Figure 28. 50-Pin Connector To Slimline Optical Device; Table 39. J1L1 50-Pin Connector To Slimline Optical Device - Intel SR1500 - AXXMINIDIMM DDR-2 RAID Controller Cache Memory Manual

Intel® Server System SR2500AL
The IDE Optical drive assembly includes an interposer board which plugs into the back of the
optical drive. The interposer board is a card-edge type card that eliminates the need for cable
connections. As the drive assembly is inserted into the drive bay, the edge connector is blind
mated to a slot connector on the backplane.
The interposer board has two connectors. The first connector is the industry standard 50-pin
IDE interface used by all slim-line optical devices. The second connector is the card edge used
to connect directly to the hot-swap backplane board.
