CP3010-SA
Ethernet Interfaces
Gigabit Ethernet signals are available either on the front RJ-45 connector or on the rear I/O interface
due to the implemented switches on the CP3010-SA. Both Gigabit Ethernet channels are individually
switchable to front or rear I/O. Switching over from front to rear I/O or vice versa is effected using the
uEFI BIOS settings (default: front I/O).
Note:
The Ethernet magnetics must be placed on the rear I/O module. The Ethernet magnetics
center tap must be connected to the dedicated 1.9 V power supply provided by the CP3010-
SA (pin C12 on J2).
Note:
Pin C12 is a power supply
OUTPUT
. This pin
MUST NOT
be connected to any other power
source, either within the backplane itself or within a rear I/O module. Failure to comply
with the above will result in damage to your board.
