Lattice CPLD onboard the TN48M switches is used for system
|
||
|
|
management.
|
||
|
|
|
||
|
|
It provides information about the hardware model, revision,
|
||
|
|
PSU status etc.
|
||
|
|
|
||
|
|
It is also being used as a GPIO expander and reset controller
|
||
|
|
for the switch MAC-s and other peripherals.
