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 master controller card, loop processor cards, IO cards and network cards. It 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 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.
