3.5 Additional Fabric Extension Module (PCB4)
PCB4 also serves as a fabric extension module of PCB1. However, the actual dimen-
sions and limitations of the module will heavily depend on the PCB3 implementation.
So, PCB3 and PCB4 should always be considered as a common set.

3.6.1 MCMC LED Indicators
Although the uTCA specification still mandates four LEDs, UTCA-5503 implementa-
tion follows the latest AMC.0 specification.
3.6.2 Handle Switch
A handle switch is implemented to support the hot swap function of the MCMC. The
handle switch type and location are designed according to the MicroTCA base speci-
fication.
3.6.3 Mini USB
The USB port is used for debugging, diagnostic information and implementation of a
serial console interface.
3.6.4 Reset Button
The reset button at the front panel is used for resetting the MCMC.
