Front/Rear Ethernet and Transition Module Options Header (J30)

A 40-pin planar header allows for selecting P2 options. Jumpers installed across Row A pins 3- 10 and Row B pins 3-10 enable front Ethernet access. Jumpers installed across Row B pins 3- 10 and Row C pins 3-10 enable P2 (rear) Gigabit Ethernet. Only when front Ethernet is enabled can the jumpers be installed across Row C and Row D on pins 1-10 to enable P2 (rear) PMC I/O. Note that all jumpers must be installed across the same two rows (all between Row A and Row B and/or Row C and Row D, or all between Row B and Row C).

The following illustration shows jumper setting options for J30. The factory default is shown where applicable:

SROM Configuration Switch (S3)

A part of the 8-position SMT switch, S3 enables/disables the MV64360 SROM initialization and all I2C EEPROM write protection.

The SROM Init switch is OFF to disable the MV64360 device initialization via the I2C SROM. The switch is ON to enable this sequence.

The SROM WP switch is OFF to enable write protection on all I2C. The switch is ON to disable the I2C EEPROM write protection.
