10/100Baset Port; Debug Port - Motorola MVME2400 Series Installation And Use Manual

10/100BaseT Port

The RJ-45 port on the front panel of the MVME240x labeled
supplies the Ethernet LAN 10BaseT/100Base TX interface, implemented
with a DEC 21140/21143 device.
Similarly, the Universe ASIC supplies an input signal and a control bit to
initiate a local reset operation. By setting a control bit, software can
maintain a board in a reset state, disabling a faulty board from participating
in normal system operation. The local reset driver is enabled even when
the Universe ASIC is not system controller. Local resets may be generated
by the
SYSRESET*, or a control bit in the MISC_CTL register.

DEBUG Port

The RJ-45 port labeled
supplies the MVME240x serial communications interface, implemented
via a UART PC16550 controller chip from National Semiconductor. It is
asynchronous only. This serial port is configured for EIA-232-D DTE, as
shown in
The

PPCBug. The port is configured as follows:
