7. ATA Backplane
The server chassis SR1300 can support a multifunctional ATA backplane, supporting the
following features:
• Two cold swappable ATA hard drive connectors
• One floppy/CDROM or floppy/DVDROM module interface connector
• Hard drive power-up control logic
• Pathway for signals from the 100-pin floppy/FP/IDE connector to the 60-pin
floppy/CDROM and floppy/DVDROM module connector in the flex bay
• Pathway for signals from the 100-pin floppy/FP/IDE connector to the front panel
connector
• Drive Activity LEDs
Notes:
The ATA HDDI board does NOT support hot-swapping hard drives. Doing so may cause data
loss.
ATA drives from both Western Digital* and Maxtor* have been found to have their interface
connectors placed in a location that is mechanically not compatible for use with the ATA
backplane of the server chassis SR1300.
7.1 ATA Backplane Layout
The ATA backplane resides in the drive bay of the server chassis SR1300. Drive bays 1 and 2
each have a cold-swappable ATA drive connector and a 4-pin power connector. The flex bay,
(the third peripheral bay on the right side on the front of the chassis) has a raised connector
providing support for an optional Floppy/CDROM or Floppy/DVDROM module. Additional
connectors include a 100-pin floppy/FP/IDE connector, which is cabled to the baseboard; two
40-pin ATA 100 connectors, which are cabled to the baseboard; a 34-pin connector, which is
cabled to the front panel; and a 6-pin power connector, which is connected to the power jumper
board.
The following diagram shows the board layout of the backplane.
