARY are associated with the terminal power supply. The
PHYSICAL LINK LEDs indicate the interface type being active, and the LEDs identified as
TP 1 and TP2 are associated with the two possible communication channels that can
manage the terminal and to the command transmission and reception circuits.
The front plate also has an USB connector that is for Pweb management
(1)
. It can also have
an optional LCD display which allows certain parameters of the terminal to be monitored,
see
Appendix D,
without having to access the Management System.
Figure 3 and Figure 4 show the signalling of the different LEDs, and Figure 5 describes the
optional LCD display.

the terminal, is known as External Web Management.
