Description
In the Intel
®
Server System P4208CP4MHGC with the above mentioned Serial Numbers, the I
2
C cable is connected to
the connector labeled “I2C_OUT” on the backplane (Figure 1). However, to install a second backplane in the system,
the I
2
C cable needs to be connected to the connector labeled “I2C_IN” on the original installed backplane (Figure 2).
When installing a second backplane in the Intel
®
Server System P4208CP4MHGC, the two backplanes need to be
cascaded with two I
2
C cables. The first I
2
C cable should connect to the “I2C_IN” connector on the first backplane, and
the second I
2
C cable should connect from the “I2C_OUT” connector on the first backplane to the “I2C_IN” connector on
the second backplane (Figure 3).
