Description
1
Fixed Part Program
Flash Program
System Parameters
Flash Memory
(and backup FD)
The parameters are stored in flash memory. No
provision of storage against a power shut off is
required for the parameters because flash memory can
retain information when power is shut off.
Parameters can be backed up to the following:
Fixed part program: N/A.
Flash program: Automatically backed up to the
system area.
System parameters: Automatically backed up to the
disk drive.
2 Microprogram
Configuration Information
SNMP Information
Disk Drive (System Area)
Generally, information in a RAM is erased when the
main switch is turned off. Therefore, the subsystem
also stores the parameters used on the RAM on the
disk drive. (An area is reserved in the disk drive to
store them. This area is called the system area.)
The system area is provided on the disk drives #0 to #4
in the RKXS frame. Therefore, the system area has
redundancy for disk drives #0 to #4 in the RKXS frame.
