7.2.1 Field Replaceable Unit (FRU)
The ATA backplane uses a Dallas* DS1624 to save board specific data, including serial
number. This is attached to the I
2
C bus of the front panel.
7.2.2 Power Control Logic and Driver
Although the ATA backplane does not support hot swapping of hard drives, the backplane
provides power control logic that reduces the chance of damage to a hard drive, should
someone attempt to remove or insert a drive while the system is powered on.
Only cold swapping of drives, (i.e., system must be powered off before the ATA drives or the
floppy/CDROM module can be inserted or extracted from the system) will be supported in the
server chassis SR1300.
7.2.3 Server Boards SE7500WV2 and SE7501WV2 to CD/FDD/FP Interface
The ATA backplane provides a pathway for signals from the 100-pin floppy/FP/IDE connector to
the high-density FDD/CD daughter board connector and the FP connector. The following table
provides the pinout for the 100-pin (JAEE*: WR-100S-VF-1) connector.
