6.2 SCSI Backplane Configuration Jumpers
The following table describes the settings and functionality of the jumper block used on the
SR1300 hot-swap SCSI backplane.
Table 19. Hot-Swap Backplane Configuration Jumpers
Option Location Description
Firmware Update J4 Placing this jumper in the “FORCE UPDATE” position forces external
firmware update of the program code stored in Flash memory. Placing this
jumper in the “NORMAL OPERATION” position allows normal operation
Flash Boot Block Write J4 This jumper allows the boot block of the program flash to be updated.
“NORMAL OPERTATION” (default) does not allow the boot block to be
written to. “WRITE” allows updating of the boot block
6.3 SCSI Backplane Functional Architecture
Functionality of the SCSI backplane begins at power-up. The microprocessor boots up via code
residing in the flash boot block. The SCSI backplane is capable of downloading firmware via
the IMB in-order to update the flash executable code.
The following figure shows the functional blocks of the hot-swap SCSI backplane.
