Write protect link on backplane
The backplane assembly is fitted inside the left side of the backbox.
The backplane has the card slots to facilitate interconnection of plug-in cards, such as the Main
Controller Card (MCC), Loop Processor Cards, IO Cards and Network Cards.

Protected
- write protected
Unprotected
- not write protected
(factory setting)
The backplane also has the flash memory
(NVM) which is under the control of MCC and
is a shared memory to which the system
configuration data is saved.
The link header on the backplane marked
LK1 provides 'write' protection and will stop
the SAVE and BACKUP commands from the
panel controls modifying the memory.
Once the system is fully commissioned the
link LK1 should be configured to 'write
protected', this is important on sites where
customers require compliance to the EN54
Part 2 standard.
The NVM should always hold the complete
system back up.
