Rear IO Module
The Rear IO module CP-RIO3-923-8C provides additional GbE switch ports and out-of-band management access. With an
appropriate backplane, eight switch ports of the CP3923 that connect to the backplane can be accessed using the module.
For more information on the Rear IO module, see chapter 3.6

Technical Specification
1.3.1
Mechanics
Compliant to PICMG® 2.0 3U/8HP respective 12HP (Option 1d/2d/3d)(100.00 mm by 160 mm / height 40.64 mm typ.
respective 60.96 mm typ.)
The non-conduction-cooled versions use a one piece custom heat sink extending from the bottom to the top of the board
covering all major chips and ensuring stiffness of the complete PCB assembly. These boards have standard CompactPCI
front panels and handles.
The CP3923-RC cooling concept consists of a cooling frame with wedge locks which covers the complete top side of the PCB.
The RC version has no front panel.
1.3.2
CPCI Keying
The J1 backplane connector cavity does not contain any coding. The user or system integrator has to ensure that the back-
plane J2 pinning matches the one of the CP3923 (see chapter “J2 Connector” on page 33) to provide Ethernet connectivity
and avoid possible damage to the board or system.
1.3.3
Power
Supply voltages are:
• 5.0 Volt
• 3.3 Volt
• 5.0 Volt IPMB_PWR

WARNING
Only use a CPCI peripheral slot with 32Bit and rear IO support.
Operation in a 64-bit CompactPCI slot or in a system master slot causes
short circuit between 3.3V or 5V VIO supply rail and ground and can damage
the board.
