3 Switch Unit (SU1)
RTC
The real time clock has backup for short power b r eaks. The tim e is kept for at least 20 hours (at
20º C/68º F).
A/D Converter
There is an analog to digital converter on the baseboard. It is used for measuring a nd monitoring
operating voltages and temperatures.
3.3.2 FPGA Subsystem
The FPGA subsystem implements the switch m atrix fu nctionality for the NE at 900 Gbps.
3.3.3 Control Ethernet Switch
The control Ethernet switch is used f or NE internal communication and it is fully separated from
the normal data plane.

3.3.5 Power Supply
SU1 contains an integrated power supply (DC/DC converters) on board. It generates all t he voltages
which are needed within diff
erent blocks. The input voltag e is fed by either of the PIM s (redundancy
with two PIMs). The generated output voltages are galvanically isolated from the bat tery voltage.
SU1 has a polarity protection for wrong polarity.
3.3.6 Test Features
During boot-up, SU1 performs self tests to verify that the system operational status is nominal.
During normal oper
ation, the CPU m onitors the following:
• SU1 operatin g voltages.
• Temperature inside SU1.
